Inputs (2)
CV-1 Inputcv-5V to 10VChannel 1 CV input that records external voltages (e.g. LFOs). When a cable is patched, the knob acts as an offset; the module switches between knob and CV input based on which is being changed.1045
Reset Inputtrigger0V to 10VA high pulse resets all active tracks and restarts them according to the last playback mode setting (one-shot or loop). Has no effect during RECORD or STOP mode.1045

PLAY ButtonbuttonShort press (less than 0.5 s) triggers one-shot playback; long press (more than 0.5 s) starts loop playback. Also used in combination with STOP button to toggle between Speed and Offset functions.1045
Polarity SwitchswitchSlide switch on the module PCB that selects between unipolar (0 to +10 V) and bipolar (±5 V) output voltage range for all channels.1045
RECORD ButtonbuttonStarts a recording session (LED blinks). Press again or wait until maximum record time to stop recording; playback loop then begins automatically. Can be pressed from Stop or Play mode.1045
Speed/Offset FunctionbuttonToggles the knob function between Speed (adjusts playback rate) and Offset (shifts CV output up or down by up to ±5 V). Default after power-on is Speed. Knob center position is the original record speed for Speed, and zero offset for Offset.1045
STOP ButtonbuttonActivates Stop/manual mode. Holding STOP and pressing PLAY toggles the knob between Speed and Offset functions in Play mode.1045
