Modulon
A Eurorack module that converts MIDI 2.0 UMP messages from USB into analog control voltage and gate signals. It bridges modern DAWs and MIDI 2.0 hardware directly to the modular world — with 16-bit CV resolution that far exceeds what MIDI 1.0 could express.

Why MIDI 2.0
MIDI 1.0 note velocity is 7-bit — 128 steps. MIDI 2.0 UMP expands this to 16-bit per parameter, which maps cleanly onto the DAC's 16-bit CV range and gives you 65,536 steps of voltage resolution per output. Per-note pitch bend, per-note controllers, and high-resolution CC are all handled natively.
// CV assignment example (firmware config) ch 1 note → CV 1 (1V/oct pitch) ch 1 vel → CV 2 (velocity, 0–10V, 16-bit) ch 1 cc1 → CV 3 (mod wheel → filter cutoff) ch 1 gate → GATE 1
