Although I've spoken to tech support at MOTU and they're working on it, I thought I'd post here to see if anyone else had experienced the same problem.
I installed MOTU Symphonic Instrument on my PC (P4 3.2 Ghz - 1.5 Gb RAM - Windows XP Pro) and when I call up the VST or DXI plugins in Sonar 4 SE the instruments have a loud staticky "buzz" to them. None of my other VSTs have ever given me this problem (GPO, EWQLSO, Colossus, SampleTank, etc.). I'm using an external Edirol SD-90 as my USB audio interface. I don't see anywhere on the plug-in itself where one might change buffer settings or anything like that so I don't know what to do. I guess I've been lucky in that this is the first time any VST plugin has ever given me a problem. Any advice would be greatly appreciated. Thanks.
BTW - I tried uninstalling and reinstalling but still no luck.
