I don't, it was just for testing out the hypothesis I thought would explain why I was getting bad timing. I have just been testing it again, and I actually think the problem was in Yoshimi. Sorry for making Jack Midi sound bad :| Running dino and yoshimi (both jack midi apps) the timing was bad even with decent low latency (and then yoshimi zombified) but using phasex - not a jack midi app (is it?) - (still with dino) the timing was near perfect. And thanks Paul for your answers too.
