— capabilities
Every sync protocol,
one module.
MIDI Synchronization
Receive and transmit MIDI clock signals with sub-millisecond jitter. Sync your Eurorack rig to any DAW, hardware sequencer, or drum machine over standard 5-pin DIN.
DIN SYNC 24
Using a DIN Sync TRS Adaptor Cable you can both send and receive DIN sync signals to synchronize with legacy gear.
Ableton Link
An onboard WIFI module allows wireless sync over your studio network. Join a Link session and every connected device — hardware or software — locks to the same tempo and phase.
USB Connection
USB-C port for firmware updates and MIDI host functionality. Connect directly to a computer to synchronize using MIDI-over-USB.
Pulse Sync
Synchronize to an external pulse or square-wave. Set the incoming pulse rate — 1/4, 1/8, 1/16, to tell System Clock how many pulses represent each musical beat.
3x CV outputs
Three independent clock outputs with configurable divisions, phase, and amplitude.
