What’s new in the DIY world of Music Thing’s Workshop System

It’s a Very Workshop System Jamuary. Music Thing’s patchable music lab-in-a-lunchbox has proved that small-batch personal hardware can attract a select, dedicated community sharing great stuff with one another. Let’s catch up with what’s been happening in that magical village of synth wonder in the past year. Don’t forget, the ideas and code here are all open — meaning this could inspire more.

Over 20 years ago(!), Tom Whitwell’s Music Thing (the blog) was an inspiration and rival to this site. Now, Music Thing Modular carries on that name — now a platform for everyone’s imagination in hardware rather than on the screen. I got to catch up with Tom on what’s happened in 2025, to give you a snapshot of The State of Workshop System as we start the new year.

Quick refresher: the Music Thing Modular Workshop System is a complete modular system inside a hard case, sold as a kit or pre-assembled via resellers. It’s analog, but its centerpiece is the Computer module, a tiny brain that’s totally hackable with program cards — and that openness is what makes this round-up so interesting. Those innards run on the RasPi’s RP2040 32-bit 133mhz dual core microprocessor and 264K memory — way beyond the first computer I used as a kid. And anything that runs on that CPU works — Arduino, C++, and Circuit Python, for instance.

For more, you can read my original write-up on the Workshop System.

Patch Notes by Vincent Maurer clearly started as just a way to store patches as you would in a notebook, but grew. It’s a fully patchable simulation with audio, MIDI keyboard input, and external audio input — at least an approximation. You can save your patches locally as JSON, PNG, and PDF, and load JSON and PNG files locally or via sharing link. I’m convinced this sort of thing (plus text) is the future of documentation.

Dune Desormeaux’s amazing blockbuster program cards

Not everybody that picks up a Workshop System is going to create their own program cards. But the handful of folks who have are doing mind-melting stuff. Dune Desormeaux has been especially prolific.

Goldfish is a lo-fi delay/looper effect with modulation — short memory, ya know, like a goldfish.

BYO Benjolin augments the modules already in the Workshop System with everything you need to do something “rungler-y,” inspired by the legendary Benjolin designed by Rob Hordijk. (Some history)

Sheep is a granular effect with pitch shifting and time stretching that uniquely comes in both lo-fi and hi-fi versions. It’s Clouds-esque, yes, but it’s its own animal. And that animal is the sheep. (We’re one big happy granular family here; somehow, there are always little tweaks and twists, especially as details like buffer size, window, and various quality decisions have an enormous interconnected impact.)

Blackbird is the one actual port/remix — it’s monome crow compatibility (an open 2hp module with Lua processing and I/O), running on Workshop System, plus some extras beyond crow.

What does that mean? (Crows, sheep, what’s happening?) It gives you a few superpowers:

Here’s the original crow hardware:

Write and upload your own (simple) program cards in the Lua (5.4.8) language. Upload to the WS computer via the “u” command in druid (on a non-WS computer). Uploaded scripts are saved to flash on the physical card itself– So you can write many different blackbird cards and hot-swap! If you want the name of your patch saved to flash for future reference (printed to host at startup) make the first line of your script start with three hypens ---.
