midish can't be MMC slave (i.e. it ignores start/stop/relocate). If
your hardware has an MTC source as well, you could setup midish to
follow the MTC clock and the effect would be the same.

This makes midish follow sndiod's MTC clock (i.e. it syncs to audio
programs). As sndiod can be MMC slave, just send the MMC messages
to snd/0 with another program.

Just make sure audio programs (if any) use a sndiod sub-device with
MIDI control enabled (-t slave option)
