The VG-8 / VG-88 V-Guitar is not a guitar synthesizer like the GR-09, GR-1 or GR-30/33, or a Guitar-to-MIDI Converter like the GI-10. In the GR-Series and the GI-10, the signal from the GK-2A pickup (which is analogous to a standard pickup signal for each string) is converted to a pitch which is then available to trigger a sound, either internally (GR-09, GR-1, GR-30) or through MIDI. This makes these units ideal for sequencing and playing realistic sounds like pianos, organs or drums.
On the VG-8 / VG-88, the signal from the GK-2A is modified in real-time into an entirely new sound which allows all of your picking and playing techniques to be preserved. The VG-8/ VG-88 does not transmit MIDI note numbers, nor does it act as a MIDI sound module. Although the VG-8 / VG-88 has the ability to modify the guitar sound into unique sounds (like a synthesizer would), there is absolutely none of the tracking delay normally associated with guitar synths because the sound of the guitar is modified in real time. The VG-8 / VG-88 is unsurpassed in creating a multitude of authentic guitar tones which would previously only be attainable by purchasing a truckload of different guitars, amps and speakers.
