I've worked with many free online midi files to create backing tracks for myself - usually using the bassline & maybe the main chords to work from.
For the most part, they are horrible: terrible horrible arrangements, very bad timing, and often layers and layers of general midi information that has to be stripped out to be able to use the song at all.
In any case, a tremendous amount of work is required to get anything decent, much less "studio quality" sound. This applies to pop music, and is often worse in the classical realm, especially in the matter of tempo.
I usually ended up hiring a musician to create the needed files for me. Or buying a version from a reputable online midi store (who pay royalties I'm fairly certain). Now mostly doing originals, so point is moot.
