To calibrate, set the SCALE switch to ±12 SEMI and RANGE to AUDIO, then trim the SCALE trimpot until the output is exactly 640 Hz at -2V input.
The module provides four main waveform outputs: sine, triangle, sawtooth, and square.
The audio range typically covers 1 Hz to 80 kHz, while the sub-audio range covers 0.01 Hz to 800 Hz.
