About the Guitar Synthesizer
The GR-33 guitar synthesizer, though small and compact, is
big on functions and high-quality sounds.

Say “synthesizer,” and people generally think of the typical
kind with a keyboard controller. However, since the keys on
a keyboard synthesizer are in essence simply advanced
versions of basic on/off switches, synthesizers cannot really
offer a faithful expression of strings or wind instruments.

On the other hand, with the guitar, the part of the instrument
that actually vibrates (i.e. the string) is touched directly. As a
result it excels in the expressive power that arises from slight
changes in pitch—changes even smaller than a semitone—or
vibrato or muting. And because guitars are easy to play,
there are more people playing guitars than keyboards.

With these points in mind, the guitar synthesizer was
developed as an instrument that, while played like a guitar,
could be used for sound generation much like other
synthesizers.

The guitar synthesizer is set up with separate pickups for
each of the guitar’s metal strings. These pickups register and
send the frequency and amplitude information in each
strings’s vibration to the synthesizer, which then in turn
expresses the data as pitch, volume, and tone.

generator) via the MIDI OUT connector, you can also export
guitar performance data while simultaneously playing the
instrument’s internal sound generator.

instruments, and so on—in an instant, without
physically changing instruments.

When properly installed, the GK-2A divided pickup

guitar strung with metal strings.

●
Not only can you layer two synthesizer tones—and
freely assign sounds to each string—you can also store
fine adjustments to such settings as brightness and
attack. You can also store differences between the pitch
of the guitar and the synthesizer sounds (p. 49–52).

With the Synth Harmonist function, you can add
beautiful synthesizer harmonies—in keys you select—
to guitar sounds or to synth sounds (p. 80).

By applying effects (reverb, chorus and multi-effects)
to a synthesizer sound, you can make it even richer and

You can use a variety of panning effects: use two
different synth sounds in stereo, or spread out the six
guitar string sounds from left to right, placing each
sound in its ideal stereo location, and so on (p. 41).

By recording your playing into a MIDI sequencer, you
can create realistic plucked stringed instrument
sounds—something that keyboards just can not do as
easily—adding greater expression to melody parts (p.
93).
