This build is easy but I expanded it a bit. First of all there is a simple version from ginkosynthesis and I found out the AE Modular version had a couple more ins and outs as well as a switch to use more formwares using the Mozzi Lib. The second part was to make it able to safely interact with modular signal levels. If the hagiwo modules learned me something then that.
