Re: [Rosegarden-user] a few newbie questions

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


A few other things:

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

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

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

Are people actually using this successfully with multiple external MIDIdevices? Is there any way to debug things when a file doesn't load? Itried using gdb to check a stacktrace but I don't think I'm familiarenough 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'mworried that I won't be able to reload the file I'm working on, it'sunfortunately 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 ( https://www.openhub.net/p/rtmidi ) and which can be easily
compiled (I'm currently unable to compile Kmidimon on my new computer :-( ).

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.
