When the "send MIDI clock and system messages" box is checked, I've noticed 
that Rosegarden (a July CVS version) sends a stream of song position 
pointers, and no start, stop or continue messages at all.

I always thought (and I could easily be wrong), that the proper way to use 
MIDI realtime/system messages,  was to send a single song position pointer, 
followed by a continue message, and then use MIDI clock messages to conduct 
the synchronization during playback.

I took a look around the web, and the second-hand MIDI descriptions I read 
were all kind of vague about whether it's allowed to use song postion pointer 
as a synchronization device during playback. 

I personally have no problem with it, except for this - using thie technique, 
how do I know when playback has stopped or started, since Rosegarden isn't 
sending the start/continue/stop messages? (Or maybe it is, and my MIDI parser 
is loosing them). I think the only way is to use a timeout technique - if I 
don't receive a song position pointer after a timeout period, I consider 
playback to be stopped, until the next spp is received. Is this the way to do 
it?

Or is this behavior a bug and I should get the latest CVS (yeah I know I 
should but want to make sure audio is working before I bother)

Thanks in advance
