@ustk forgive me, I'm not at my computer.
So I could do a button callback that is linked to a specific midi number? When this button is engaged, it would turn the audio on and disengaged turns the audio off.
This sounds like it could be just done in a sampler then? And I could just use the "combobox Preset window" to switch sample maps to change the sound.
I'll be back in the studio tonight to do some trial and error. I appreciate it!
