OPZ -> Modular

OP Z & Oplab:
→ midi output to Raspberry Pi (RealTime Linux)
3 channels for Drum triggers to Modular Kick, Snare, Hat
12 channels further triggers to Modular FX, Envelopes…
→ Oplab Channel 14 as a melodic sequence to Modular VCO
I tried to use I2C MCP4725 DAC in order to add at least two further melodic channel sequences but the voltage is not precise…
