GI20Editor is a software editor for the Roland GI-20 GK-MIDI guitar interface. It can receive a MIDI "bulk dump" containing all the current settings from the device, show and modify any parameter and finally send data back to the unit.

In addition, this application will also be able to save a dump to a file then reload it, thus enabling you to make backups.

To begin, click the "Set devices..." button in the "MIDI" page to inform the editor about the kind of connections you are using (MIDI or USB). Your choices will be stored in a "GI20Editor.xml" preferences file, next to the application executable. If the chosen devices are unavailable when you start GI20Editor, their name will be shown in red instead of green. When the GI-20 receives MIDI messages through a MIDI cable, selecting a patch in the editor will select the same patch on the GI-20.

Requirements:
* GI-20 connected to your PC through a MIDI interface or a USB port
