Ok, from what I understand, this is just a utility to run simulations correct? Or do I need to tweak this for optimal performance? I use a firepod and I thought you control buffer sizes through the firepod driver? Am I doing something wrong? Reason I ask is from reading this thread: (Dead Link Removed)#182937 So do any of the values I change in ASIO Multimedia Setup Utility effect what is going on in Cubase? I especially don't understand the number of buffers set to 5 and DMA. Anyone an expect and can clarify these things? :?
