Any guitarist can play the GR-300, using all standard guitar playing techniques, including: hammering, glissandos, harmonics, chopping, etc. The GR-300 produces effects and nuances which keyboard synthesizers cannot easily produce. In order to use the GR-300 Guitar Synthesizer unit you must have a Roland compatible guitar controller such as the G-303 or G-808 with the divided HEX pickup installed.
To produce the effect of the GR-300, you would need: 6-octave shifters + 6-com pressors + 6-chorus machines + 6-distortion units + 6-phase shifters + waw + etc. + etc It is very easy to produce anything from simple or complex solo sounds to the sounds of a huge band or orchestra. All major functions are controlled with foot switches and require no hands.
Small, compact unit (like an effects box) with all electronic- type foot-controlled switching of major functions; good for live perform- ance. Produces stable effects for all styles of guitar playing which, up to now, were impossible: hammering, glissando, chopping, etc. Totally polyphonic: one VCO for each string. Instant and accurate transposing to two preset pitches. Duet switch for chorus effect. Polyphonic distortion for new clarity, even with chords.
