MU128 Guided Tour
The actual, physical means of controlling (such as foot pedals, modulation
wheels, etc. on a connected keyboard) are generally assigned to specific
“virtual” control numbers. A few examples of these include the modulation
wheel (at control number 1), foot controller (control number 4), and volume
pedal (control number 7).*
Control Numbers and the Actual Sound
The control numbers described above are in turn assigned to some specific
aspect of the sound on the connected tone generator (for example, to vol-
ume, pitch modulation, dry/wet balance of an effect, etc.). As you might
expect, control number 7 (Volume) affects the volume of the connected tone
generator.
In this example, the foot controller of a keyboard controls the volume on the MU128.
Assignable Controller (AC1)
* On some instruments, the control number for the physical controllers
is fixed; some instruments allow you to assign a different control
number to the existing control. (Refer to the owner’s manual of your
instrument for details. Also for more on control numbers, see the
“Sound List & MIDI Data” booklet.)
