I know your pain with Guitar Pro and Midi
Since Most of my songs are tabbed through GP5, and it's in midi, I feel your pain. This is very good, I can work on the drums for you if you want. And you can maybe give the guitar track (with tabs) to you're favorite guitar artist on here.
Or if you want, PM me, give me the track, and I will work on the drum track for you :). No problemo, well maybe not, because I have soooo many requests to do. But I will work on it for you if you want.
Over all good work.
-Your fellow Midi user and hater :)
