This document is the Owner's Manual for the Roland GR-77B Guitar Synthesizer. It provides detailed instructions on the front and rear panel controls, including switches for Write, Copy, Tune, and various string modes, as well as pedals for Number, Bank, Cartridge, and Hold functions.
The manual details how to connect the unit to a Guitar Controller (using cable C-24G), amplifiers, mixers, and MIDI devices. It also explains the use of the Memory Cartridge M-16C and foot pedals for Pitch and VCF control. A specific section addresses problems caused by improper playing manner, such as sound delay, inability to mute strings, irrelevant sounds, and lack of sound, offering solutions for each.
| Product Type | Guitar Synthesizer |
|---|---|
| Memory Cartridge | M-16C |
| Guitar Controller Cable | C-24G |
| Pitch Control Pedal | FV-200 |
Sound delay occurs because the unit reads the waveform and detects pitch, which takes more time for lower tones (slower vibration).
The 3rd and 4th strings are likely to keep vibrating even when muted, especially during tremolo or repeat strokes.
Ensure the string is picked or touched hard enough, as pitch detection is difficult if the vibrating time is too short or the pitch is ambiguous.
