Chapter 5 Setting/Changing Sounds (Patches)
Dividing Continuous Pitch Changes into Semitones (CHROMATIC)The GR-33 faithfully reproduces the slight pitch changes and
in-between notes you get from fingering your guitar’s
strings.
However, should the need arise, you can also limit this subtle
pitch response to semitone changes only. This is called the
Chromatic function, and is turned on and off using the
COMMON “CHROMATIC” setting in Patch Edit mode.

■Turning the Chromatic Function On and Off
and Saving It to Patches
1. Select the patch you want to change, and press
[COMMON] to go into Patch Edit mode.
2. Press [PARAMETER] to select “CHROMATIC.”

3. Turn [VALUE] to select the desired setting.
* For a detailed explanation, see the subsequent section,
“Chromatic Settings and Available Effects.”
4. Press [WRITE] to perform the Patch Write operation (p.
36).
* After performing the Patch Write operation, you will
automatically return to Play mode.
* If you don’t want to save the Patch, press [PLAY] to return to
Play mode.
◆ Chromatic Settings and Available Effects
Off (Chromatic Off):
For guitar bending and vibrato, this setting allows you to
make synth sounds faithfully reproduce subtle played pitch
changes of less than a semitone.
When you select any setting other than Off, pitch changes are
limited to semitones.
Type1:
If the pitch is changed smoothly, for example by bending the
guitar string, the pitch will change in semitone steps. When
the pitch changes, the currently-heard sound will not stop; it
will merely change in pitch. There is no separate attack
sound when the pitch changes—this is a change similar to
the one you hear with the slurred playing of a recorder.
Type2:
If the pitch is changed smoothly, the pitch will change in
semitone steps. When the pitch changes, the sound for the
new pitch will be started over, or “retriggered.” Thus,
whenever the pitch changes, you will hear a new attack. If
the retrigger occurs as a string’s vibration is trailing off
(decaying), the retriggered note will play at an appropriately
reduced volume.
Type3:
This is basically the same effect as “Type2,” except that the
retriggered sound level is not influenced by the current state
of the string’s vibration.
When You Want to Make a
Chord Resonate Beautifully
Due to subtle pitch changes resulting from the way each
string is pressed, with patches using long notes, chords may
end up sounding muddy. If this occurs, turn Chromatic on so
that only pure semitones are heard, thus producing a
beautifully in-tune chord. If you select “Type1,” pitch
differences will be barely audible, creating a natural-
sounding resonance.
When You Want to Reproduce
Piano-like Pitch Changes
In patches that emulate instruments which do not use pitch
changes smaller than a semitone, Chromatic allows you to
more easily imitate the instrument’s sound. In such cases,
when “Type2” or “Type3” is selected, the attack is
reproduced with each pitch change. (Depending on the tone
or melody, there may be times when “Type1” or Off” yield a
better effect, so select the setting you like best.)
