Download GI20Editor

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. It can also save a dump to a file and reload it, thus allowing backups. As far as I know, this is the only available editor for the GI-20.

It should be really easy to use, just a few things:

Of course you need to have your GI-20 connected to your PC through a MIDI interface or a USB port.

To receive and send data you need to select your MIDI input and output devices: use the "MIDI/Setup..." command for this.

If you connected your GI-20 through USB, you will tipically see a "Roland GI-20 MIDI IN" input device and a "Roland GI-20 MIDI OUT" output device.

You will need to do this only once if you don't change your setup, since your choices are stored in the "GI20Editor.xml" preferences file.

If the chosen devices are unavailable when you start GI20Editor, their name will be shown in red instead of green.

Receiving a "bulk dump" is automatic. Use the "MIDI/Upload bulk..." command to send data back to the GI-20. See the GI-20 manual to learn how to send and receive a bulk dump.

You can use the "Edit/Copy patch" and "Edit/Paste patch" commands to easily duplicate patches.

You can click on the patch number to quickly select another patch.
