Delay (00 to 99) Page 3
This sets the amount of time it takes the LFO to fade in from no modulation to
maximum modulation. Sometimes, it is desirable to have modulation come in a
moment or two after a note has been played, rather than starting instantly. The
higher the value, the more slowly the LFO fades in.

Trigger (Mono, Poly, Key Mono, or Key Poly) Page 4
The Trigger parameter determines how the LFO should be triggered, or started.
There are four possible settings: Mono, Poly, Key Mono and Key Poly. When playing
multiple voices in a single Sound, each voice has its own LFO. However, the LFO
Trigger parameter determines whether or not they should be in sync, and whether or
not they can be retriggered independently from one another.
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.
Note: some modulation sources are by their very nature polyphonic, and can't be used
to modulate the LFO speed when that LFO's Trigger mode is set to MONO. (You will
be allowed to set up such Mod routings, but you wonÕt hear any modulation of the
LFO speed occur.) So if your LFO Trigger mode is set to MONO and you try to
modulate it using Note Number, Velocity, Release Velocity, Pitch/Filter/Amp LFO,
Pitch/Filter/Amp Envelope, Random, Trig Rate, Tracking Generator and/or
STEPTRAK, nothing will happen. However, modulation sources which normally
modulate an entire Sound at once will still have an effect while the LFO Trigger is set
to MONO. In other words, if you have LFO Trigger mode set to MONO and you
would like to be able to modulate the LFO's speed, use either Aftertouch, Mod Wheel,
Pitch Wheel, MIDI Volume, Sustain Pedal, Pedal 1, Pedal 2, or one of the A-D
Controllers as your source.
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.
