Mono . All voicesÕ LFOs are in sync with each other. If you hold a chord and then
play new notes on top of the chord, all voicesÕ LFOs will be moving in the same
direction and at the same speed. Because of this, modulating the LFO Speed using a
voice-specific source (such as velocity or one of the envelopes, for example) will have
no effect (you will be allowed to do this, but you wonÕt hear any difference). This is
because these modulation sources are meant for polyphonic purposes. These include:
Note Number, Velocity, Release Velocity, PLFO, FLFO, ALFO, PENV, FENV, AENV,
Random, Trig Rate and Tracking Generator. However, modulation sources which are
not voice-specific will still have an effect while the LFO Trigger is set to MONO.
These include: Aftertouch, Mod Wheel, Pitch Wheel, MIDI Volume, Sustain Pedal,
Pedal 1, Pedal 2, and Controllers AÑD.
Poly. Each voiceÕs LFO is independent. If you hold a chord, some voicesÕ LFOs will
be moving in one direction while others move in the other direction. If the LFO
Speed is being modulated (by one of the envelopes, for example), the LFOÕs of each
voice may be running at different speeds.
Key Mono. This is identical to MONO, but whenever a new note is played, the LFO
is retriggered, instead of continuing from wherever it may be in its cycle.
Key Poly. This is almost identical to POLY, but whenever a new note is played, the
LFO is retriggered, instead of continuing from wherever it may be in its cycle.
Pitch LFO (Page 2)
Level (00 to 99)
This is the base output level of the Pitch LFO. If you want to have a constant value of
vibrato, even without using the Mod Wheel or Aftertouch, set LEVEL above 00. The
Mod Wheel and Aftertouch will add or subtract from this base level.
Example: If
Level is set to 10 and the Mod Wheel parameter is set to 10, there will always be
some vibrato, and raising the Mod Wheel will add more vibrato. On the other hand,
if the Mod Wheel parameter is set to -10, raising the Mod Wheel to the top will cancel
out all vibrato.
Mod Wheel (-99 to 99)
This is the modulation amount of the Mod Wheel over the Pitch LFOÕs Level. A
positive value raises the level when the Mod Wheel is moved up, and lowers the
level when moved down. Negative settings of this parameter will
decrease the
output level of the PLFO as the Mod Wheel is raised. Since the output level of the
PLFO cannot be less than zero, a negative setting of the Mod Wheel parameter will
have no effect unless either the Aftertouch or the Level is set to raise the PLFO
output. If both the Level and Aftertouch are set to 00, and the Mod Wheel parameter
is set to -99, the Mod Wheel will have no effect on the vibrato from the PLFO.
Aftertouch (-99 to 99)
This is the modulation amount of Aftertouch over the Pitch LFOÕs Level. A positive
value raises the level as more Aftertouch is applied. A negative value will lower the
amount of PLFO level as more Aftertouch is applied.
