Korg Modwave 'Kaoss physics' - perfect for Drambo
Take a look at this: https://youtu.be/fHnkl6dSmgs?t=1800
Now imagine a bouncing ball going across an XY pad in Drambo, with various physics properties attached to both it and the 'walls' of the pad. The ball's X and Y positions would be assigned to synth parameters as per the current XY pad.
How about this for a new module, @giku ? :D
