I also had jack_capture in mind first, it always stopped though whenever
a sleep command finished that had been issued after it. Thus, being
lazy, I used something else instead of investigating this.
It turns out that jack_capture's --no-stdin option does the magic.
That's interesting. Maybe it has something to do with the piping.
Another alternative would be to open
jack_capture in a new terminal. Then you also
avoid cluttering the terminal with text output
from both jack_capture and jack-smf-player:
xterm -e jack_capture --jack-transport &
jack-smf-player -n foo.mid &
sleep 5
echo locate 0 | jack_transport
echo play | jack_transport
