Virus TI extreme sync problems

[prinsnilsson]

Hi!

My Virus TI Polar goes out of sync all the time and the BPM led light is always slightly ahead of Logic Pro 8.0.1, making the sound always being slightly ahead as well making it unusable as TI plugin. The whole idea of buying a TI was to make it TOTALLY INTEGRATED with my production. Now I mainly just use it as an old fashioned hardware synth but I don't wanna accept that anymore so I decided I wanted to solve this matter since I have read nowhere else about these exact problems. Have a listen to an mp3 that I recorded: mp3
It's about 150kb to download. I used an external mic in the room. I was playing back a song and also had the Klick running to be able to judge the extreme sync problems.
I have set the midi clock on the TI to external btw.
I'm using:

TI POLAR 2.5.1 OS (via USB)
Mac Pro 2.66 GHz
6 GB RAM
OS X 10.4.11
Logic Pro 8.0.1
Apogee Duet

Anyone have any clues?

Thanks,
Mathias Nilsson

I also have the same prob. After leaving the TI on idle for a while (about 12 hours), the bpm clock is lost, same as the LED.
The way I get around it, is by putting the TI to sleep and wake it. The clock is back again and the good thing is that, any patch changes aren't lost, so a dump can be quickly done.
Good luck

Thanks.
The issue was solved by the Access support (thanks guys!). I was using "Large" in the "process buffer range" selection in Logic, it should always be set to "Small" when using the Virus as a plug-in. It solved the whole thing.
