While playing live and/or jamming, often you play a melody with one hand and tweak knobs with the other. this works great if youre modding knobs directly, but if you want to assign a modulation destination in the matrix, it's near impossible.
I propose two ways to do one handed mod destination assignment:
One could repurpose one of the buttons into functioning as an "Assign" button (e.g: press assign, press 1-8, touch knob to modulate).
Alternatively, one could reverse the current functionality of the 1-8 row; instead of holding down the 1-8 buttons to assign a modulation destination, you would only press them with a "waiting for destination" message box on the display until you choose a modulation source, with pressing it again to cancel assignment. and you would hold the 1-8 keys to switch modulation page.
This could be an option in the settings and would make jams and live playing much much easier!
