Boss GM-800 and GK-5

I'm pretty sure I've seen talk of GM-800 patches that can add voices depending on velocity — say a patch where it comes out as a sax when playing normally but adds in brass if you hit the strings harder.

How do you build a patch like that? I don't see an appropriate parameter.

II don't know exactly but it seems like an envelope follower that raised an input gain to the 'loud' voice so it only plays input levels that exceed the triggering level of the envelope? or a signal mixer that drops one level and raises the other relative to the envelope

Or to keep it simple, is there a way to turn parts on and off via MIDI?

Yes by the assign matrix, but you have to set it up for each preset. Hit menu, then control assign, then assign settings

In there you would use "tone sel part sw" for P1, P2, P3, P4. and on next page under source change it to midi cc# and use any midi cc number you wanna dedicate too it etc.. Make sure you save each preset after you're done setting it up.

Alternate route you can buy four boss fs-5u switches and 2 Y-cable things (forget the name right now) and go to control assign, then control function and set up ctl 3,4,5,6 in that matrix for "part on/off" etc.

I dug around in the editor trying to find a workaround (because Boss). I thought this would only select parts, not turn them on and off? Because Boss :oops:

That worked. Could even assign parts 3 and 4 to the same cc number.
 
This week, I'm starting to put together a deep tutorial video on using Zenology Pro to create your own new sounds for the GM-800. It'll include a full sound design how-to from the basic stuff to advanced synthesis techniques. If you've never programmed a synth in your life or you want some new tips, this video will be for you. I'm posting this info now to field any questions or topics you may want me to discuss. If so, let me know asap.
Cheers, TJ
