2.5 LFO (Low Frequency Oscillator)
The LFO modulates the cutoff frequency. It has the parameters LFO Rate, LFO Depth,
LFO Wave and LFO Reset which can be adjusted using the appropriate controls under
Modulation 1.

LFO Rate
Speed of the LFO with an adjustable frequency from 0.01 Hz to 10 Hz
LFO Depth
Intensity with which the LFO modulates the cutoff frequency (0 to maximum)
LFO Wave
Selection of possible waveforms. In addition to "traditional" waveforms such as square
wave, triangle, sawtooth, inverted sawtooth and random, waveforms are also available
that can be manipulated by incoming trigger signals. These can be used to achieve
rhythmic modulations.
LFO Reset
One strength of the LFO is its reset options. In this case this means restarting the
LFO, starting at the lowest value. Resets can be triggered via the MIDI clock, Note On
messages or Control Change messages.
The following is a detailed description of the LFO Wave and LFO Reset parameters.
2.5.1 LFO Wave
This section covers the various waveforms of the LFO. The following explanations apply
in the event that the LFO is not reset (LFO Reset control in Norm position). The triggered
waveforms process the trigger signals selected with Trigger Source.
The waveforms correspond to the illustrations below. S/H is a waveform in which the
LFO generates random values.
