I forgot to answer this question from you. I basically find a preset that sounds close to what I want, then I tweak the hell out of. Often it ends up sounding nothing like the original. The samples are more or less factory, though, since I haven't gotten far in my sampling knowledge. As are the drums, as I've been really lazy with those - I'd really like to get to the point where the majority are coming from the Subtractor. (Electric Dayz, my first track, used all Subtractor percussion, but was pretty simplistic.)
I would definitely find a tutorial helpful. It's kinda cool that, when I'm in the mood, I'll browse around a little at the tips here and elsewhere, and usually find something useful that I would never have thought of.
Yeah, I play most of my melodies by hand, then tweak them in the piano roll. And when I want to create one grahically, I use the piano roll, because I find it gives me a great deal of editing flexibility.
Looks like a perfect controller keyboard. Must be nice to be able to tweak from there rather than with a mouse. My old Korg doesn't have the same communication with Reason.
I look forward to hearing what you come up with. Are you going to aim for trance?
