create the engines you wish existed

I made a sound platform packing 20 years of sound design experience, aiming to make a dynamic fun device that grows with players, learns taste and creates unique interactions thru games, sounds and generative art. Flash new engines, modules or entire device. CPU is your mana, spend it with bits.

every chip
you grew up with

Voice of a Commodore 64 SID. Crunchy Amiga Paula filters. A modern wavetable. Or code your own with agents using a native MCP server. 20+ engine modules ship with SIDKIT. SID leads, ESFM pads and drums, Mutable wavetables and voices, lofi samples, and FM feedback loops. Each audio slot takes one. Hot-swap mid-song.

slot architecture

4 audio · 1 seq · 1 game
any module · any slot

Six slots, each holds a module. Audio slots take engines — synths, samplers, FM, wavetable, your own. Sequencer slot drives them. Game slot triggers presets and patterns. Patches load instantly.

patterns,
probabilities, mod-locks

Pick the sequencer that fits the song. Step grid for tight beats with mod-locks (pitch · speed · mod · bit-rate per step). Markov chain when you want it to surprise you. Arpeggiator for fast ideas. Rain for cascades that never repeat.

games that
make sound

The game slot is a sequencer with sprites or generative visuals — mechanics you can edit in real time. Every collision, hit, and score triggers a preset. Chase happy accidents, fish for unusual sequences, or just play for fun.

everything

Six LFOs and six envelopes per audio slot. Forty-eight modulation sources running in parallel. A 32-slot mod matrix routes any source to any destination — across slots, across engines, across the whole device.

80 bits
to spend

Every engine costs bits. Every effect, every voice. The runtime reserves twenty for the system; eighty are yours. Stack a heavy ESFM and you'll feel it. Drop in a Paula and you've got room for two more. Bits are the budget. Spend them on what matters tonight.
