I noticed a post about this software but the poster mentioned that she hadn't "really used it." I'm wondering if anyone has tried this GM software with a Vista or XP pc and what they think of the sound quality compared to the VSC-3 and other VSTis? I am seriously considerig buying it as the latency seems to be low and the sound quality of these demos seems good. The videos in French but the music is all that matters http://en.woodbrass.com/PRODIPE+VE+USB+VIRTUAL+EXPANDER+AND+SOUNDCARD I don't think it can be as good as Ketron SD2 but I am still very interested.
