Hello Martin,

i'm copying this back to the list...
It seems that Logic cannot itself control the flow of MTC in any more
detail. Upon further inspection, i also start to doubt that there is any way
or need do that... because every bit of the MTC, including the quarter
frames, are necessary at the end.
This is the best explanation of MTC i've seen so far:

(Btw the whole web-site *was* nice and the Technical Docs section is
excellent.

So what i think you can do to reduce MTC traffic is that you reduce the
Frame Rate.
