Procrastinator
A delay whose chains feed each other.
Like many delay pedals in parallel, where any one of them can feed back into any other. A CLAP and VST3 plugin for Linux and Apple silicon Macs, and an Audio Unit on the Mac.
-
Tymbal
A synthesizer system, under construction.
Many synthesis engines in one patch, thirty-two channels, a mixer and a sequencer, written in fixed point so it can run on an FPGA. Not finished, and no release yet.

mini-800
Synthesizers for the Raspberry Pi.
Thirty-eight software synthesizers, each modeled on a hardware instrument from before about 2000. They run on a Raspberry Pi, on Linux and on a Mac, or as plugins, and they're meant to be played live.

Stagewheel
A tonewheel organ in an FPGA.
An open-source stage keyboard with a rotary speaker, computed sample by sample in the fabric of a Terasic DE10-Nano and built to be played live.
Ben Cox’s Projects
Things I make for making music: a delay effect, two families of synthesizers and a tonewheel organ. Most of it runs as software on a computer or a Raspberry Pi; Stagewheel and Tymbal go further, into the logic of an FPGA. Each project's own code is dedicated to the public domain.
