Simple Editing: Using A Controller - Yamaha SY77 Operating Manual

Many acoustic instruments allow the musician to modify the volume, tone, or pitch while a note is being
played. The SY77's controllers can be assigned to continuously affect various aspects of the sound for
musically expressive control.

Simple editing: using a controller

On instruments such as piano or organ, there is little that the musician can do to
modify the sound once the note has been struck. However on instruments such
as wind, brass; or strings, the volume, tone, or pitch can be continuously and
freely modified even while sound is being produced. The SY77's Controllers
(pitch and modulation wheels, aftertouch, optional foot controllers, etc.) can be
used to control various aspects of the sound over the duration of a note. This
allows the SY77 to be played with the musical expressiveness of an acoustic
instrument.
In the voice edit job directory, press
select 12:Cntrllr (controller). In this example, press F2 (Mod) to get the LFO
modulation controller assignment job.
Move the cursor to the Pitch row. Set Depth to its maximum value of 127 and
set 001 Modulation. With this setting, the
depth of pitch modulation over its full range. Move the
notice that vibrato deepens as you move the wheel forward. You will probably
find that when the wheel is fully forward, the effect is too extreme to be
musically useful. Decrease the Depth setting so that the full range of the wheel
is musically useful.
In this example, you assigned the
modulation, but any other controller could have been used instead. It is also
possible to assign two or more parameters to be regulated by the same
controller.
The controllers for pitch bend are fixed; the
keyboard, and aftertouch (pressing down on the keyboard after playing a note).
