If a slot is empty, record instead of trigger. Both params for each slot and param for selected slot.
MCCY: ... or is it possible to Trigger select & record & play with only one button for each slot... Pressing first time button one would record slot 1 on predefined track. Next time pressing would stop recording and playback automatically recorded sounds, next time pressing would stop, next time start again etc. For new recording on same slot you'd need an extrabutton "empty selected slot"... So a quneo could simply handle 16slots or even up to 64 with corner control which I don't use because I play quneo with feed most of the time...
This is good for Launchpad-like controllers ... maybe it's even more important to implement this for normal MIDI control (with an option to disable that behavior).
re #108 Introduce record-if-slot-empty mode as local settings option
