Roland GR-33 Guitar Synthesizer

   (0 reviews)

The GR-33 is an affordable floor-based guitar synth featuring an upgraded sound engine, new effects, improved tracking speed and a streamlined user interface with built-in expression pedal. With a sound architecture equivalent to Roland's acclaimed JV-1080 synthesizer module, this GK-Ready synth is capable of producing some of the richest, most interesting sounds and synth effects in the history of guitar.

Floor-based guitar synth with 384 stunning instrument sounds

Sound source derived from the industry-standard Roland JV-1080 synth module

Ultra-fast triggering with any steel-string guitar via user-installable GK-2A Divided Pickup (sold separately)

Dedicated Chorus and Reverb processing, plus 40 multi-effects including rotary, overdrive, etc.

Synth Harmonist feature adds "intelligent" harmony to a single note

Output Select switch permits use with conventional guitar amps or power amps

Assignable expression pedal and onboard arpeggiator

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 ~he 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. By connecting an external MIDI device (e.g. another sound generator) via the MIDI OUT connector, you can also export guitar performance data while simultaneously playing the instrument's internal sound generator.
