GI20Editor is a software editor for the Roland GI-20 GK-MIDI guitar interface.

Besides being the only alternative to programming the device through a knob, a two digit display and a few buttons, GI20Editor can greatly enhance the guitar/synthesizer connection experienced through the GI-20.

A detailed manual and a demo version are available at


• clear and easy access to all the GI-20 parameters

• save complete GI-20 setups as documents, for backup purposes and fast switching between different configurations

• import and export of GI-20 dump files

• patch related copy, paste and swap commands, plus a powerful 'paste special' function to apply only selected changes, possibly extending them to all patches at once

• direct connection to a MIDI synthesizer

• on-the-fly substitution of GI-20 bank/program messages to allow rapid testing of different sounds without the need of a “bulk load”

• optional MIDI system exclusive, bank/program change and control change messages sent at patch selection

• string grouping options for faster editing

• MIDI remote control


Release Notes:

• the app is sandboxed

• each patch can send up to 8 user defined MIDI Control Change messages for each string/channel to the “synthesizer output” device

• small user interface improvements
