I realize quantize may be turned off for the keyboad input, but i feel it would be great for triggering cells on the surface as well.
I see a huge opportunity for creating wonk beats, or broken beats; without any major changes. I notice that the cells also respond well with swipe gestures for triggering. The fact that you already can place the cells anywhere or at any distance from each other on the surface is ideal. Especially that one can set a cell interaction to hold! Combine the hold with "turn off on exit" and it's on for making loose and wonky beats. If one could also adjust the size of the cell, that combined with allready being able to place the cells wherever you want on the surface would make this style of playing more fluid.
Imagine clusters of very short sequences and or samples. To give you an idea of the possibilities, this great but no longer supported Beatsurfing app is where i draw the idea from. If you can eventually also allow for customization of the cell size, that would be a plus! I realize this is a competely different app cause it's only a midi controller, but if you just watch i think you can see the potential is already in your design for something else amazng to already add to the awesomeness of this app.
