Analogue-sequencer

OK, this could be me, but I can't get Mackie Tracktion (a software DAW) 
to control my P3 sequencer.

Tracktion appears to be sending something out of its ports, but it 
doesn't seem right.

The P3 starts on time, but then its own clock is the determining timer 
and not Tracktion's. The two machines go quickly out of time with each 
other. Also, on pressing stop, Tracktion stops, but the P3 continues on 
at its own tempo.

Looking at the midi stream out of Tracktion with midi-ox I can see a 
'continue' signal sent when start is pressed in Tracktion. Shouldn't 
this be seen as a 'start' not 'continue'. Then a series of timing pulses 
which possibly are correct, but the fact that the P3 runs on its own 
tempo is very odd.

On pressing stop in Tracktion there is no stop command but the timing 
pulses do stop.

Now I thought the timing pulses should be present all the time, and 
start and stop commands should be sent by Tracktion only.

So is it Tracktion at fault, or have I got some weirdy with my 
system/understanding of midiclock.
