Main Features Sound: Sophisticated fusion of a PCM synthesizer and COSM modeling sound generator Sounds produced by a high-quality PCM synthesizer and a realistic COSM modeling sound generator can be freely combined to take advantage of each method’s unique characteristics. You can intuitively create new sound combinations with a high degree of freedom. For example, you could create a new lead guitar sound that’s based on a standard distorted guitar combined with a synth lead or organ.
Settings This chapter explains how to make the necessary settings when using the GR-55 for the first time. First, get your guitar/bass ready • In order to use the GR-55, you’ll need a guitar or bass equipped with a divided pickup (GK pickup), which outputs a separate signal for each string. You can use GK pickups such as the Roland GK-3 or GK-3B. • For details on how to install a GK pickup, refer to the owner’s manual that came with your GK pickup.
Preparations for Using the GR-55 Connections Guitar equipped with a GK-3/ GK-2A, bass equipped with a GK-3B/GK-2B, or a commercially available GK-ready guitar or bass Amp or PA (line) The GUITAR OUT jack outputs the sound of the normal pickups and the sound of the modeling tone (p. 22). For details, refer to “GUITAR OUT Jack Settings (GUITAR OUT)” (p. 54). If you’re using monaural output, connect only to the L/MONO jack.
Preparations for Using the GR-55 Selecting Guitar or Bass (GUITAR<->BASS) Adjusting the Pickups (GK SETTING) To ensure that the GR-55 is in the best possible playing condition, please make the appropriate adjustments for the divided pickup (GK settings). Making these settings will ensure that the GR-55 is operating optimally. Before you use the GR-55, you must make a mode setting that specifies whether you’re using it with a guitar or with a bass.

How the GR-55 Works What is a Patch? A “patch” is a unit of sound on the GR-55. In addition to settings determining the type of sound, a patch also contains effect settings. You can modify (edit) the settings of a patch, and save it as a “user patch.” (The patches already built into the GR-55 are called “preset patches.”) The following illustration shows how a patch is structured internally. PATCH Effects Synthesizer sound These effects processors apply various effects to the sound.
Editing the Tones (TONE) As shown in the illustration below, a GR-55 patch consists of several tones. You can create a new patch by selecting different tones or by editing the detailed settings of each tone. PATCH PCM TONE 1 Synthesizer sound PCM TONE 2 This is a synthesizer sound that plays according to the performance data from your guitar. Two tones can be layered. MODELING TONE Modeling sound This is a modeled sound based on the audio from each guitar string. Changing the Tone 1. 2.
