I tried some more programs and for now I am most pleased with these two:
MIDPAK, by John W. Ratcliff.
The full package can be found on the internet as Dmkit150.zip. It contains a lot of files all thrown in a single folder, drivers for all kinds of soundcards. Together with John Miles variants these drivers where behind the audio output of many commercial games.
Anyway Midpak's Menu.exe is a nice midi player, and with Setm.exe you can select between opl-3 or general midi or PC-speaker etc. For Opl-3 output it uses fat.opl as an instrument bank, which is designed by the 'Fat Man' as to resemble general midi instruments. I attached to this post the files necessary for using menu.exe as described.
GSPLAY v1.0 by Mark Fontana. The second program that impressed me today: Good interface (customized text mode), worked instantly, well documented, no-nonsense, single executable... Search for GSPLAY1.ZIP.

GSPLAY is a Standard MIDI File player for IBM-compatible computers
running MSDOS. The program has been specially designed for playing
General MIDI and Roland GS Standard MIDI files, but it will work fine
for non-GM/GS files as well. GSPLAY also includes special support for
the Roland SC-88.
