122 is a simple beat generator I built as a little Unity 3D hands on project. It has two instruments with different patterns for each element. Each object represents one beat element and has four different patterns.
I was wondering if an primary graphical UI would work for an instrument. Playing 122 for the first time might take you a bit to figure out all the elements but in the end pretty much works like any other drum computer – ok, except the ready made patterns. You can download it for MacOS here.

Left click on any object = toggle on/ off

Right click on any object = change pattern
