Hey fellas!
I am having problems with syncing seq24. As soon as I choose any JACK
Transport option for it, it stops playing. I tried restarting it, I tired
various combinations of those options so that seq24 will even start
Hydrogen, but it will not send midi itself.
Any advice?

I am using Ubuntu and I am using KX Studio repos. What package should I
look for? Because
I am sure I got seq24 from kxstudio!

Looks like it!
There are updated packages available for KXStudio, you're using Ubuntu
right?

Louigi, Jeremy, could you tell me when you succeed with this patched seq24 and recent
jack1 versions? Last time I tried
it didn't work for me. Maybe I'm wrong but if I understood correctly, recent jack1
transport no longer goes into Jack_Transport_Starting state before going to
Jack_Transport_Rolling (this was deliberately dropped), but seq24 currently needs this to
start off with jack transport.
Cheers

I did not revert to jack1, but I am using a fixed version. I have no desire
to revert to jack1 just to fix seq24, especially that you say it still does
not work :)
Is there anyone working on seq24 these days?

Hm jack transport+seq24 in jack2 works for me even without the process_callback
modification. Not your case?
Is there anyone working on seq24 these days?
I don't think so....which is very unfortunate, some time ago there was a nice team
gathering around the project though.

Non-sequencer has more future imo, new version is on it's way. It's
gonna be nice I think.

what leads you to make this claim?
nothing has been changed in jack1 transport in a VERY LONG time.
http://jackaudio.org/files/docs/html/transport-design.html
the docs say:
The engine handles polling of slow-sync clients. When someone calls
jack_transport_start()<http://jackaudio.org/files/docs/html/group__Trans…af>,
the engine resets the poll bits and changes to a new state,
JackTransportStarting<http://jackaudio.org/files/docs/html/transport_8h.…ac>.
The *sync_callback* function for each slow-sync client will be invoked in
the JACK process thread while the transport is starting. If it has not
already done so, the client needs to initiate a seek to reach the starting
position. The *sync_callback* returns false until the seek completes and
the client is ready to play. When all slow-sync clients are ready, the
state changes to
JackTransportRolling<http://jackaudio.org/files/docs/html/transport_8h.h…
.
and also:
These request a new transport position. They can be called at any time
by any client. Even the timebase master must use them. If the request is
valid, it goes into effect in two process cycles. If there are slow-sync
clients and the transport is already rolling, it will enter the
JackTransportStarting<http://jackaudio.org/files/docs/html/transport_8h.…
and begin invoking their
*sync_callbacks* until ready.

OK so this is clearly my bad. The reason for this 'claim' is a discussion on
seq24-devel ml between Torben Hohn and Guido Scholz about future versions of jack, in
which the sync callback in seq24 should be dropped, because it will no longer work. I may
have misunderstood parts of it. The other reason is that when I tested it with jack1
(quite some time ago) seq24 didn't respond to jack transport start, and I didn't
see it going into the transport_starting state. So the above came from that, and now I
know I made a false conclusion, but I don't think I dreamed it.
Sorry then
Frank

In my case look up the message that started this thread - I am using fixed
version of seq24, yet it does not play midi. It can start Slave apps.

Hello Frank,
I'm using Jack1 0.121.3 and don't recall having issues with Jack
Transport and a patched version of seq24.
