When
controlling
Timbre

make
settings in
the
Sound
Patch
to specify control
nimibers
for
the parameters.
Be
sure
to
use
control
numbers
other
than
the three
shown
above.
When
controlling external
MIDI
devices,
remember
than
the control
numbers
that
can be
received (and the
result
they
will
have)
will differ
for
each
device.
Consult the
MIDI

for
each
