I find myself hoping for a way to preview sounds in the headphones before having them on the master (or individual) outputs.
Immagine you are jamming with friends and you want to program a sound and write a sequence without this sound going to the master/individual out: a button combination that would route ONLY this particular sound on the headphones out so you can work on it while the rest is playing, and when you are done you can re-route it to the main/individual outs
wouldn’t be it a killer feature for live playing/jamming?
