Mudras

Mudras is a eurorack sequencer that reads the distance of your hand and turns it into pitch. It records what it plays, and plays it back.

How it works

• An external trigger on D5 advances the sequencer.
• The interrupt service routine only sets a flag. Step advance, record, and playback logic run in the main loop.
• Hold the D4 button to record. Release it to play back the stored sequence. Entering record mode from playback resets recording to step 0.
• The distance sensor is read continuously. In scale modes, hand distance maps to a note index. In linear mode, it maps directly across the full 12-bit DAC range.
