that's correct. qtractor mmc-locate resolution is crippled to 30fps 
since eh... ever? :)

yes (or no:) qtractor does not send out any mmc-locate messages on its 
loop turnarounds. sorry. thinking of it, i am not sure whether that is a 
polite thing to do. let me think again...

aha. it brings me down to this humble fact that qtractor mmc 
implementation is no substitute for jack-transport whatsoever...

have you tried jackctlmmc? or is it qjackmcc? hmm, i don't quite 
remember... my aging memory is failing on the spot:)
