The LFO-01 is a low frequency oscillator which can be used as a control voltage source to modulate parameters on other modules.
The rate knob changes the frequency of the oscillator.
The wave button changes the waveform to triangle, square, or sawtooth.
Low frequency oscillator output.
Triangle, square, sawtooth
20hz to 2 seconds
+/- 1 volt (bipolar)
Low frequency oscillators are most commonly used to modulate oscillator or filter frequency, but can be used to control any parameter with a CV input.
