Yes! Guitar Pro MIDI export, and import works just fine :)
I exported the beat I made in Guitar Pro a week ago.
When imported in another DAW (Reaper in this case) and loaded in a drum VST, it works (almost) perfectly.
In this case I loaded the BATTERY VST.
Unfortunately, the deeper kick drum and some other misc. elements wont play unless you assign a sample in that octave range. But basically it works like a charm :)
The only thing i haven't figured out yet is how to import an audio file to Guitar pro, that sucks big time, as I can't comp the melody directly in the program.
If you have some other beat making DAW's, please leave your comments, also I'm interested in glitch and break-beat VST's.
