A pocket-sized modular synthesizer built around a Raspberry Pi Pico (RP2040), with all patching done on a 12×12 grid instead of physical cables.<\/p>\n\n\n\n

Oscillators, filters, envelopes, and a handful of other modules get placed onto the grid and wired together however you like, so the same box can become a DX7-style FM patch one moment and a slow, drifting drone the next. Audio streams out over I2S, with the synthesis math running in fixed-point to keep the Pico’s core from choking under a full patch. A rotary encoder, a volume potentiometer, and a 128×64 OLED handle all the interaction, and a 3.5mm TRS-A MIDI input lets it take notes from an external keyboard or sequencer. It runs off a LiPo cell and a booster board, small and portable enough to carry around.<\/p>\n\n\n\n

A desktop simulator ships alongside the hardware, letting patches be designed and auditioned before ever touching the device, with patches transferable both ways. It comes with eight demo patches plus a few built-in presets that mimic the DX7, and saves patches to EEPROM so nothing is lost when it’s powered off.<\/p>\n\n\n\n

Status: Finished.<\/p>\n\n\n\n
