Tempo Tremolo
Shape
+/-100. This adjusts the shape of the LFO waveform, from logarithmic to linear to
exponential. Positive values shape the waveform so that it spends more time in the
"up" part of the cycle, and negative values make it spend more time in the "down"
part of the cycle, as shown below.
LFO Shape
Smoothing
0-100. This allows you to filter the LFO waveform, so that it becomes more
rounded, less angular. With moderately high amounts of smoothing, the triangle
and square waveforms will start to approximate sine waves, and the discontinuous
peaks of the saw waveforms will become smooth transitions. With very high
amounts of smoothing, the waveform may loose much of its shape, and fall quite
short of its maximum and minimum values.
LFO Control
Frequency Knob, Manual Tempo, MIDI Tempo. The LFO speed can be controlled
either by the Frequency knob (including the mod source), the Manual Tempo knob,
or by MIDI Tempo (derived from MIDI clocks).
If this is set to Frequency Knob, then the LFO speed will be controlled by the
settings in the Frequency section, including the mod source and amount.
If this is set to Manual Tempo, then the Manual Tempo knob will set the basic
tempo, and the note value set in the Subdivisions menu will control the LFO speed.
If this is set to MIDI Tempo, then incoming MIDI Clocks will set the basic tempo,
and the note value set in the Subdivisions menu will control the LFO speed.
Phase
Initial Phase
This sets the point in the waveform at which the LFO starts. Whenever the Phase
Reset controller is received, the LFO will start from the Initial Phase point.
