Modulation Wheel
The modulation wheel is the most common controller, and can be found on
nearly every MIDI keyboard. It is usually used to produce LFO effects (regular
wavering of the sound, like vibrato and tremolo). Since it is so common, the
MU128 features various parameters that are reserved strictly for modulation
wheel control.
In the Multi mode, the modulation wheel can control Pitch LFO. The Per-
formance mode features both Pitch LFO and Filter LFO. For more information
on these parameters, see pages 124 and 139.

Some Applications
Changing the Brightness on a Piano Voice
Though you can use the Equalizer (page 116) to adjust the brightness of a
Part’s Voice, you may find it convenient to be able to change the character of
the sound “on the fly,” as you play. This uses the AC1 Filter Control param-
eter. Try this with the Grand Piano Voice (001:GrandP #).
Operation
1 Call up the Edit menu.
From the Multi Play mode, press the [EDIT] button.
2 Select and call up “OTHERS.”
Use the [SELECT </>] buttons, then press [ENTER].
3 Select “AC1FilCtrl” and set it to “+63.”
Use the [SELECT </>] buttons to select the Filter Control pa-
rameter, then set the value with the [VALUE -/+] buttons or
data dial. Playing the Part at the minimum pedal position results
in mellow “lounge” piano sound; maximum position results in a
bright “rock’n’roll” piano.
Minimum position —
mellow sound.
Maximum position —
bright sound.
