This is a very useful tool for quickly generating randomized midi sequences and arpeggios, but also as a midi note generator for when you have your hands full tweaking parameters on a vsti. Especially if you're working in a host that don't provide a qwerty note trigger function and you're on a laptop or don't have a midi keyboard, BallSequencer is invaluable!

The layout is clear and intuitive the little balls are bouncing around generating midi when hitting the walls, and all parameters are easily tweaked. The readme explains everything you need to know, and it never crashes.

Hard to give it anything but 1 on sound, as it generates midi only, and you really don't need presets, as it's super-easy to set up what you want it to do.

As for features, it could provide more balls or note slots, but it's just a matter of adding an extra copy to trigger more notes if you need it. It could be handy to have note lengths above 1000ms for long drones, but then the speed and room size would need values to match.

It might be a one-trick pony, but it's a lovely trick.. ;)
