Interesting. So using the same SCC-1, I'll get better MIDI music from the DOS version vs. the "Extended MIDI" Windows 3.1 MPC version? Why is that?
Actually both Basic and Extended means reduced channel usage compared to Full GM /GS compatible 16 channels. Basic uses only 4 channels (13-16) and Extended uses only 10 channels (1-10). GM compatible hardware can use both Basic and Extended and also could use the 3rd Full 16-channel option if the games had one (but apparently not).

If the DOS versions use full 16 channel MIDI that could sound better on your card.
Also besides reduced/more optimal channel usage neither Basic nor Extended has any special property that makes them more appropriate for FM or Roland or Turtle Beach gear. E. g. SB 16 or any other OPL3 FM synth can use not only Extended but also Full 16 channel setup. The installation program of SB 16 actually really creates all the above 3 (Basic , Extended, Full) Midi mapper entries.

Basic/Extended is only really useful for OPL2 and MT-32 compatible synths. GM/GS compatible and even not GM compatible but 16-channel capable synths have no reason to use either Basic or Extended setup.

Also contrary what you believe the above games have no special support for your Turtle Beach MultiSound Classic sound card's MIDI. They use your card just like any other cards that have an installed Midi driver under Windows. It depends on the Midi mapper settings if your gear sounds good or bad.
These games use the standardized Windows MM API and Windows Midi Mapper that are both hardware agnostic from the perspective of the application.
