It is indeed true that JACK MIDI is "intended to extend/replace the ALSA sequencer". The problems addressed by ALSA's sequencer API are, so the JACK MIDI crew claim, better solved in user space in a manner substantially similar to the way that JACK MIDI attempts to solve them. I personally believe that the existence of the ALSA sequencer API is just a result of a combination of the limits of (and ignorance about the possibilities of) the Linux 2.2 kernel. If you don't believe you can do realtime stuff in user space (which arguably was true in 2.2), then of course you put something like ALSA sequencer in the kernel.

ALSA sequencer.

"The short answer:
Jack-Midi has been introduced to extend/replace alsa-midi
[...]
They currently co-exist."
Looks like somebody dreaming of world domination.
