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 voices’ LFOs are in sync with each other. If you hold a chord and then play

new notes on top of the chord, all voices’ 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 won’t 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 voice’s LFO is independent. If you hold a chord, some voices’ 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 LFO’s 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.
