That's correct mate. I love Rock and Metal and I use Cakewalk for my guitar backing tracks. I choose famous classical songs and create Metal Versions out of them. I'm finishing Hungarian Dance No5 now, a very fast (140 bpm) 2/4 classical masterpeice. I'll upload the finished MIDI soon for everyone to give it a try* or, even better, tweak it a little. I believe the best way to learn guitar is to play classical songs. Much better than boring scales and repetitive exersices.
BTW I watched your video. Very informative. You should make more of these .
* I use MT-PowerDrum kit and a Standard Bass for the tune.
