Having fun with the demo performance setups so far.
One question - how can I set up midi commands to stop clips? (what right-clicking would do with the mouse).
I've tried using toggle buttons instead of simple push buttons, but no cigar... tried fiddling with adding button with no velocity playing the same note.
Oh.
Well, I had an idea before I finished writing this post and it worked, so I'll just post it if someone has the same puzzle (or a better idea

I added a button that plays a note on the same octave, but with no clip defined... so that stops the clip on that row no problem.
