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: de analoge patchkast van de poly-synth. 8 IN-bussen × 16 OUT-bussen, elk 8 stemmen breed — een patch is een druk op de knop, opgeslagen en teruggeroepen door de Brain. Per stem schakelbaar: 8 stemmen zijn ook te splitsen in 2×4 met eigen routing. OUT-bus 16 is gereserveerd als meetbus naar de adc8, zodat de Brain niveaus en gains automatisch kan ijken.
