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
