Disting Mk4 Algorithms Cheat Sheet (DRAFT) by

A guide to Expert Sleepers' Disting Mk4 and the various algorithms it provides

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Welcome & Conven­tions

Welcome! This cheat sheet describes the algorithms available in Expert Sleepers' Disting Mk4 Eurorack module. There are so many great features crammed in to this tiny thing that I felt a compact algorithm guide would be helpful to master using it. I hope you find this guide to be useful. Please refer to the excellent manual for other functions and detailed algorithm info.
Choosing an algorithm: press S to enter menu, S again to select Algorithm, rotate S to choose an algorithm, then press S to switch to that algorithm. Click click twist click.
