David,
I've been using SonicFire Pro for 2 years now - for every show I've made.
By my opinion - it is extremely flexible: length of music, how you could combine & "mesh" several melodies together, add extra sounds for effect, even take melody "apart" & create something new out of it.
... and
ONE huge PLUS: everything you will create out of it - is
ROYALTY FREE.
Here is the link: http://www.smartsound.com/index.html However - (my opinion again) - there are several conditions:
...- you have to own quite a number of SmartSound "Albums" - (usually 10-15 melodies in one album & about 5-10 variations for each melody) - to find melody to fit your show.
...- have "good" ear to recognize, what fits and what not.
...- & also (probably - why & what works in my case) - some basic music theory education or musical background, in order to be able to use & utilize the software fully.
For illustration - it would take me about 10-20 minutes to pick, adjust & create several (usually different length of music) variations for simple 60-90 seconds show. (But: shorter the show - more work on music it needs.)
