GI20Editor for Mac2.1

11 January 2013

Software editor for the Roland GI-20 GK-MIDI guitar interface.

What is GI20Editor for Mac

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 simplify the guitar/synthesizer connection experienced through the GI-20.


  • 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 GI-20 dump files.
  • Patch related copy, paste and swap commands.
  • Direct connection to a MIDI synthesizer.
  • MIDI remote control.
  • On-the-fly substitution of GI-20 bank/program messages, to allow rapid testing of different sounds without the need of a "bulk load".
  • String grouping options for faster editing.
  • Powerful "paste special" function to apply only selected changes, possibly extending them to all patches at once.
  • Optional MIDI system exclusive and bank/program change messages sent at patch selection, to properly setup the synthesizer.
  • Up to 8 user defined MIDI Control Change messages for each string/channel for each patch can be sent to the "synthesizer output" device when a patch is selected or in real time.

What's new in GI20Editor

Version 2.1:
  • 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.
