For software, I would suggest looking at Harmony Assistant at
http://www.myriad-online.com.  It is shareware and available for
download at their site. It does not allow saving your work and
limits printing to one page until it is registered.  I don't have
MIDI gear yet, but I believe it allows recording from MIDI, and
controlling MIDI equipment.  The printed sheet music page looks
very good (and it prints street organ cards ready to punch!).
It's available for both PC and Macintosh too.

If it does the job, it might be worth the $65.00 registration fee.
