(Diva) Static on eighth voice

[ghunter]

I've just loaded up Diva 32-bit into Ohm Studio and I'm getting static whenever I hit the eighth voice of preset "HS High StraDIVAri". It doesn't seem to do this with other patches.

Here are my system specs:

Windows 7 Professional X64
Asus N53SV Notebook w/ core i7 2630 QM & 12 GB RAM
Focusrite Scarlett 2i2 USB 2.0 interface (using ASIO driver)

I have tried this in Divine and Great modes with buffer sizes between 64 and 4096. It seems to get worse with the 4096 setting (clipping on the third sometimes fourth note) but all other buffer sizes reliably have noise on the eighth note.

Has anyone else seen this?

Updates:

I'm running the latest version of Diva, Rev 903.

The problem goes away when I select "multi-threaded"
