I didn't know where to post this, so I'm posting it here. It wouldn't fit very well in modding section, I believe, since it's not really a mod...
Anyway, I had some problems with MIDI playback in OpenXCom, but I really like how my SB Audigy handles those files and I just couldn't find a good enough replacement, even though there are many music packs available. Pack converted using "MS_GS_WVTB.sf2" seemed to be the closest one to what I was used to hear, but well... it sounds awful to be honest.
Therefore, I recorded my own pack from original MIDI files using my SB Audigy card. It sounds much better than the stuff created with sound fonts, at least IMO. I made it mainly for myself, but maybe some other people will like it and find it useful.
Tracks were cut in Audacity, so they should loop nicely, although I didn't test it in-game yet. Also, I didn't adjust the volume - just recorded it as it is - so if some tracks should be played louder/quieter please let me know.
