TASCAM DP-004 POCKETSTUDIO: Portable 4-Track Recorder ($199 street)

[Jon Chappell]

There are lots of miniature recorders to choose from these days, with the most recent surge being in the two-track market, and Tascam has more than one worthy dog in that fight (see the DR-1, DR-2, and the new DR-07). But Tascam is still one of the major portable multitrack innovators (they started the whole industry with their PortaStudio, which is a household word amongst recordists) and their new DP-004 reminds us once again of why they are still leaders in that arena, too.

The DP-004 four-track recorder is slightly smaller than a drugstore paperback book, and strikes the perfect balance between dedicated front-panel control (it doesn’t bury too many functions into menus) and miniaturization. In other words, it’s large enough to read and operate comfortably, with plenty of tactile controls, but small enough to hold in one hand or fit into a jacket pocket. It operates on four AA batteries as well as AC power, so you don’t have to worry about charging a proprietary battery, as you must do on some two-track recorders. It saves CD-quality audio data to SD cards, and interfaces with a computer seamlessly via USB.

If you’re a first-time buyer of a small recorder and like the idea of portable quality recording—but are haunted by whether two tracks just might not be enough for all situations—the DP-004 may just be the unit for you.
If you’re already a portable two-track owner, the DP-004 is probably only slightly larger than your current unit, and is a good choice for any situation that requires or may require more than two tracks.

The DP-004 is a four-track recorder that allows you to record two tracks simultaneously and up to four tracks total, via overdubbing. Of course, you can monitor all previously recorded tracks and, as with any hardware-based recorder, there's zero latency and no “direct monitoring” considerations involved (that's for you computer types). You can use the 1/4" inputs or the built-in stereo microphones to record, and the mics have three sensitivity settings, in addition to a trim control and a master level control. The mics are not phantom powered and each is hardwired to its corresponding input (meaning the left mic is permanently assigned to Input A, the right mic to Input B), as are the corresponding A and B 1/4" jacks. Of course, any input can feed any track, and the DP-002 has a “Monox2” mode, where both Inputs A and B are output as a combined mono signal from both the left and right channels. That solves the issue of "hearing out of one ear" when recording a mono source. Neat.

The front panel tells a lot about the architecture of the DP-004. You have a mixer setup on the lower left of the unit with four pan and level knobs, which control the playback of the four tracks. Above those are the input settings—separate trims for the two inputs (Inputs A and B) and a Master input level control. At the bottom of the unit are the track-arm switches for recording. Even though the lower half of the unit is playback oriented, I like having the track-arm switches on the outside edge of the front panel as it makes them easy to jab when I’m recording. (And they intuitively correspond to the tracks they’ll be recording and playing back on.)

Over on the right side, also along the bottom edge for easy finger-jabbing, are the transport controls. There’s Stop/Pause, Play, and Record. Directly above Stop/Pause are two buttons for rewind and fast forward if playback is active, or, if playback is stopped, RTZ (return to zero) and LRP (last recording position, which is very handy for recording a passage again—or again and again).

A large data wheel lets you change parameters that appear in the display, and four function buttons along the bottom of the display also help you page and scroll through the various menus. It’s appropriate that these are placed right next to the display, as the readout is small and not illuminated. Though it’s well laid out, it is difficult to read in any position except straight on. I often put my stapler behind the DP-004 to prop up the unit and lean the display toward me. (There is a 10-step contrast control to help optimize different viewing angles.)

Additional switches on the DP-004 invoke various modes, and all are well-labeled and intuitive. If you have any experience with any kind of mixer, live or recording, you will never need to crack the manual. Even when it wasn’t obvious from the front panel how to do something—like create or load a new song or perform other disk-management duties—it was actually quicker and easier to hit the Menu button and scroll around than it was to consult the manual. And for a four-track recorder this deep, that’s saying something about the interface and workflow design.

This is not to say the manual is not good. In fact, it's excellent, which is no surprise, as Tascam has always had great manuals. Not unrelatedly, Tascam offers the manual in pdf form. I encourage anyone interested in any unit with an available pdf manual to download it and explore the features themselves. You can download the 7 MB file here (http://tascam.com/products/dp-004;9,16,3707,19.html).

The mic diaphragms are countersunk into the front panel such that the grilles are flush with the surface. This may not look as visually impressive as the external capsule configurations you see on many two-track units, but the mics are of decent quality, at least for the onboard variety. Here’s a photo of how the mics appear on the front panel.

While we’re looking at the unit, here’s a shot of the back, where you can see the 1/4" inputs.

http://jonchappell.com/HC/TascamDP004/DP-004_Back.jpg

The 1/4" jacks are spaced far enough apart that if you’re using bulky XLR-to-1/4" adapters for your mic cables, you’ll be able to fit both in fine.

Below are two shots of the side views. The mini headphone jack doubles as a line out, and the input switch optimizes the gain for a guitar or line-in source. Note that the USB connection, while not the standard square connection, is a common one found in many USB devices, such as cameras. So it shouldn't be too hard to replace should the included one become lost or damaged.

http://jonchappell.com/HC/TascamDP004/DP-004_Sides.jpg

Before we get into the specifics of the operation and editing, my overall impression is that the DP-004 succeeds on many levels, but the one of the most noteworthy of those is how easy it is to use. Rather than making you page through menus and offering a bewildering choice of cursor options, the DP-004 puts most of what you need to capture audio right on the front panel in the form of knobs and switches, the way nature intended.

I never expected to get very far with this unit without cracking the manual—which is not a knock; in fact, it’s typical for a multi-featured unit in a small format that you go to the manual often. That’s the trade-off you make. But I was surprised to see that just by touching literally two buttons (three, if you count the power-on switch), I was recording my first track and watching my levels in two places (the overload indicator on the input LED and in the LCD track display’s meter). Okay, I thought, how about overdubbing? I hit Stop, RTZ (return to zero), the REC track-arm button on Track 2 and the Record button on the transport and there was my original track playing back in my headphones. I could also hear myself live, indicating I was recording on track 2 (and watching my live level in the display).

Mind you, all of this is occurring within about 15 seconds of getting the unit out of the box. No kidding.

So right away, before I’ve even considered the sound quality, the editing capabilities, and some of the other in-depth features (like setting the auto-punch points, which I’ll get into), I’m thinking that this is as easy to use as my digital two-track. And it’s got everything that does—onboard stereo microphones (albeit non-phantom-powered), SD card storage, 16-bit/44.1 kHz format, battery power, USB off-loading of files, etc. So the question becomes, can I use a 4-track that’s this portable and convenient for situations I’d normally reach for my two-track? Granted, it doesn’t fit into a shirt pocket, but it does fit into a jacket pocket.

[Jon Chappell]

Of course, a four-track has an additional advantage over a two-track besides the addition of two tracks: Track bouncing.

This is a cool feature that allows you to bounce up to four tracks down to any other number of tracks, including one. The reason you bounce in the first place is to combine two (or more) tracks to one (or two, if you need stereo) in order to free up an additional track to record on. So you might bounce, say, three tracks to two (which yields you two available tracks to record on), or you might bounce three to one, leaving you three potentially open tracks.

Any scenario you can think of is easily and intuitively rendered on the DP-004, including bouncing all four tracks to one. Now, those of you old enough to remember the bad old days of analog four-track recording will recognize the significance of this, because you know that you usually have to leave one track open to bounce your remaining three tracks to. It doesn’t have to be blank, but you’ll lose whatever material you have on that destination track while capturing the other three. And even then, it’s a bounce-to-mono operation. Very limiting.

But with the DP-004, you can fill up all four tracks and then bounce them to any single track, or to track pairs 1-2 or 3-4. In this way the unit becomes almost like a virtual 6-track during track-bounce mode (four tracks bouncing to two). And of course, unlike analog, you don’t pick up any additional signal noise, as it’s a digital bounce. This is quite an improvement over the analog way.

Here’s how the manual (p. 69) states it:
Use this unit’s bounce function to mix already recorded tracks (1 – 4) down to one or two tracks. Multitrack tape recorders can only bounce to an open track (in other words, they cannot record to a track that is also a source of the mix). For example, tracks 1 – 3 could be bounced to track 4, but tracks 1 – 4 could not be bounced to track 1. This unit, however, does not have this limitation. You can bounce tracks 1 – 4 as a stereo mix to tracks 1 and 2 (stereo bounce), or bounce tracks 1 – 4 as a mono mix to track 1 (mono bounce).

And here's the flow chart of how you can actually bounce all four recorded tracks down to two (a stereo part) and have two available tracks to record additional instruments on:

http://jonchappell.com/HC/TascamDP004/DP-004_Bounce.jpg

_

Note that the bounce operation occurs in real time. You hear the tracks playing and you can make level and pan adjustments while the playback tracks are recording onto their new destination tracks. So this isn't similar to a "disk-based operation," like song copying, for example. You're still in control of the mixdown (at least with respect to level and pan parameters, anyway).

The best thing is, if upon playback you don't like the mixdown, you can hit Undo and go back and try again. You haven't overwritten tracks 1 and 2. Try that on a PortaStudio! ;)

Keep in mind that even after a successful bounce--a keeper--you can bounce again (and again) if you need to.

Oh, and one more thing: Because you're bouncing in real time, you can record a new part through the input. Just the thing for that 12-string double. And again, there's no great risk on this "live while bouncing" approach, because if you screw up your live take, you can hit Undo and start again.

[Jon Chappell]

It should be pointed out (and in fact the manual does this) that a good way to bounce is to first copy your song in its last saved state (just before you bounce) to another location on the SD card. That way, you'll always have the original tracks, even after several rounds of bouncing. So the routine would be that any time you decide to perform a bounce, you simply copy the song in its current state to another card location. (You can copy multiple songs using this operation, as the interface uses checkboxes to select from all available saved songs; see the graphic below.)

The above operation might seem like a candidate for the "duh" category, but realize that this is impossible on an analog machine, or at least highly impractical. But if your idea is to take a 4-track into "the field," you can have it both ways: capturing audio on its own track to preserve it in pristine form and mixing down multiple tracks with impunity. Because the DP-004 makes it so easy to copy a "song" (really just your "last saved state" before bouncing), you'll always have the original tracks to do some serious multitrack work once you get back to your desktop-based DAW.

Alternatively, you can use the Undo and Undo History (it's just like Photoshop; you can go backwards in time with multiple undo's) to correct momentary mistakes and to back out of a series of bad decisions, but of course, you don't have to. You can leave your mistakes intact, go to the original, saved file, copy it, and simply try again, saving to another location. The only caveat with this approach is the bookkeeping might get a little confusing, unless you write down what you're doing.

[Jon Chappell]

Having the ability to record four tracks is great, but it’s a little bit unfinished if you can’t lock in a mixdown. In the old days, you’d have two machines: a multitrack and a master deck (PortaStudio/two-track cassette, ADAT/DAT, etc.). Then when computer DAWs came along, you could bounce to a stereo wave file (or to two tracks right within the multitrack project, as a good house-keeping move). But with a digital 4-track, we’re kind of back to square one as far as the master issue. If you have four great tracks and you want to generate a stereo file, it requires you mix on the fly every time you want a copy. And the mixes won’t be identical if you have to perform any fader or pan movement while the song plays. Plus, you have to do it real time.

“Problem Solved!” says the DP-004, with its Master Mode. This is a feature of the unit that allows you to save a master mixdown as part of the song file on the card (a very DAW-like solution, say the folks like me who mix to two open tracks of the multitrack project).

This solves the real-time mixdown issue, it allows you to either play or upload the stereo mix at will, and it does one more thing: allows you to record an additional overdub while mastering. Yes, the DP-004’s inputs are still active when bouncing down four tracks to a master via the master mode. So if you have all your tracks finalized, and you can perform whatever fader and pan moves (if any) easily during the mixdown mode while recording another source, you have this added flexibility. If you screw up the live input, simply start over. You can't micro-edit bad spots during this pass the way you can in multitrack mode (you would have to start over if you made a mistake), but it’s still an unexpected and welcome feature.

_
Additionally, once you have recorded a master, you can import it back into any track pair (e.g., 1-2, 3-4) in the multi-track project by using the edit function called “Clone Track” (a track-duplication function). Again, very DAW-like and cool!

When you have completed the recording of your master, you can have it recorded by an external recorder in the audio domain (via the headphone/line out jack) or convert it to a stereo wave file that can be exported (via USB) to a computer for further conversion (say, to mp3) or importation into a DAW or two-track editor (Peak, WaveLab, etc.).

Structurally, a “Song” in DP-004 parlance means the four tracks of audio, plus an available master mixdown. (You need to be aware of this when using the unit, as the data is stored in two different places.) The best way to use the master mode in the field is to record as many tracks, overdubs, bounces, etc., as you need to in multitrack mode (i.e., when tracking), and then--as quickly as you can get to it--do a mixdown to master mode. You can always do another, better mix when you have more time, or fly the unmixed tracks into a computer. But getting a two-track song as part of the recording process is a priority—even if it’s only two tracks with no fader or pan manipulation. That’s what makes the DP-008 behave like—and compete with—a two-track.

HOWEVER, it should be emphasized that you don’t have to master anything if you just want to export (via audio or data) a track or tracks. For example, if you’re recording a lecture or interview (and you don’t care about the level or pan, and there’s no mixing involved), you just want to be able to offload that track (or tracks) as fast as possible. And you can do this, too. See the screenshot below, which shows the export function. Again, the use of checkboxes here reveals how versatile this is. (Note that I caught a mistake in the manual, too, with my red insertion of the word "not." If you recorded a lecture in mono, and don’t have audio on tracks 2, 3, and 4, they won’t show up--a handy bit of feedback.)

[It's Only Bass!]

Hi Jon,
Thanks so much for the in-depth review! I’ve been with Teac and Tascam since the days of the 2340. Right now I’m using a DP-01FX.

I would buy a DP-004 this minute if it would do one thing: Export a file as an mp3. I’m a songwriter, and I have spent so much time and money trying to get around this issue.

If Tascam wants a device that will catch fire like the Flip video camera has, all they need to do is insert some firmware that will allow songwriters and artists to create a song and upload it directly to their MySpace (or whatever other) page. Right now, I have to record something on my DP-01, master it to an Alesis Masterlink, burn it to a CD, take the CD to work (because I have Windows Vista on my home machine), rip the CD to RealPlayer, then – THEN – I finally have an mp3 I can email.

I love everything about the DP-004 EXCEPT the fact that I would STILL have to do all those steps to get an mp3.

Consider this: With my Flip camera, I can record myself playing a song, plug it into the USB port, and upload it to YouTube 30 seconds later. Whoever is first to market with a multitracker that does this is going to MOP UP.

I’m hoping you or someone can suggest this to Tascam. Someone is going to do it. It should be Tascam – they’re the leaders.

Thanks for your time, and thanks again for your great review.

[Jon Chappell]

It's hard to argue with that logic, "It's Only Bass!" :thu:

Tascam, are you listening? :)

[Will Chen]

A buddy of mine just picked one of these up and the sounds he's getting using the built in mics is simply great. We plan on using it to run sound for some video at this year's Dallas Guitar Show in April so we'll really be putting it to the test in a variety of situations and db levels.

[PetersReviews]

Thanks for the review! I was looking for an easy to use digital recorder to recommend to my students and this might be the one.

Yes, the mics are quite good. I think all those "memo recorders" from RadioShack (micro-cassette as well as digital) did portable recorders a disservice by putting in cruddy onboard condensers. You really can get a good sound with onboard mics if you do it correctly, and you don't need to invest in expenisve capsule design, either. The DP-004 is a good example of creating really good mics that are, how shall I say, unprepossessing in their appearance (that is, countersunk into the panel). (The Line 6 BackTrack + Mic is another example of good mic technology, BTW.)

[Jon Chappell]

Thanks for the review! I was looking for an easy to use digital recorder to recommend to my students and this might be the one.

This would be a good unit for students because it's so simple to operate, yet it follows the standard mixer paradigm (so any knowledge gained here will be transferrable to other, standard systems).

I haven't gotten a chance to get into some of the more sophisticated editing features yet (like track clone, clear, silence, cut, insert, etc.), but you don't have to use these features if you're just using the unit to capture multitrack audio.

[writerjohn]

I purchased a DP-004 just before Xmas. Jon's review is excellent both in its depth and organization of info on the features and functions of the unit. Being a technical writer by profession, I also appreciate his use of graphics and photos to support his review text. Great job Jon!!!

Thanks for the kind words, John. Nice to hear from a fellow colleague. As a technical guy, I'm sure you're appreciating the simplicity and power of the DP-004, too. :)

I would buy a DP-004 this minute if it would do one thing: Export a file as an mp3. I’m a songwriter, and I have spent so much time and money trying to get around this issue.

Another workaround is to transfer your mix as a WAV file (which it already does), then convert it to MP3 using some software. iTunes will do this for you, it's free and lets you fill in your contact info, album name, etc. Then you get to keep the full-resolution mix on your computer for CD burning as well as an MP3 for uploading.

Well put. Although it would be a convenience to have the choice of .wav and .mp3 right in the same unit, it's easy enough to do using almost any audio editor these days (and very simple using the free iTunes, which is both Mac and PC, as you point out).

(The poster that synthetic is responding to mentions that he has a Vista machine at home, so he's already set up for easy .mp3 creation.)

If you can have only one, it's better to record in .wav and have to convert to .mp3 rather than vice versa (as you can't "get back" the lost quality by recording to .mp3 initially, even if you convert to .wav for burning to CD). To me, not having onboard .mp3 conversion isn't a deal-killer, but I understand both sides of the argument.

Hi,

I read your review of the Tascam and was so impressed that I went to the store to look at it. I tried it and the Boss Micro BR. The Boss seemed cheap and gimmicky in comparison.

I ended up purchasing the Tascam and have been happy with it so far.

Cheers,

Boytbpc

[auramac]

This sounds great- how would it compare to the Boss 600 (which, of course, is twice as expensive, but 8 tracks with effects)?

[boytbpc]

Maybe because this is my first recording unit of any kind, I'm having one small difficulty. If I have a section of a track I want to replace, how do I do it? I know how to set my "In" and "Out", now how do I get the unit to only record over that section?

Cheers,

Boytbpc

[Muddslide]

Jon--I think we all owe you a debt of gratitude for that very in-depth, excellent review.

I am very intrigued by this machine. I guess I'm a bit of a luddite...I just stopped using an old cassette Tascam 4-track not long ago, though I have experimented with digital recorders and computer recording for several years.

I had been planning to undertake some new home recording projects using a TonePort GX USB interface and some multitracking software (and still plan to) but having something this portable is also very appealing.

That said, It's Only Bass! is 100% correct about outputting as mp3s. The company that tackles that little issue will make a mint off it.

[writerjohn]

Jon is correct in his post that the wave file is what you want as the source, as the MP3 has data removed. Yes, it would be nice to output as MP3, but then the device would have to be more $$$ to include the coversion program, menu updates, etc.

Since most computers have a WAV to MP3 convertor built into their Windows Media program, it is not really an issue. It might be a different situation if the DP-004 had a built in CD burner. I suppose it might be nice to download to a handheld MP3 player, but most of those convert WAV to MP3 also, don't they?

The key features of the DP-004 that surprised me (good) is the quality of the internal stereo microphone and the warm, non-digital sounding recording quality. I just picked up a TASCAM DP-02 to used in my home studio but have not recorded with it yet.

[Bag302]

Can I use this as a USB mic on my laptop to create video clips with quality audio?

I want to record make video clips of my kid and I jamming (he plays electric drums). I would like to use my web cam for video and get the audio using the line in directly from his drum kit and I would mic my cab using the internal mic of the DP004. Is this feasible? or is there a better way?

[Gomer Pyle]

I want one that will record 4 tracks at the same time and have 4 outputs so I can do the mixing in my studio. I am using the DR-1 now to record my band rehearsals. I take mon 1 out of the board and mix all the vocs into the left track and use mon 2 and mix the guitar, bass and drums to the right track. It would be nice to be able to mix the instruments in my studio the next day, Paul.

[burningsg]

Jon, could you clarify something concerning Master Mode ? If one mixes down all four tracks in Master Mode, thus freeing up tracks 1-4 can they then rerecord to tracks 1-4 again while monitoring the previously mixed down 'master tracks' ?

A sort of six track... Four tracks plus the two (monitoring only) 'master tracks' ???

Thanks for the great review... I've been looking for a comprehensive review on this unit, It sounds like a winner !

Well, I picked one of these up and think it's a keeper. It does what it's intended very well. The internal stereo mics sound fantastic. I was able to get great sounds micing my valve jr., going stereo direct from my Vetta line outs and capturing an open air recording of my kid & I jamming. I am extremely pleased with the sound quality so far. In fact, I haven't recorded anything that sounded bad. Stereo imaging is excellent - almost sounding doubletracked as you adjust the pan.

To answer my question above: you cannot use the unit as a USB mic (p. 45 of the manual).

[Jon Chappell]

If one mixes down all four tracks in Master Mode, thus freeing up tracks 1-4 can they then rerecord to tracks 1-4 again while monitoring the previously mixed down 'master tracks'?

No, the closest you can get is to record an input signal while bouncing four tracks. The master tracks are a separate sound file that you access in a different mode.

[burningsg]

It should be pointed out (and in fact the manual does this) that a good way to bounce is to first copy your song in its last saved state (just before you bounce) to another location on the SD card. That way, you'll always have the original tracks, even after several rounds of bouncing.

One last question Jon, if you don't mind...

Is it then possible to record to three tracks, save that song and now with two copies of the same song (song 1 and song 2) keep song 1 and bounce-to-mono the three tracks on song 2 to track 4 to use as a guide and then re-record tracks 1-3. Then... save song 2 to say, song 3.
By doing this over and over and copying each song you will end up with multiple un-bounced tracks to then move over to your daw....

Is this possible ???


I'm coming from 'tape' so this is all new to me... yet amazing.

I can tell you're coming "from tape," because you're so dang clever. People who come from tape (and analog synths, for that matter) are just so industrious when it comes to this kind of thing. Mostly, it's because we (I come from tape too) had to be.

Unfortunately, the short answer to your question is no, because saving to song mode is a one-way street. You can't use the files from song mode as a source to feed the recording tracks in multi-track record mode. The tracks don't allow for "file importation" from within the machine itself.

But you could export the songs you create to a computer and import them back into the tracks, using the method you outline above. Importing an external file from a computer (which could be one you've just offloaded from the DP-004) into a track is explained on pages 97-98 in the manual. This brings up the question, though, that if you're going to use a computer for this "import work-around," why not just open up a DAW in your computer and do it there?

The thing to remember is that the different modes don't talk to each other. So all bouncing operations have to be done in recording mode, on the track (as opposed to the track + song) level.

But I still think the ability to fill up all four tracks and be able to bounce those -- plus an input source (if you like) -- to any combination of tracks is amazing. Especially if you "come from tape" like we do. :)

Jon, I had to laugh when I read your comments on 'coming from tape'... thinking of all the hoops we had to jump thru just to get simple things done.


Now... not to belabor the point but I have to say I didn't understand why you felt this wouldn't work. I'll say that I probably just didn't explain it correctly. However I did re-read the manual (PDF) and can't find a reason why it shouldn't. So if you don't mind I'll try again...

We record to tracks 1-3 leaving 4 open. we now save this as song 1. The docs say these tracks can be exported as wavs to a pc. Which we'll do later.

We now save song 1 as song 2. And put song 1 aside. In song 2 we bounce tracks 1-3 to track 4 as a time keeper and now have 3 tracks open. We record to tracks 1-2 leaving 3 open. Song 2 now has 2 tracks plus an open track and the bounced 'time keeper' track .

We now copy song 2 as song 3. Song 2 is put aside and again as the manual states we can export tracks (1-2) from song 2 to a pc... but later.

Move on to song 3, bounce tracks 1-2 plus the time keeper track (4) to the open track 3. We now have 3 open tracks plus the timekeeper track(3). We now record to 2 of the 3 open tracks always leaving a track open to bounce to, to keep it all in sync.

Now... we can go on as long as we have room. However, as the manual states all the tracks we've saved along the way. The tracks in songs 1 to wherever we end can now be exported to a pc, song by song, (or track by track). Except the time keeper or bounced tracks which we don't need anymore.

In this example we should have 8 mono non-bounced tracks (in 3 songs) that can be - according to the manual on p.99 - exported to our daw. All in sync with each other And all done only in multitrack mode.

I hope I explained it correctly this time ... what are your thoughts ?

Thanks again, SG




HOWEVER, it should be emphasized that you don’t have to master anything if you just want to export (via audio or data) a track or tracks. For example, if you’re recording a lecture or interview (and you don’t care about the level or pan, and there’s no mixing involved), you just want to be able to offload that track (or tracks) as fast as possible. And you can do this, too. See the screenshot below, which shows the export function. Again, the use of checkboxes here reveals how versatile this is. (Note that I caught a mistake in the manual, too, with my red insertion of the word "not." If you recorded a lecture in mono, and don’t have audio on tracks 2, 3, and 4, they won’t show up--a handy bit of feedback.)

I sketched out your routine in a schematic, and it all works as you say, and you understand the value of saving copies of songs to preserve the original tracks while working on copies.

But what you describe is also true for a conventional four-track tape machine. It doesn't capitalize on the improved features offered by the DP-004. So although your routine is correct, the true advantage would be realized if you outlined a process that could only be done on the DP-004 and was impossible on a conventional (i.e., tape) platform. [edit]

For example, in step 1, you say record on track 1-3, leaving 4 open (which you bounce to in song 2). Well, you could record all four tracks in song 1 and bounce to track 4 in track 2. Can't do that with tape, but possible on the DP-004. You'd gain an additional mono track this way, in your master copy.

Going on, in song 2 you record new tracks 1 and 2, leaving 3 alone (the original from song 1) and bouncing 1, 2, and 4 to track 3 (for song 3). But you could record three new tracks (1, 2, 3), because you don't need to leave 3 open, and you have your time keeper (4) which will make it to the next generation. Again, you gain a master mono track this way, which you'll use later on your computer.

As I say, your method works, but the DP-004 way, you can get more mono tracks with each pass (and still have your time keeper advance to the next generation).

Try your "bouncing roadmap" again, but record all four mono tracks in song 1 and bounce to one as a time keeper. In subsequent versions, record three tracks (and over the track you're currently leaving open, as you don't need to do that here, as you would with tape).

BTW, in post #11, I allude to the DP-004's ability to save "states" of the song, in order to keep the master, unbounced tracks along the way, which is exactly the feature you're using to do your bounce routine above:

From Post #11. Jon Chappell wrote: It should be pointed out (and in fact the manual does this) that a good way to bounce is to first copy your song in its last saved state (just before you bounce) to another location on the SD card. That way, you'll always have the original tracks, even after several rounds of bouncing. So the routine would be that any time you decide to perform a bounce, you simply copy the song in its current state to another card location. (You can copy multiple songs using this operation, as the interface uses checkboxes to select from all available saved songs; see the graphic below.)

The above operation might seem like a candidate for the "duh" category, but realize that this is impossible on an analog machine, or at least highly impractical. But if your idea is to take a 4-track into "the field," you can have it both ways: capturing audio on its own track to preserve it in pristine form and mixing down multiple tracks with impunity. Because the DP-004 makes it so easy to copy a "song" (really just your "last saved state" before bouncing), you'll always have the original tracks to do some serious multitrack work once you get back to your desktop-based DAW.

Yes, I see your point... I thought that might be the case from what you had alluded to in your post #11. Though I wasn't sure since I don't actually own the unit yet.
With a little stretch it's essentially a 64 track portable digital recorder that you could take on the road with you for $175.00... not bad !!!
They've come a long way from my Tascam reel to reel and Portastudio 144/244.


A buddy of mine just picked one of these up and the sounds he's getting using the built in mics is simply great. We plan on using it to run sound for some video at this year's Dallas Guitar Show in April


Have you had a chance to work further with the internal mics ? Are they that impressive (for the price) ?
And also, what is the reality on running this unit on a good set of rechargeables such as the Sanyo Eneloops, or other high capacity rechargeables used in today's digital cameras ?


Thanks again Jon....

SG


BTW.... if anyone is interested Tascam is offering a $25 rebate this month.

[ferrdoggsmd]

Thanks for the review, I have been eyeing this for a while, I think you just sold me on it.

Sorry, meant to say "only be done on a DP-004 and not on a conventional (i.e., tape) platform. (Fixed via edit above.)

[Bag302]

Jon, or anyone else, I am having trouble updating the firmware. I am getting an error code: "ERROR product" when I try to perform the update after the files are transferred from my PC to the dp004.

I've tried 2 different PC's and 2 different SD cards. I tried both leaving the .zip file zipped and unpacked. Same results.

I'm going to contact Tascam support tonite, but was hoping someone else encountered and resolved this problem.

Thanks!

[Fuzzwah]

The file you are looking for is a single file named "dp004-43.102". If you copied over the folder(s) that were unzipped, that would have gotten you that error (that's what I did to get that error anyway :) )

Just make sure your UTILITY folder has only the "dp004-43.102" file in it, and it should work. If it doesn't, definitely contact Tascam.

[Bag302]

Thank you Fuzzwah! I'll give it a shot when i get home.

On another note, I see that Tascam sells a tutorial DVD for $40. Seems kinda high. Is anyone familiar with it?

[Bag302]

Got it!! Thanks again

[thelorddread]

There are lots of miniature recorders to choose from these days, with the most recent surge being in the two-track market, and Tascam has more than one worthy dog in that fight (see the DR-1, DR-2, and the new DR-07). But Tascam is still one of the major portable multitrack innovators (they started the whole industry with their PortaStudio, which is a household word amongst recordists) and their new DP-004 reminds us once again of why they are still leaders in that arena, too.

The DP-004 four-track recorder is slightly smaller than a drugstore paperback book, and strikes the perfect balance between dedicated front-panel control (it doesn’t bury too many functions into menus) and miniaturization. In other words, it’s large enough to read and operate comfortably, with plenty of tactile controls, but small enough to hold in one hand or fit into a jacket pocket. It operates on four AA batteries as well as AC power, so you don’t have to worry about charging a proprietary battery, as you must do on some two-track recorders. It saves CD-quality audio data to SD cards, and interfaces with a computer seamlessly via USB.

If you’re a first-time buyer of a small recorder and like the idea of portable quality recording—but are haunted by whether two tracks just might not be enough for all situations—the DP-004 may just be the unit for you.
If you’re already a portable two-track owner, the DP-004 is probably only slightly larger than your current unit, and is a good choice for any situation that requires or may require more than two tracks.

You can check out the specs here (http://pro-audio.musiciansfriend.com/product/Tascam-DP004-Portable-4track-Digital-Multitrack-Recorder?sku=250011&src=3TP9CH1&ZYXSEM=0&Prime=).

that really is a great book.
one of my faves.

Just tried recording on mine for the first time. I'm happy with the audio quality of the built-in mics.

Not so happy about the metronome. I'm struggling to get it at the right volume, in relation to audio playback when I'm overdubbing new audio. It's either too loud or too soft. And it's sounds like a scratch instead of the usual "tick" of a metronome.

[Fuzzwah]

Have you tried different headphones?

I was using earbuds to track with (Koss "The Plug") and I was having the same problem. It was a chirping sound I could barely hear, and when I cranked the metronome I could almost feel what's left of my hearing getting "chirped" away!

I tried out an old set of Pioneer cans I got in the mid-eighties and the metronome sounds fine. Maybe it has something to do with how far the drivers are from your eardrums?:confused:

Would it be possible to upload an audio clip of the metronome ?
Possibly along with your audio tracks... for perspective.

SG

[girevik]

Turns out my metronome sound level problem was caused by not plugging the headphones all the way in. I have to give the plug a good shove to click it all the way into the headphone jack.

More questions:

Is there a way to export a track directly into my computer via USB?

When I connect the USB cable between DP-004 and Macbook Pro, the DP-004 becomes unresponsive - it won't let me to anything until I eject the DP-004's drive icon from the Macbook Pro desktop.

Has any fellow DP-004 user/owner had to play with the SD card partition sizes?

I was silly enough to not get a larger SD card before going to a cello festival - the DP-004 complained about memory being full about 40 min. into a 1.5 hour class that I tried to record. Because the DP-004 uses a dual partition system (MTR partition for recording/playback, FAT partition for backup), I learned the hard way I don't actually have anywhere close to a full gig of memory - the actual memory is more like 450 MB because that's apparently the default size of the MTR partition. It looks like the other half of the card goes to the FAT partition.

I now have a problem in which I cannot export a track (almost 300 MB in size) because I get a Disk Full Error type message. I'm hoping I can get around this by doing a Song Backup, then Restore from the Backup to a larger SD card.

[girevik]

I figured out how to convert my large-size DP-004 recordings into .wav files. While I was unable to finish the process while I was at the festival, I did copy all the files that I had in the BACKUP folder.

1. Make sure FAT partition is empty. This can only be done from the computer.

2. Copy song backup file from computer to the BACKUP folder on the DP-004 FAT partition.

3. Eject DP-004 from the computer and unplug USB cable

4. On DP-004, follow instructions to do "Song Restore".

5. Reconnect DP-004 to computer to reactivate USB connection. Delete file from BACKUP folder on DP-004. You may have to do "Empty Trash" if you're on Mac OS or "Empty Recycle Bin" if you're on Windows.

6. Eject DP-004 and disconnect again

7. Now do a WAVE->Export Track. This creates a .wav file in the WAVE folder. If you skipped Step 5. above you will get a "Disk Full" type error. If so, cry/swear/whatever and go back to Step 5.

8. Reconnect DP-004 to computer.

9. Copy your shiny new .wav file from the WAVE folder.

10. Delete the file in the WAVE folder on the DP-004.

11. Copy next backup file to the DP-004 BACKUP folder. If you get a "disk full" type error, do the "empty <OS-specific can>" thing. Then repeat all above.

I just got a 4GB SD card. Hopefully I can skip some of the extra copy/delete steps above to make this whole process less tedious. It's a shame the DP-004 doesn't just record to .wav straightaway but instead forces the user to go through this somewhat convoluted process.

[Ubertakter]

I know this might sound callous, girevik, and I really don't mean it that way but you should read the manual. The manual talks about the dual partition thing (I don't really like it either) and that you have to "mix down" tracks to get a wave file. Also, you can directly manage all songs on the DP-004. There is a demo song that comes on the 004 as well. Maybe it was taking up a little extra space.

If the manual doesn't make any sense to you, I would be happy to try to help you with any other problems.

I'll try that next time. I believe you are talking about Export Master instead of Export Track, which was what I was doing. I suspect though I will still get a "Disk Full" error if I attempt an Export Master if there is a 250MB file in the Backup folder (FAT partition).

It's possible that I missed something in the manual. Allow me to post a simpler list of steps below for recording two 30 min. music classes (1 hour is too much for a 1GB card). Any specific suggestions you have to make this list shorter would certainly be welcome.

1. Record (1GB card is full or nearly full at around 35 min. mark)
2. Export Track or Export Master to export recording to WAV file
3. Connect laptop to DP-004 and wait for USB sign to appear
4. Copy WAV file to laptop
5. Disconnect USB with usual procedures
6. On DP-004, do a Song->Erase on the "song" just recorded, to make room for next class
7. Repeat above for next class.

[Ubertakter]

Ah, I see. Yeah, it appears that the WAV file size is the same as the recording size on the MTR partition (or close enough not to make a difference), so if you tried to export it to the FAT partition when the partition isn't empty, well... there's not enough space.

How did the your recording turn out (what you did get down anyway)? I just recorded some of my family recording music and it turned out pretty well considering the environment (noisy room, DP-004 sitting on a chair in front three or four people singing with guitars) and that I had the mic gain set too high so there was some clipping.

[burningsg]

Ubertakter and girevik, can you guys comment on the quality of the built in mics ?
I'm interested in how well they sound...

How have you used them, and what did you think of the results ?

SG

[Ubertakter]

I've only used the 004 here and there, but it sounds good, especially considering what it is. You wouldn't think a couple of condenser mics in a little box would sound that good. I don't have any good samples handy, but I found a couple that I think are representative of how it sounds.

On this site just search for DP-004. There are five recordings that mention the DP-004 specifically, although I suspect he used it for all his recordings.

It was tricky tweaking the input level to avoid clipping yet try to capture the class while participating in the class too. For at least one recording, the instructor's voice is quite soft compared to the cellos in the room, so that kind of hurts from the perspective of re-listening to the recording to refresh one's mind with information. Still, I was glad to be able to have recordings from 4 different classes.

[Mirando]

Back to John, if input A switches between line/mic (presumably preamped mic signal then?) and guitar, which level is input 2 set on - there's no switch.

As in using it for 32 or 64 track DAW the short point is you can export 3 tracks in one go keeping them as individual mono tracks, and keeping a time track for subsequent passes(recordings). Right?

I'm gonna get one anyway.
Brilliant report!

[World Downfall]

Is it possible to plug an external mixer into the DP-004? It's a shame it does not have any kind of line in. Has anyone tried plugging an external mixer into the 1/4 jacks for some type of EQ and recording more then two instruments at once with decent success? Thanks.

Yes, I do this all the time.

You can set the inputs to "Line In".

I wonder, is there a possibility to rename tracks? (not songs)
I was able to export only four tracks (track1, track2, track3, track4) to wavs,
but no more ('duplicate name' message appears)

If not - maybe they will include this option in future firmwares?
