Roland Polyphonic GR-300 - STRING SELECTOR; DISTORTION

STRING SELECTOR
When using the guitar and synthesizer sounds
simultaneously (Guitar Controller BALANCE
control somewhere near center), the STRING
SELECT switches can be used to determine
which strings are to produce the synthesizer
sounds. There are six switches, one for each
string. Only those switches that are ON will
produce synthesizer sounds. These switches
can be used where it is desired to play a melody
Or a bass line against guitar chords, for example,
or for other effects where the synthesizer notes
are to be relatively independent of the guitar
notes.
DISTORTION
There is one more switch on the Guitar Con-
troller left to be explained. With this switch at
the VCO position (pointing towards the bridge),
the VCO synthesizer sound is produced. When
changed to point in the opposite direction, the
HEXA-DISTORTION effect is produced. At
center, both synthesizer and distortion sounds
are produced.
The GR-300 distortion is different from ordinary
guitar distortion in that there is a separate dis-
tortion circuit for each of the six guitar strings
thus producing an unusually clear distortion
effect even when chords are played. This sound
is also passed through the VCF where the tone
color can be further processed. Try the VCO
DISTORTION sound.

The STRING SELECT switches affect only

A foot switch can be used with the STRING

between the condition set with the STRING
SELECT switches, or all strings ON.
