Some people can’t get the “TI” part of the Virus TI to work properly on their computers. For me, I just like using them as external synths to avoid the large latency they incur when in TI mode. For these reasons I’ve made a MidNam file for the Snow. Although I don’t think the patch names have ever changed, this MidNam is written against OS 4.5.3.
UPDATE: It seems to still be valid for OS5.
