It's been a while since I've used any Windows music software but I don't remember getting on too well with Noteworthy. I seem to remember thinking Melody Assistant preferable.

For my own needs at the time though which were trying to have fun with midi once in a while and occasionally providing a missing MIDI for Mudcat, I found an early (2.0?) version of Cakewalk I'd got from somewhere, a much better fit.
