OpenBSD has a aucat utility that can play/record files in sync with
midi, but it requires parts of the openbsd sound sub-system.
There's a Linux port of the whole thing here:

http://www.sndio.org/install.html

Basically there's a small daemon that forwards synchronisation
messages and keeps audio programs in sync. It's documented and easy
to use, but configuring the OpenBSD audio bits on Linux may not be
trivial as all this is relatively new on Linux; let me know if you
want the full reciepe to make it work.

There are attemps to make jack use MMC for control and expose clock
source as MTC, but I don't know how well this works; here's the
discussion about it:
