The app is super simple, but that was the point, I wanted to create something that was beginner-friendly, and could allow anyone to create a fun pattern, without having any knowledge of music theory. The app also makes it possible to map physical knobs on an external MIDI controller to virtual knobs in the app, just by double-clicking on a virtual knob and then wiggling the knob you want to map on your device. Yes, there are already other browser-based music apps, but to my knowledge, at this time, no other browser-based music app offers this degree of flexibility and power.
