Voltage Controlled LFO
The EMW VC LFO is a low frequency oscillator module with 4 waveforms: SINE, TRIANGLE, SAWTOOTH, and SQUARE (with pulse width control). You can use it to alter the frequency or the pulse width of a VCO, change the VCA amplitude to produce vibrato effects or in any other modules modulation input to alter its behavior over time. This is a very useful module and a great tool in a modular setup.
