GI20Editor screenshotGI20Editor is an utility for the Roland GI-20 GK-MIDI interface that will let you easily change all system patches and parameters. The program lets you save entire GI-20 setups as documents and allows you to easily switch between various configurations. You can also import GI-20 dump files.

GI20Editor allows you to use various commands (copy, swap, paste) in order to exchange or duplicate entire patches. You can also use the “Paste Special” command that will let you apply only a certain group of parameters and extend them to all patches at the same time.

GI20Editor provides improved synthesizer control, allowing you to easily define exclusive system messages that can be sent to patch selection in order to set up the target synthesizer properly. The application lets you send a maximum of 8 midi control messages for each string and patch. The messages can be sent in real time or when a certain patch is selected.

GI20Editor allows you to test various sounds without uploading changes to your GI-20 unit by using on-the-fly replacements of various GI-20 bank/program messages. The program lets you define maximum 3 different strings groups and automatically apply string parameter changes to all the strings found in the same group.

GI20Editor also lets you choose patches or send control change messages to your synthesizer using an external midi controller.


  • Lets you control your synthesizer using an external midi controller.
  • Lets you test various sounds without uploading changes to your GI-20 unit.
