3. Press the PAGE UP button again, and the display shows:
Of course, your actual screen may show a different target parameter.
4. Choose the first target parameter with the VALUE buttons. Different
configurations offer different target parameters for modulation; see
the list at the end of this section.
5. Press the PAGE UP button again, and the display shows:
6. Use the VALUE buttons to select the desired amplitude (scaling) and
direction (positive or negative).
7. Repeat steps 1 through 6 for as many mod source/target combinations
you want to program (up to eight total).
Since a continuous controller will modulate a target parameter across a
range of possible values, the idea here is to set the Mod Target
parameter's value equal to the controller's zero value. Then, set the Mod
Amplitude's value equal to the maximum amount of modulation that
you want the controller to generate.
Before you panic, let's explain this more fully with an example. Let's say
that you wanted to modulate your Reverb Decay with a continuous
controller foot pedal.
First, set the Mod Source to the pedal's MIDI controller number. Then
set the Mod Target to Reverb Decay.
Now, with the pedal set to its heel position (all the way back), set the
Reverb Decay parameter (in the Mix section) to its "default" levelÐfor the
sake of this example, let's say 50. This represents the amount of reverb
that you will hear when the controller is all the way back in the heel
position (if you want to keep the Reverb Decay completely off until you
step on the foot pedal, set this value to 00).
