The Radical Chip is a collection of digital noise algorithms by Dirty Electronics and Max Wainwright. Originally made as an expansion chip the Mute Synth 4.0, it has taken on a life of its own with the PCBSNR and DIY SNR versions, Radical Nails ,.
The sounds range from gritty digital sounds and extreme noise to pure tones and silence. The sounds may also be thought of as programs that have complex behaviours that can be interacted with through the Mute Synth 4.0’s controls, knobs, audio or control voltages.
Go to the shop to buy one, or check our dealers.
• 64 algorithms
• Random program select
• Two voltage inputs for sound or CV
• 8-bit PWM digital output, easy to filter with passive low pass filter
• Incredible source of modulation for e.g. FM.
• Comes with pre-bent legs for easy install
• FUN

Putting in the Radical Chip (in a Mute Synth 4.0)
~~mp3 files coming~~
In July 2023, the Radical Chip code was updated to contain 64 programs, just as in the new Radical22. Due to the number of devices, I can’t offer a chip replacement service. But you can always get a new chip and give the old one to a DIY-ing friend. You can upload the code of course, but unless you already have a PIC programmer I wouldn’t recommend it.
The Radical Chip came with a limited edition A2 risograph printed poster/booklet on Microcomputer Music: a music made from mini microprocessors and raw electronics that is always in-flux, noisy and may be overwritten.
The poster has since sold out at noise.technology, but is still available from Dirty Electronics.
