Actually it was the SBPro 2.0 that had an opl3, the original sbpro had the opl2 still. So, to my understanding, the game had 3 different sounding sets of music: - opl2 (adlib/soundblaster), in the *.hsq files - opl3 (adlib gold only), in the *.agd files - MT32 (roland mt-32?), in the *.m32 files That dune midi player application uses regular adlib/sb opl2 too. Now, is there any way to play the opl3 *.agd files on a ver 2 soundblaster pro that has the opl3 YMF262 chip on it? I happen to have a card like that, and I'd really want to know how the opl3 differs in sound quality. I tried exchanging the *.agd files with the *.hsq ones and launching the game in soundblaster mode, but it only had notable differences in two tracks, and even those were more like missing instruments (MORNING and SEKENCE, going by the names the dune midi player uses). also first post, hello, etc.
