Using
Controllers
While
playing,
you
can use
the
EXT,
Ci and C2
controUers
to adjust the value
of
timbre and
effect
parameters.
The Keyboard
Patch
will convert
controller
movements
into
MIDI
control
change
data.
For
each
Sound
Patch,
you
can
specify three control change numbers, and
specify
the parameter
to
be
controlled
by
each.
It
is
also possible to use
these
controllers to
control
external
MIDI
devices, or to control Timbre and
Effect
parameters from an
external MIDI
device.
