usual function but are merely used to define which sound, belonging to the Preset, is to
be edited. Once the sound is selected, the display shows the number of the corresponding
sound or shows the wording "oFF" if the sound involved is not used in the preset
(muted).
• Select the sound to be added to the Preset using the value +/- keys. A total of 512 sounds
are available and their names are written in Appendix A of this manual.
The parameters of the GM sound can be edited using the numerical keypad combined with
the value +/- keys. Each number of the numerical keypad does indeed match an editable
parameter. Hold one of the numbers down and the display will first show a 3-letter initial
that points out which parameter is being edited, then after a few seconds it will show the
related value.
• To change the volume of the sound, hold key 1 down. The display will show "VOL" and then
the value of the volume currently set.
Edit the value using the value +/- keys (range 0-63).
• To change the shift in semi-tones of the sound, hold key 2 down. The display will show
"SHF" and then the value currently set.
Edit the value using the value +/- keys (range -24 +24).
• To change the pitch of the sound (tune), hold key 3 down. The display will show "TUN" and
then the value currently set. Change the value using the value +/- keys (range -64 +63).
• To change the stereo panning of the sound (pan), hold key 4 down. The display will
show "pan" and then the value currently set. Edit the value using the value +/- keys
(range L64 R63). Letter "C" stands for Centre.
• To change the operating range of the sound (left/right range), press key 5. The first
time you press it, the display shows "leF" (Left Range) and then the note. The second
time you press it, the display shows "rIg" (Right Range) and then the note. The key codes
can be entered either using the value +/- keys or by pressing the relative keys on a MIDI
Master keyboard connected to input mIdI In2. Press the value +/- keys simultaneously
and the range parameter is set in "oFF" in order to disable the range limit (Left or Right)
of the sound.
• To change the dynamic operating range of the sound (low/high velocity), press key 6.
The first time you press it, the display shows "low" (Low Velocity) and then the value set.
The second time you press it, the display shows "hIg" (High Velocity) and then the value
set. The set values are changed using the value +/- keys.
• To change the reverb amount of the sound, hold key 6 down. The display shows "rev"
and then the value set. Change the value using the value +/- keys (range 0 - 63).
• To change the type of effect applied to the sound, press key 7. The display shows "eFF"
and then the type of effect set. You select just one effect for each Preset. The options
available for this parameter are:
o "OFF": No effect
o "CHO": Chorus
o "DIS": Distorsor
o "DEL": Delay
o "SLO": Leslie Slow
o "FAS": Leslie Fast.
