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: acht gate/trigger-ingangen. Leest externe klokken, triggers en voetschakelaars de software in, met ingangsbeveiliging en een gedefinieerd rustniveau per kanaal. Combineer met een jack8.

Status: rev 2.0 — ERC 0, netlijst pad-voor-pad geverifieerd, DRC 0/0. Spec: doc/spi-bus-spec.md v2.0. Bord 50 × 45 mm, 2 lagen.

- Slot 2×12 via bus.j1map; H 80 → 45; kanaalkolommen recht onder de J2-pinnen. DOF_IN-mapping (firmware-contract) ongewijzigd. - Koper via freerouting; GND via de vlakken + hechtvia's.
