Roland GR-700 Owner's Manual page 21

The GR-700 digitally processes the vibra-
tion of the strings producing digital
signal that controls each section of the
synthesizer. This is in other words, even
the string vibration inaudible in usual
guitar performance is processed. There-
fore you may be annoyed by unexpected
reaction of the guitar when playing. The
following are the possible symptoms and
the reasons.
1, Unstable Pitch
eYou have played a long tone with
high fret, which causes very weak
string vibration.
@ Right after muting.
eYou have played in
technique.
Harmonics
2. Correct Pitch is not obtained.
@\n playing quick phrase, the string is
picked before it touches a fret.
e@You have picked the string too hard
in Harmonics technique.
@You have played in Harmonics tech-
nique,
3. Sound cannot be muted
@ You have played Tremolo or a quick
phrase with the 5th and 6th strings.
(These strings are likely to retain
vibrations longer)
@®You have repeated an open chord or
a muteless stroke.
4. Irrelevant sound is heard
@You have touched or picked un-
necessary string. (In usual guitar
playing, it would not be audible.)
5. The sound is not heard
e@The vibrating time is short and the
pitch is ambiguous.
e@ You have not touched or picked the
string hard enough.
PIf you are using the Guiter Controller
other than the GR-700, the above
matters may be more notable.
pTo play in chromatic, A=440Hz tuning
should be strictly observed.
