Have been experiencing some latency issues with Cubase SX 5 of late, both MIDI and audio:
When i start a project, the latency is fine. However, as I slowly add more tracks, suddenly the latency becomes bad. When this happens, I try removing plug ins, vst instruments, and even whole channels to see what is causing it, but no joy. In fact, I deleted everything from a project but the same problem occurs.
I am using an audiophile 2495, and the M Audio Asia Drivers.
