I have just change my converters from a Tascams 1884 to and Aurora 8(with PT card) through a Digi HD1 Core PCI running from a magma 4 slot PCI to PcI e. I recorded flawlessly on my 1884 with out any latency at all. my chain being a simple one, mic-pre-tascam-daw-tascam. Now I use the tascam as a standalone mixer and controller for the cubase and the pt 8(HUI) while I use the digi core driver. What I am experiencing is a huge latency on the cubase 5 when monitoring input signals. I have changed the buffer size, but it doesn't do the trick. I wanna be able to use the digi core driver on cubase, because if I have to change to the tacams, I will have to reroute a lot of wiring. The PT8 works good with out any latency. Its eating my mind. I love the cubase, and I have adopted PT to compete on the market, as clients call for it. thanks for you time!!
