My CT3900 is too quiet with FM synth playing compared to AWE midi.
Tested mainly in Tyrian 2000's setup program where music plays all the time so it is easy to hear the difference.
Doom, Doom II has the same characteristics as Tyrian.

Jill Of the jungle and Prince of Persia both seem to be a bit louder so I am not sure if this is a card issue or that's the way those games are programmed.

UGH! is very quiet - even quieter than Tyrian, same for GODS' intro music.

Card is properly initialized, Mixerset is set to max under midi, master volume is at max as well, using line out output.
Part of the issue is that mixer has only one slider for midi volume which controls both FM synth and AWE midi.

I'm interested in other CT3900 users input on the matter.

Best,
Tym
