I wonder if Jan Hammer really composed it specifically for the MT-32, or if he used a better device and someone at Sierra just converted it to MT-32.
Long time, no post.. You and me both

I think you're right. I highly doubt Hammer composed and MIDI-fied the score (any composer at Sierra could use custom SysEx). Looking at Moby, credited to 'Sound' is:
Sound Robert Atesalp, Mark Seibert
I doubt those two just did SFX. Look at Atesalp on Sorcerian, he didn't compose anything, he took music and used some awesome custom SysEx patches to make a neat MT-32-ified score. Seibert could have done about anything on it.
Much more likely is like with GK1, where Robert Holmes composed most of the music but didn't know how to do the PC-side of it, and the Sierra music team (Atesalp/etc) MIDI-fied it and altered it slightly and added some extra pieces in.
It's also interesting to note that some of the pieces in PQ3 are actually MT-32 translations of some Miami Vice instrumental music, the Crack House (or is it the burning building? I forget) being such an example (season 1 episode.. 7 I think? I can check).
It's been a loooong time since I played the 3rd PQ game. probably because DOSBox wasn't around for a while and the driving in XP kills you.
Guess I should say which I like better. It's really hard, but I think I prefer PQ2's theme.. just. If you look at the start of both pieces, they start off very strongly. THe middle of the PQ3 intro sequence (with the echo pan or whatever it is, I forget!) is a little repetitive and boring for me (although I like the progression), whereas with the PQ2 intro, it always has that drum and bass beat. I guess I felt for the intro, PQ3 needed more of the punchy intro that it had, and less synthy meanderings. And I feel that way about a few parts of PQ3's score, although don't get me wrong, JH is a synth god.
For the record, I like PQ1VGA's intro better than either of the other two
