It belongs with the audio designs in this gallery.
From the project
A central brain running on teensy or a lighter MCU to process any control signals (MIDI, CV, our own) into the same but adding logic, ADSRs, DCOs, CV matrices etc. to it
Praktisch: identiek aan musicbrain-matrix (zelfde schema, BOM en firmware-model), maar met de "gedistribueerd midden"-plaatsing: alle headers tussen de chips in plaats van aan de randen. Resultaat: 34% kortere audiobanen (gemiddeld 59 mm i.p.v. 90; langste net 154 mm i.p.v. 230) op een kleiner bord. Eén van de twee varianten bestellen.
Status: rev 0.3c — ERC 0, netlijst pad-voor-pad geverifieerd, DRC 0/0, 4-laags. Bord 154 × 133 mm.
