The LFO module generates modulation voltages mostly below the audio range; this module offers
- PWM modulation for the Pulse out
- RATE knob for controlling the frequency
- SLOW / FAST switch for two frequency ranges; with FAST the rate can go into the lower audio range
- Triangle / Sawtooth switch; changes the waveform of the output
- PULSEWIDTH knob, this sets the pulsewidth of the according output
- control LED for sawtooth/triangle and for pulse
- Three separate output signals: Square (even duty cycle), TRIANGLE/Sawtooth, Pulse
