Just bought an Old School from Nova Musik (arrives on Tuesday…) but had a question about the VX-351. Does it function 100% as it would on a Voyager with the exception of the “Touch” section (A,X,Y,Gate). Are these ports just dead or mapped to something else?
Thanks
They do nothing.
Well, they’ll set the modulation amount for any parameter you connect to zero, and you’ll have no way to trigger / control that parameter. So if you were to connect “Touch X” to the “Vol” input, you’d have one quiet Voyager with no way to get it to make a sound.
That actually manages to be LESS than “nothing.” 
The 351 is still pretty cool though. I just got one a few days ago. Haven’t really spent too much time with it, but it’s easily worth it just for the extended control it gives you over certain things like LFO speed and Pitch. You can get the LFO down to like one cycle per minute; without the 351 the lowest is approx. one cycle every 5 seconds. Also works the other way around; MUCH faster LFO rate than without the 351.
Pitch is the same way; at the lowest settings you’ll just hear an occasional knocking sound because the oscillators are just barely vibrating. I’m assuming this is accompanied by the lowest earthquake rumble known to man, but I haven’t had the chance to run it through big enough speakers. 
This is why Im thinking that they need to make a touchpad controller and a little piggyback board for the OS users to get that extra modulation out of it…but of corse if they did that the touchpad woudl probably just have its own outs anyway, eliminating the need for the incorporation with the Vx351.
Better yet, just make something that would go in between the cable either at the Voyager’s end or on the Vx351’s end that would send the messages that you need to complete the picture there.

I suppose that without all of the mapping functions that a Voyager has in the firmware, and not having a CPU controlled way to affect the amount of touch surface umm… touched, you are really just talking about a 2 dimensional touchpad that acts like the ribbon controllers that I’ve seen.
I’ve seen some wild things done with the Voyager’s touch surface but it seems very foreign to me.
Thanks for the replies.
