Easy Sound Editing

When you do venture into creating your own sounds the Roland GR-55GK makes things easy with EZ Edit. With the large LCD giving you a visual representation of what you’re doing, this feature, lifted from the GT-10, simplifies the process. It makes it easy to quickly access the parts of your sound you wish to alter, whilst leaving the rest unaffected, so you can sculpt your sound to the most finite degree.

USB Connectivity

Additionally the Roland GR-55 Guitar Synthesiser can be used with your computer via its two USB ports. One is set up for MIDI/Audio data communication, while the other allows a USB storage device to be plugged in, for real-time playback of audio files, which are controllable from the footswitch.
