wow... just found out about this topic, and way too advanced. I'm also a Sierra-fan games and its music (played almost all of them i think), plus I have learned lots about MIDI thanks to QuestStudios back in '97. It's just too bad that until now I still haven't got the chance to enjoy true MIDI qualities from Roland cards since they's still expensive and rare. Well I'm just grateful that QS offers the mastered tracks in digital format and boy, they do sound much more realistics than ever.
I even have tried to play back those games using DOSBOX emulator that has Roland enhanced driver (not the common DOSBOX emus) and still hasn't got to hear the exact qualities as the one produced by QS.
But even that, Adlib was still quite good MIDI counterparts and I agreed that synths were made separately for each sound driver to match each own qualities. And I have a good quality time listening to them while playing over and over again until digital musics (Audio tracks, MP3s, etc) starts to take over the market. Btw, one of these great examples was found in games like Conquest of Camelot.
oh... I'm also from INA.
Jam it back in, in the dark.
