Patch a cable from your computer's or phone's headphone output into MODEL. FREQUENCY at noon.
Power the module on holding the left button.
Notifications off (any other sound spoils it), then play the WAV. The level meter rises from the 4th LED: set FREQUENCY for 2 or 3 lit. The bottom LEDs circle as it loads. All red: press left, play louder.
Switch to duo mode
Both buttons: duo mode. Again: the original firmware.
Left: stereo models (yellow). Right: split (red).
Calibrate Do this once
In duo mode, hold both buttons for 2 s: the bottom LED pulses green, and OUT buzzes (turn your mixer down).
Patch OUT into V/OCT. When the LED flashes green, press left: it pulses yellow.
Move the cable to LEVEL. When it flashes green, press left: the model's LED is back. Done and saved.
All red: pressed too early, or wrong jack. Press a button and retry. Uncalibrated, voice 2 can be 25 cents per octave off.
Usage
V/OCT and LEVEL: the pitches of voice 1 and voice 2 (LEVEL stops at about −0.7V). Empty LEVEL: one voice. TRIGGER pings both.
Stereo: OUT left, AUX right. Split: voice 1 on OUT, voice 2 on AUX.
