Modulation Destination Page 2

Select from the following modulation destinations. You can find out more about these parameters and how they affect the sound in their respective sections (for example: to learn how Pitch Envelope Attack affects the sound, see page 130 on Pitch Envelopes):

•	Pitch	•	Filter LFO Speed	•	Amp Envelope Delay
•	Filter Cutoff	•	Filter LFO Amp	•	Amp Envelope Attack
•	Amplitude	•	Filter LFO Delay	•	Amp Envelope Decay
•	Effect Send	•	Filter Envelope Delay	•	Amp Envelope Sus. Decay
•	Pitch LFO Speed	•	Filter Envelope Attack	•	Amp Envelope Release
•	Pitch LFO Amp	•	Filter Envelope Decay	•	Amp Envelope Amp
•	Pitch LFO Delay	•	Filter Envelope Sus. Decay	•	Portamento Rate
•	Pitch Envelope Delay	•	Filter Envelope Release
•	Pitch Envelope Attack	•	Filter Envelope Amp
•	Pitch Envelope Decay	•	Amp LFO Speed
•	Pitch Envelope Sus. Decay	•	Amp LFO Amp
•	Pitch Envelope Release	•	Amp LFO Delay
•	Pitch Envelope Amp

Note: "Amp Envelope Amp" is also known as Aenv Level (Amp Envelope function, page 10). For a discussion on using it as a destination, see the TIP on page 138.

Yet Another Note: When Portamento Rate is chosen as a destination, you will hear no change in that parameter unless it is at least set to 01 (Pitch function, page 9; or see page 121 in this chapter).

Modulation Level (-99 to +99) Page 3

At +00, the modulation source has no effect on the destination. Higher positive values increase the amount of modulation. Negative values also increase the amount of modulation, but with negative phase (i.e., if the modulation would normally be increasing with depth set to a positive number, the modulation would instead be decreasing at that same moment had the depth been set to a negative number).

In other words, if you choose Controller A as your source and Pitch as your destination, a value here of +99 will cause the pitch to rise as slider A moves up. A value of -99 will lower the pitch as slider A moves up.

TIP: When modulating Pitch, a Mod level of +72 or - 72 will give exactly one octave of modulation at maximum input.

Gate Mode (Off or On) Page 4

The Gate Mode function is available only on modulation routings 1 through 3. When Gate Mode is on, the Modulator will only be routed while notes are being played. In other words, you can gate the effect of the Modulator so that it stops when you are not playing any notes. This can be used on sounds with medium to long release times, where an interesting effect (like tremolo) is intended to be active while holding notes down, but deactivated as the sound is fading away after being released. Or if you're using the Sustain pedal, you can have vibrato present until the keys are released, but have the notes hang on until the pedal is released.
