The Korg MS-20 filter has so many clones that it's hard to count. So why make yet another one? Unless... It's not really a clone.

If you want to release an instrument to the market you might want to think beyond a basic synthesis building block. Sure, designing a filter circuit, an oscillator or a wave folder is a fun exercise. But, with so many basic modules out there, it's hard to stand out.

Steve's MS-22 from ThreeTom modular can serve as a good example here. Tom Verschooten from Threetom Modular took the MS-20 filter as a starting point and added a clever modulation matrix that makes it quite a unique filter that fits nicely under a 4HP panel. This is a good example of a worthy engineering and design challenge that pushes the modular space forward.

In this interview, Tom explains the various phases that lead to Steve's MS-22. He also touches on the importance of clear documentation, as well as the personal touch that can make a small manufacturer stand out.

Tom's process is quite unconventional (for instance, skipping the breadboard phase altogether). Listen in to learn more!
