A number of current PCI-based cards feature DSPs which can be used for the computation of VST effects in Logic Audio. Such cards include the TC Powercore (see upcoming review), Universal Audio UAD-1 and Creamware XTC.
Due to technical issues surrounding these devices and the PCI bus, an amount of latency is audible to the user, if the latency is not compensated. Emagic is currently working on a solution which will compensate for this latency, with the goal of making it inaudible. They anticipate that this solution will be included in a future Logic Audio 4.x sub-release (ETA - August 2001), which will be available as a free download.
