Muse was one of the programs I considered when looking into downloadable (?) software to change tunes into sheet music. My decision was to go with ABC2Win. It can be found at:http://www.execpc.com/~jimvint/
The program is easy to use (obviously, it *must* be for me to be using it!) You can download it free, and to have printing capabilities it's very minimal ($20).
I have had a blast searching the web for tunes (in abc format) that I have been wanting to learn. I find a collection of tunes or an individual tune, and download it into the ABC2Win (easy as pie - - no, easier than that....easy as cobbler...) and from there, I can slow it down, speed it up, manipulate it so I can learn it easily. My favorite site for finding tunes used to be at (I wish I could that cool trick where you just "HERE" in hypertext and it links you there, but ...):
http://www.gre.ac.uk/~c.walshaw/abc/index/wwabc.html
Here you'll find a llllooooooonnnnnnnnngggggggg list of tunes in alphabetical order and takes a long time for the page to load, but it's a comprehensive list of tunes. However, since Alice mentioned this site in a different thread:
http://minya.ne.mediaone.net/~jc/music/abc/FindTune.html
I have been going there, typing in the name of the tune I'm seeking, finding the tunes in gif (sheet music) form and just hitting my print button.
I hope this information is within the scope of the what you were seeking Mick.
