Hi Ken!
Try midish
http://caoua.org/midish
It installs a shell-like interface called "rmidish". If you're interested
in
a bit more comfortable shell (which might on occasions crash though, if you
harm it), I've written an alternative c++-version for the interface.
It supports only rawmidi devices (at the moment). But I found it to be
accurate. I even got a small personal version of midish, which has VERY VERY
basic jack_transport support.
Kindest regards
Julien
