Patch going out of tune!

[simog]

Hi all,

Came across a rather infuriating issue while laying down the final parts to a track I need to send off.... One of the patches I was using kept going out of tune!!

The patch was Chapel MS (under pads) and there was no automation on the track. This was through VC and I was routing the output to USB2 L+R so I could side chain it independantly. To describe the problem, it sounded like one of the parts to the patch was being slightly pitched up randomly.

It was playing absolutely fine to start with, but later on in the evening, after about 4-5 hours use it began to exhibit this behavior. Most annoying as I was at the mix down stage!

Anyone have similar issues? If so is there a fix?

I am running OS 3.0.3 on the Virus TI2 Kbd

Thanks,

Simon
