With the synchron-ized products there is no problem at all, it's only with Synchron Strings I. The problem has always been existing since the first release of Synchron Player.
I confirm this, but just for the sake of clarity, it seems that there were a few happy versions of SY Player that didn't have this problem. Unfortunately, I don't have the version 1.0.1076 mentioned in this thread. @Paul, is there a way to put SY Player 1.0.1076 into MyVSL downloads somehow? The version in "downloads archive" (1.0.1141) is affected, too.
P.S. I doubt it's the HDD/SSD thing, because the problem is reproducible when playing a MIDI clip in a loop, when all the samples are already loaded (I checked hardware usage during the dropouts, there's nothing going on with either disk or CPU).
