"Driving the synthesizer is like playing the guitar" GR-300 is a new type of polyphonic guitar synthesizer, different from an ordinary guitar synthesizer. It can be used to syn thesize as easily as playing an ordinary electric guitar. First of all, it has an outstanding express ing ability, being able to reproduce the subtleness of the guitar sound which cannot be obtained by a keyboard synthesizer. Secondly, it is equipped with HEXA VC0 and HEXA distortion circuits which means a clean distortion can be obtained, like GR-100, Furthermore, it is equipped with advanced features such as Envelope Follower and polyphonic VCO Sweep. It is a compact guitar synthesizer especially suitable for live performance.

"HEXA VCO and string vibrations them ~lves duet by using pitch shift'' ~R-300 is equipped with a PITCH SHIFT tunction capable of master tuning, which is tuning the pitch of the HEXA VCO inside the unit to the pitch of the string vibrations of the guitar controller. You can also preset the pitch of the HEXA VCO (pitch A, pitch B) within a range of +1300 cent and create a duet with the string vibrations of the same pitch. It covers a range from one octave below to one octave above the original note, and by using it along with the duet sound, you can get octave sounds, 3rd and 5th harmo nies, and other chorus effects.

"Rise time and fall time'' The Rise Time and Fall Time controls set on the HEXA VCO shifts the pitch when switching between Pitch A and Pitch B. The portamento is 0 at minimum, and a longer portamento time can be obtained by turning the knob fowards maximum. To get a bending effect, set the Rise Time and Fall Time at a high level. When gliding, set Pitch A (B) a half note away from the normal sound and change the switch to "unlatch".

"String selector" Numbers 1 to 6 on the panel refers to the six strings. Only the strings turned "ON'' will produce a VCO sound. You can enjoy solo work by turning on the higher strings and emphasize the high tone qualities, or for bass work, turn on the lower strings. You can also enjoy mixing it with the guitar sound, using the Balance control on the guitar controller.
