16x8 step sequencer
Breakout box allows for 4x multichannel/mult-CV use.
Up to 2 breakout boxes can be connected to generate up to 8 CVs and 8 gate outputs.
Per note/track pitch, velocity, and length, with 256 track memory locations.
CV IN – Control voltage input.
CLOCK IN – Clock source can be a square wave or gate signal (positive logic).
RESET IN – Positive voltage resets the Sequencer to the first step.
CLOCK (out) – Outputs a pulse per step. The default step setting is 1/16 (1/16th note). in note mode press SHIFT and PLAY together, and turn the encoder to divide the master tempo.
RESET (out) – Positive reset voltage output.
VEL (out) – Velocity (note/step level) output.
GATE (out) – 0/+5v trigger output.
CV (out) – Control Voltage output.
