Well I discovered that the metronome must be set to a MIDI port of some kind before any MIDI clocks will be sent. That seems like a bug... what does MIDI clock have to do with metronome?

A few other things:

- Sometimes when starting rosegarden, it complains about a missing MIDI device (they are all there) and then segfaults. It then seems to load some kind of autosave file, but it doesn't have the last saved state of the actual file I want.

- Audio clips don't start when the transport is rewound and then played... it is necessary to press play and then rewind.

Overall I really want to like and use Rosegarden, but it seems very fragile and so far just setting up a few MIDI and audio tracks and configuring my studio's MIDI devices has led me to what seems like a broken file which I can't load anymore.

Are people actually using this successfully with multiple external MIDI devices? Is there any way to debug things when a file doesn't load? I tried using gdb to check a stacktrace but I don't think I'm familiar enough with the codebase to really know what's going on.

The UI of rosegarden is as close to my dream app as I can imagine... simple, great notation editing, audio and MIDI recording... but if I'm worried that I won't be able to reload the file I'm working on, it's unfortunately not that useful. :(


Cheers,

Andrew

Thanks for the info. I checked aconnect and sync out seems to be
connected to every MIDI device, even ones that are not set up in
rosegarden. (my sound interface has a port which I don't use... it's
assigned)

But when I start and stop I can see that a port sends START, Song
Position, and STOP, but never sends any ticks. I viewed the data with
MIDI-OX on another computer.

Are you sure MIDI-OX is not filtering out the ticks which are generally hiding
the useful data the monitor is recording ?

Here is the output of RG seen by a tiny MIDI monitor coming as a test of the
RtMidi API ( free online bettinghttps://www.openhub.net/p/rtmidi ) and which can be easily
compiled (I'm currently unable to compile Kmidimon on my new computer :-( ).

$ ./cmidiin

Would you like to open a virtual input port? [y/N] y

248 is the decimal value of the timing clock MIDI code.


Are there any other kind of settings I need to make?

Currently I can't imagine any other setting.

It would also be
nice if it wouldn't connect up non-related MIDI devices since I do other
MIDI things on my computer which might be upset by receiving useless
clock messages.


As Michael said, connecting/disconnecting with aconnect, qjackctl or some
other tool should be the better solution.
