LFO's
The Low Frequency Oscillator (LFO) can be used as modulation sources of all voltage controlled
parameters, such as; oscillators frequency, pulse width, and cutoff frequency. LFO's has a wide rate range of
60 seconds (0.01 Hz) to 16 milliseconds (60 Hz). The waveforms shapes can be modified by applying voltage
control for rate speed and output level. LFO can be gated by MIDI GATE's.
LFO's offer seven waveforms:
*
Sample & Hold with 2 additional
slewed shapes
*
Triangle
*
Saw tooth
*
Ramp /inverted sawtooth)
*
Square
