I want to report the same issue. When I have attempted to use this program with an AWE32, Orpheus, and Pro Audio Spectrum 16 all in OPL3 FM and the music sounds off. Like Nitroraptor stated above. The instruments are off and sound completely different then what would sound in game.

Also tried on 2 different DOS era computers.

I'm not sure if Mateusz is still here on Vogons at all so I try to answer your question instead of him:
The point is you should not expect OPL3 output to sound the same as in games. Most games that use FM synthesis (OPL2/3) for music do not use Midi at all for OPL music or have their own default instrument set.
DOSMid has its own default instrument set and you cannot expect it to be the same as your game has. But you can load another instrument set for DOSMid if you have the proper one for your game by using the /sbnk=FILE command line switch.
This can work for games that use Midi also for OPL music internally (such as Duke3D) but not for games that program the OPL directly for music (such as Dune).
The .MID files that you can download for the games from the internet are not made for OPL but for Roland MT-32/Roland SC-55 and similar GM devices.

PS:
If you want to hear the exact same OPL sound as games output it you should download VGM files instead of MID and use SBVGM for DOS:
SBVGM (DOS) VGM Player
VGM files preserve the exact commands sent to the sound chip so playback results in sample accurate sound.
You can download VGM files from here ( search for OPL2/3 also known as YM3812/YMF262 ):

Thank you for your time and responding Falconsoft! I appreciate the info as well as your software as well. Looks like VGMRIPs is down at the moment, but I will look into it. I have been trying to record different game music outputs and wanted to do OPL3 next. It is interesting that in say Windows 3.1. I can have proper FM play through these MIDI files but then a program like DOSMID96 does not. Just trying to figure it all out. Thank you again.

FYI: The Windows 3.1/9x default OPL 2/3 driver uses the so called 'Fat-Man' instrument set. DosMid definitely does not use this. The Fat-Man set is the one older Windows users heard the most so it sounds as 'the normal' for most of us.
But if you listen carefully and compare in game sound in Doom, Duke3d etc. to Windows 3.1 playing the same game's Midi files you should definitely hear the differences.

I will check it out when I can. Going to have to setup a 486 test bench soon as I am trying to get some captures off of a Pro Audio 16. Thank you again for all the insight. Always learn a ton when reading on here.
