Just wondering on what people think of composing with styles. When I compose music, I usually play in all the parts on the sequencer, but have thought of creating my own backing as a style file so it would be all orignal. I just wondering if anyone else does this?

Also another question, if I used a Drum pattern from say, a Yamaha style, and used it in one of my compositions, would this be copyrighted?

Cheers
