Well, no I didn't, but what would be the point? At the end it would need to have the whole buffer for the audio interface anyway. From the positions it looks like one thread is always ahead, so this would actually higher the latency, woudn't it?

have you verified that the other instances are not actually processing
data for the future? Logic has some fairly hairy capabilities in this
respect, and you cannot assume that every track is computing data
"just in time". I don't recall the terminology for sure, but it might
be something like the "current focus track". i seem to recall that
this track will process data with a different buffer size, to provide
lower latency while doing GUI manipulation.
