Introduction; Main Features - Roland GR-20 Owner's Manual

Introduction

The GR-20 is a guitar synthesizer (guitar synth) which contains a high-quality sound generator and is
designed for easy operation.
The GR-20 carefully analyses the pitch and volume of each string as it tracks the signals being output by the
divided pickup (a pickup installed on your guitar which outputs a separate signal for each string), and uses
this information to trigger its built-in sound generator. At the same time, a data stream interpreting your
guitar performance can also be transmitted via the MIDI OUT connector, and used to play an external MIDI
device, such as a sound module.

Main Features

• You can play more than 450 different types of synth sounds in the same way as when playing your guitar
conventionally.
• In addition to playing the synth sounds by themselves, you can combine the normal guitar sound with the
synth sound.
• When applying an external effects unit to the normal guitar sound, you can use the Mix In jack to mix the
processed sound with the synth sound.
• The GR-20 can be used with any steel-string guitar on which a GK-3 or GK-2A (divided pickup; sold
separately) can be correctly installed.
• The GR-20 can also be used with a bass guitar on which a GK-3B or GK-2B (divided pickup for bass guitar;
sold separately) is installed.
• Built-in effects (reverb, delay, chorus) are provided for the synth sound, creating a rich and spacious
ambiance. (p. 20)
• You can adjust and store settings such as attack and decay time, and effect depth. (p. 20)
• You can use the GR-20's two foot pedals to apply a Hold effect or Glide effect. (p. 15)
• Use the built-in expression pedal to control parameters such as volume or filter. (p. 16)
• Since your guitar performance is output as MIDI data, you can use your guitar to play an external sound
module or as an input device for your MIDI sequencer. (p. 28)
• A guitar tuner is built-in for quick and accurate tuning. (p. 13)
