  • Patch dumps cannot be initiated with the “Fetch” button in the app, but are reported to work when initiated on the Virus TI. You can do this in the “Save”-menu by choosing the save-option: ‘patch dump’.

Please feel free to send me a note with your USB to MIDI interface and how it works, so I can keep this list updated.
