I've had pretty good luck with "Melody Assistant" from MYRIAD Software (France).

It's not perfect, and has some irritating little quirks, but at $15 to register after a free trialware download, ye can't go too far wrong! "Melody" has a lot of the sophisticated audio gimcracks you mention above, way more than I have a clue what to do with them, and has been said by some who apparantly know that it compares favorably with some of the more upscale programs costing in the $300 range.

I like the feature of being able to pirate a MIDI file off of the web, have this put it up as a score for me to transpose (into a whistle or fife key, for instance), arrange, edit, print, record, and/or send to a chum as a *JPEG file if they don't have the program. I have gotten regular free upgrades for over a year now and excellent tech support.

MYRIAD also has a music score scanning program kind of like musical OCR called "OmER" which is intriguing, but I've never been able to get it to work very well. I'm hoping that they will eventually get it fixed.

For a free download, It's gotta be worth a try, eh? Let me know how ye like it!
