80 & 90 SPEED
This parameter sets the LFOs' frequency or rate. VALUE range is
from O to +63 where O represents the LFOs' slowest speed and 63
the fastest.
LFO 1 : 81 SPEED MOD BY PRESSU RE
LFO 2: 91 SPEED MOD BY KEYBOARD
The initial speed of the LFOs can be increased or decreased by
another source of modulation. The speed of LF01 can be
modulated by Keyboard PRESSURE - pressing into the Master
controller's keys after the notes are played. LF02 can be modulated
by keyboard notes: playing high notes or low notes on the Master's
keyboard will speed up or slow down the LFO Speed.
LF01 PRESSURE
range is from -63 to +63. Using positive
VALUES increase the LFO speed when PRESSURE is added.
Negative VALUES decrease LFO speed when PRESSURE is
added. A O setting represents no effect by PRESSURE.
LF02 KEYBOARD
range is also -63 to +63. Using positive
VALUES causes the LFO to speed up as higher notes are played on
the Keyboard and slow down when low notes are played. Using
negative VALUES gives the opposite effect: high notes slow the
LFO and low notes speed it up.
82 & 92 WAVEFORM
This parameter allows you to select the waveform of the LFO that will
be used as the modulation source.
Periodic Waveforms
TRI
"Triang le" :
This is the most commonly used waveform which
can be described as a symmetrical wave with a regular up-down
shape. This waveform is primarily used for vibrato or tremolo effects.
UPSA W
"Up
or
Positive Sawtooth":
A variation of TRI where
the rising (positive) portion of the wave gradually reaches its peak
then drops off sharply.
DNSA W
"Down
or
Negative Sawtooth":
An inverted variation
of UPSAW where the wave starts at its peak and gradually decreases.
SQUAR
"Square Wave":
Another symmetrical waveshape where
the rising and falling portions are sharp transitions. The SQUARE
does not "peak" like the other waves but has equal high and low
"plateau" portions that give the wave symmetry. This waveform,
therefore, provides sharp high-low modulation.
Aperiodic Waveforms
RANDM
"Random Modulation":
This waveform outputs an
irregular modulation pattern used mostly for effects.
