Chapter 7: Editing Effects
Mod
The Mod Function lets you control various effects parameters from the various controls
on your MIDI Controller (keyboard, after-touch, pitch-bender, etc.). This is extremely
useful when dynamic or real-time control is required in a live playing situation. It is
possible to control up to 2 parameters simultaneously. The Modulation assignments are
saved with the Effects Patch.
Don't confuse this Mod Function with the Mod Function used by the Programs; they
are independent destinations, though they can come from the same source.
Note: Modulating any effect parameter (with the exception of chorus speed) while
audio is passing through it can result in audio artifacts or noises due to discontinuities
in the modulation source.
Selecting the Modulator
The are two Modulators. You can select between these by using the PAGE [¨] and
[Æ] buttons. Page 1 displays the parameters of Modulator #1, while page 2 displays
the parameters for Modulator #2.
Mod Source
The Mod Source parameter selects the MIDI controller which will remotely cause a
change (modulate) in one or two of the parameters in the effects processor. Nearly
every MIDI controller can become a Mod Source (using controllers A-D, set in Global
mode, page 3), with the most common controllers appearing as a direct option in the
display. Quad Knob [1] selects the Mod Source. The options for the Mod Source are:
•
Aftertouch
•
Sustain Pedal
Mod Destination
The Mod Destination is the parameter that will be controlled by the selected Mod
Source. Quad Knob [2] selects the Mod Destination. The possible Destination
parameters are:
•
Pitch Speed
•
Pitch Balance
•
Delay Level
•
Reverb Decay
•
Reverb Diffusion
If the selected Configuration has a particular effect on more than one effect send (for
example, Config. #1 has a delay on each send), then some Mod Destination
parameters will be listed more than once. For example, the Delay Time parameter will
appear four times ("D1 Time," "D2 Time," "D3 Time," and "D4 Time"). In the case of
Pitch, where you can choose from various pitch effects, different parameters are
available depending on the effect chosen. However, the Mod Destinations retain their
names. Example: If the Resonator is the Pitch effect, the Pitch Speed Modulation
Destination controls the first parameter in the Resonator (Tuning).
Mod Level
The Mod level is the amount that the Destination parameter will be affected by the
Mod Source. Use Quad Knob [3] to affect the Destination parameter by a positive or
negative amount. Example: If the Reverb Decay was selected as the Destination with
