in addition I also noticed best to turn of ramp emulation in ff7music, since that can cause sound to cutout on some fmv's.
covarr, I guess that depends on the quality of soundfont banks used on the pc alongside the soundcard.
On a decent creative card its possible to make the supplied pc midi sound as good if not better than the ps music. My original motivation for using ff7music was I was playing ff7 on my laptop onboard realtek sound.
I am back on my desktop pc now but have decided to keep using ff7music as it allows me to use some crysis core and remixed music.
