 By using jack_capture instead of ecasound, this should be enough:

 jack_capture --jack-transport
 jack-smf-player -n foo.mid &
 sleep 5
 echo locate 0 | jack_transport
 echo play | jack_transport 
 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
