Just upgraded from 6.4 today. all seems fine, except when i opena song and select an instrument for the first time and try to play a note from my keyboard controller, there is a slight delay before i hear the sound (1/4 sec. maybe) - then it seems to sync up fine after that. this is happening with any instrument that i play for the first time (after opening the song). also if the song sits for a while, or i don't play a particular instrument for a while, then try to play it, I get the delay again. seems like a midi problem?? also there doesn't seem to be any delay ever if I just playback the midi tracks. anybody heard of this? thanks, mt G5 dual 2 gig 4 gig ram osx 10.3.8
