Toffoli and Margolis's CAM-6 cellular automata machine board for the IBM-PC was programmed in FORTH. I made a simulator, and this video shows some of the original FORTH code that I saved, as well as my own compatible FORTH CA rule computer that le me run the rules from the book, which produced lookup table for the hardware, which the simulator is compatible with. I've since rewritten it in JavaScript. It's not live coding, but it has a live performance user interface (quite weird and hard to figure out, especially if you haven't read the book, but I demonstrate it in the video).

Original FORTH code that drove the actual CAM-6 board:

My compatible CA compiler and glue to the simulator written in C:

An old version of the simulator written C, before I rewrote it in JavaScript:

This is a neat project and I don't think I'm aware of any sequencers that allow for arbitrary execution per-step (not that I am that deep into the space). The font choice for the website is really... interesting. I don't think I can recall ever feeling this dyslexic trying to read the copy here.

Cool, and I love the retro font. I had a Vic-20 (early 80s) and Commodore PET 2001 (1977) I am learning Odin, and I was going to try creating live coding environment with scripting in Forth and with the gui and rest in Odin, but for audio and graphics. I was inspired long ago by Paul Batchelor's Sporth and Tidal (now tidal cycles?). Forth is a great language. You can make an compiler/interpreter in a few days. John Earnest's ok.js is also cool. I like stack and array languages, so when I am not playing in J, I use Uiua. Uiua has the capability to do audio and graphics/animations and scratches my array/stack itch.

for FORTH like synthesis environment you will want to check out SAPF! (by James McCartney author of SuperCollider) https://github.com/lfnoise/sapf

Wow, I never saw this! I like APL/J/Uiua, so this is perfect. Uiua is both stack and array based. Thanks!
