Hello. I have encounter a few issues with Multiface II. I play .WAV files in Cubase and Ozone 6, sometime the pitch change drastically (1/2 tone or so). The Multiface is the master clock at 44.1, my XL-48 preamp is plug to the Multiface with the ADAT connection. I use Windows 7 64 bit and the latest driver for the Multiface. Any ideas what cause this ?
