Good afternoon, I just have a question about an old Mediavision Pro Audio Spectrum 16 sound card [rev. D] I'm using for my 486. I read online that it is possible to use a different Voyetra OPL-3 driver for Windows MIDI playback other than the one provided by mediavision themselves (SAPI!OPL.DRV is the driver in question that i'd like to use). However, I am having issues getting the 3rd party driver to work under windows 3.1, I just can't get the driver to appear under the midi mapper or under "drivers" whatsoever. I followed a guide that recommended copying the files manually & editing configuration files yourself. The reason I'd like to change drivers is so that I can enable midi playback using the OPL-3's 2 operator mode as opposed to it's OPM-like 4 operator mode, which it's currently stuck using under 3.1.

I have tried the compatible FM synth driver as well. It does work and it is recognized under 3.1, however the drum/percussion channel is incredibly quiet. For the record, the card doesn't appear to have any audible defects, and the Ad-lib compatibility works great under MS-DOS; sounds exactly like an OPL.

I am very new to MS-DOS and Windows 3.1, so the solution could be incredibly obvious and I may be overlooking something rather trivial. Any help would be greatly appreciated but I fully understand that you're kinda on your own to support yourself with this old sh*t. I'll continue to try my own solutions in my own time.

Thanks in advance for your help.
