Virus Playback Issues

[swipes]

Hello,

I recently purchased a Virus TI Desktop. I use it with an Apogee Duet Audio Interface and a Mac that satisfies the TI's software requirements. Although I've been very happy with the sound of the Virus, I've been encountering some problems regarding playback. When I record some midi, the Virus will play it back with no problem a couple of times. After several playbacks the Virus will start making wierd sounds instead of the ones that it's asked to playback and will eventually stop to play anything back at all. It will show the sync error message and ask to hit stop and play to clear. However doing so doesn't fix the issue and the Virus continues to not play back any sounds at all.
The Virus will do the same thing on sounds that have an arpeggiator on them whereas it'll play back the sound up to the highest octave and then eventually not play anything at all. When this happens, the only way to get it to play the programmed sounds is to turn it off and back on. However, it has started to act up much faster recently even after a couple of playbacks. I've purchased the Virus about 2 weeks ago, I tried using a different USB cable, different USB port on the Mac, lowered the sample rate on the audio interface, nothing has helped.
The described problem happens while in multimode although I can hardly imagine that being the problem since the synth is able to handle 16 parts and I merely have 3 parts playing back simultaneously as of now.
I'm assuming it has something to do with the USB connection or the software itself. Help would be much appreciated since you can imagine that it's impossible to have a proper workflow when I have to keep turning it off and back on for it to work.

Thanks!
