The C-64 Synthesizer, in your browser
A Doctor Mix × Look Mum No Computer tribute, powered by Paul Slocum’s Cynthcart. Play the exact synth from the seven-year Commodore 64 build series — right here, no install.
Seven years of building. One click to play.
Between 2019 and 2026, Doctor Mix turned a Commodore 64 into a working synthesizer with a community of contributors. SIDMIX is the browser version of that finished instrument — the same Cynthcart ROM, the same emulated SID, the same MIDI CC messages Sam Battle’s panel sends.
