GI20Editor is a Roland GI-20 GK-MIDI guitar interface software editor, allowing user to modify any parameter, receive MIDI "bulk dump" containing device's settings, and send data back to the unit.

One of the convenient features of the GI20Editor is the ability to store a dump file of current settings and reload them essentially creating a backup. In this way, it saves time and makes the editing process less repetitive.
Within the software, MIDI repeater functionality is supported to run a hardware synthesizer, although it is not connected to the GI-20. Additionally, it has a small MIDI framework which makes it easy to use copy, paste and swap commands and duplicate or exchange entire patches.
In conclusion, if you are an owner of the Roland GI-20 GK-MIDI guitar interface, the GI20Editor offers you the chance to edit your device's settings with ease and save backups to avoid losing vital information with the added functionality of MIDI repeater support.
