How to use use hardware MIDI (oss or alsa) in SDL_Mixer

Is there any way to do this? Several games I’ve tried (most recently, the
icculus ROTT port) have MIDI music, but it won’t work unless I’ve
installed SDL_Mixer with the Timidity patches, as well as Timidity

I have a SB Live with hardware MIDI, and I have OSS sequencer and ALSA
sequencer support. The MIDI music from these sounds better than from the
software wavetable version. Can I use the hardware instead?
