MIDI SPP and MIDI Clock are unrelated to MMC.
it is not possible to interpet either of them without tempo/meter
information - they do not refer to an audio-based timeline, only a
"musical time" (bars|beats|ticks).

they are not divided from each other. JACK MIDI is a cleaner API and
allows much simpler sharing of MIDI data between audio applications. the
fact that few apps directly support it at present isn't very significant
since you can bridge from ALSA to JACK MIDI and back again.
that said, i do think its a little odd to make this utility connect to
JACK MIDI. any JACK MIDI client sending MMC to do transport control is
just being stupid - it can control the transport directly. the
interesting cases all involve the MMC source outside the computer, which
makes using ALSA MIDI directly a bit more sensible (IMHO).
