Roland GR-55 GK guitar synthesizer

Roland GR-55 GK

The Roland GR-55 is a revolution in guitar synthesis, with features never before available in any guitar processor. The GR-55’s powerful triple-core engine comprises two PCM synthesizers (with over 900 tones powered by the latest Roland synthesis technology) and COSM guitar modeling, featuring a virtual treasure trove of guitar, bass, amp, and synth models. Together, these combined technologies allow you to create unique, revolutionary sounds.
The GR-55 is far and away the fastest guitar synth ever. Furthermore, the COSM guitar-modeling engine needs zero detection time, allowing the GR-55 to respond instantly and exactly as you play.
The GR-55 is powerful yet extremely friendly. For customizing sounds, the EZ Edit feature (made famous in the GT-10) and large LCD takes the guesswork out of the process.
The GR-55 conveniently bridges the guitarist to the desktop music production world with its two USB ports. The rear-panel port can be used one for MIDI/Audio data communication; the side-panel port is dedicated to real-time playback of audio files from a USB memory device (sold separately).
