Details

timidity can't use jack devices (using the -Oj flag):

$ timidity -Oj -iA
jack_client_new: deprecated
TiMidity starting in ALSA server mode
Opening sequencer port: 129:0 129:1 129:2 129:3
Couldn't start JACK device (`j')

(the last line of output happens when any MIDI device is connected to timidity, e.g. via qjackctl or rosegarden, no sound is produced even though it would with -Os [ALSA output])
Also I had the same result with both jack and jack2.
This task depends upon

could this be the solution: http://blog.163.com/jiams_wang/blog/static/3033914920138120746567 ? (edit: the change does not compile with the 2.14.0 tarball)

changing (lines 269 and 285 of jack_a.c)
jack_client_new(TIMIDITY_JACK_CLIENT_NAME)
to
jack_client_open(TIMIDITY_JACK_CLIENT_NAME, (jack_options_t)0, NULL)
fixes the deprecated message, but not the issue

finally, this makes it work (at least with the 2.14.0 tarball, i don't know how this bug originally came into existence):
add
case PM_REQ_PLAY_START:
in jack_a.c, line 511 ("fall-through")
this constant seems to originate from alsaseq_c.c, line 549.
(traced the error message in gdb with "b fputs")
The blog entry http://blog.163.com/jiams_wang/blog/static/3033914920138120746567 uses wrong/other constant names for some reason.

Playing midi files works over jack, the bug only appears when using -iA -Oj (alsa-sequencer).

@jmb: My bad. I tested integration with jack and thought this was not relevant anymore. Maybe not thoroughly enough.

It seems that as of today upstream has not fixed this: https://sourceforge.net/p/timidity/git/ci/master/tree/timidity/jack_a.c

I'll release a new version of the package soon.
