This looks and plays great! GUI is really awesome, clean and simple but at the same time powerful.
Thanks man!!!
The only thing I miss
(and maybe it`s there but I can`t find it) is HOLD option. If you plan to add it could have two modes:
#1 When you press any new midi note it removes everything and uses just those new notes
#2 When you press any new midi note it just adds it to a sequence. If you press midi note that`s already in the sequence it removes it.
