I haven't used mine with a midi guitar so I'm not sure which settings you would need. If you go to www.synthzone.com you will see a list of different manufacturer's. Go to Korg and then scroll down to the X5 sites. They have alot a info on some (Korgy Park for one). They might be able to help. X5 Banks has alot of new banks ( I think around 30) so you can download thousands of new patches. If I come across any info I'll let you know.
