The visualiser shows perfectly even touch response but when I set up a bunch of control areas as MIDI notes I get random velocity excursions where a softly touched note triggers a much higher velocity than it ought to. It’s hard to reproduce but definitely occurs, even with sensitivity downgraded (I’ve gone from 0 to 3 which at that point gives a fairly natural touch response for piano). But there’s definitely a bug here. It will happen every 30 seconds or so if you play a reasonable number of notes. Suddenly one note will be played at a much higher velocity even though you didn’t strike the surface any harder.
