4 track polyphonic CV and MIDI sequencer

Featuring extensive connectivity, the Tetrachords can act as a bridge between a modular system and the rest of a studio.

The unique, built-for-purpose interface turns a studio into a melodic and harmonic playground. Easily explore anything from unisons and simple melodies to dense note clusters, made-up scales and polytonal mayhem.

Inputs and Outputs:
- 4 Trigger/Gate inputs
- 4 V/oct CV Output
- 6 CV Mod inputs
- Midi In & out via 3.5mm jack (type A and B supported)
- Midi in & out via USB C
- i2c connectivity to other i2c modules eg, Disting ex and Just Friends

Main Features:
- 4 track polyphonic sequencer.
- Play with common scales or invent completely new ones using the Tetrachords scale concept
- Write harmonically rich compositions in real time and modulate them endleslly using the hands on interface or CV
- The 4 tracks can be harmonically linked or unlinked.
- The 4 tracks are triggered independantly by the 4 trigger/gate inputs or via midi in.
- The V/oct CV outputs can be freely assigned to any track allowing up to 4 voice polyphony on a single track. (more with i2c modules connected)
- Midi In & out can be freely assigned per track.
- The 6 Mod inputs can be assigned to modulate any parameter on the module via CV.
- Detailed CV modulation tuning allows precise parameter changes.
- Included SD card for saving and loading song data and user preferences.
- Save up to 8 songs. Each song containing 8 progressions. Each progression containing up to 8 patterns.
- Built in tuner, with the ability to save and recall custom calibrations that deal with specific oscillator drift.
