none of these.
second problem arose recently: "tempocalibration" In playback some instruments (it differs from piece to piece) are not just on time on the beat: they come some microseconds later, or don't follow the drumpart. I hear "padam" in stead of "bam" if you know what I mean. very annoying.

sometimes older scores (all made in sib.7.5) I reopen to edit don't playback, altough the screen show sound were loading up at opening the score. in best case 1 instrument is sounding. restarting the computer doesn't help, restarting the configuration doesn't help.
what went wrong?
