I'm not sure, if you know about the virtual midi devices which can be used
like the ordinary rawmidi devices, but the midi stream is parsed to the
sequencer events and versa vice. The virtual midi device behaves like a
sequencer port, so you may connect it to other ports (like the wavetable
sythesizers or midi uart drivers). So far, no changes are needed on your
side. You must only use the ALSA rawmidi devices instead of OSS ones.

Anyway, we can copy our MIDI parser code from the kernel to the user space
and create nice MIDI stream <-> ALSA sequencer converter. It's nothing
complicated for us and it seems that it helps a lot to you. It'll allow
use more features of the ALSA sequencer.
