13pin switching?

[XPM]

Hi
Does anyone have experience using a GS-20 with a Roland V-Bass and a GI-20? I cannot seem to figure out how to stop midi from being output of the GI-20 when the GS-20 is supposedly just selecting the V-Bass in A/B mode. The whole reason I got the thing was so that I could switch functionally between the V-Bass & GI-20 or use both simultaneous. What the heck good is it if when I A/B switch to just the V-Bass, the midi from the GI-20 continues to be sent to my sequencer??

Can someone help an old geezer to get unfrustrated? Surely this cannot be the way this thing is supposed to work. You would think that the A/B device merely eliminates output from either the A, or the B selection according to the switched position of the GS-20. Any ideas/thoughts?

Thanks,
Jeff

I think you mean US-20

Here is a Schematic

Yes, you are correct, my bad, it's the US-20. Apologies, now do you know the answer to an old cranks quandary?

Come on Guys/Gals, this is SUPPOSED to be the place where the technically brain dead like myself can come for relief, Whatz up!!!

I know this is not *that* lofty of a deal.

I mean, it the US-20 doesn't kill the midi coming from the GI-20 when it A/B switches to another device, what the heck good is the US-20?

Never mind, the issue is at an impasse. It seems that the good folks at Roland didn't design the US-20 to kill signal output (which is incredibly STUPID BTW) but rather to use the "midi volume" command to merely create the illusion of real switching. Lame as hell.

So anyone looking to use the glorious US-20 to switch between writing, and not writing midi notation, as a result of supposedly "switching" between two 13pin devices, forget about it, it won't work unless all you are REALLY looking to do is to turn the volume down on the hardware device that the the US-20 is "controlling" (not switching back and forth from, thank you brain children at Roland)

Time to call Axon.

I have noticed that on ocassion. I don't find it to be a deal breaker because I still needed something to drive 2 separate 13 pin input devices either simultaneously or alternately. I drive a VG99 and Axon MK II with it and it works excellently. For the money, I was unable to find a cheaper/better solution. I just use a volume pedal to control each unit and leave the US-20 on "Both" setting most of the time.

Hi MIDIme
Thanks for responding. The (whole) thing for me was an obvious need to actually switch between each unit or combine both. It would have been so simple for Roland to make that a reality. For the life of me I cannot understand how merely having to just turn the volume down would be an advantage to anyone.

I purchased an Axon USB 50 last night. I hope it's genuinely a better interface than the GS-20. They say it's supposed to be much faster and more so accurate with respect to notation minus so much of the unwanted transient bs. We will see. I like the fact that the Axon model is set up to be used with NI software. I really like NI and already use all their synths.
