I've got this strange situation. I have to configure a PC with Xp and a M-Audio audiophile card and Reason. When i set the buffers at 128 all is fine. No latency. I let the Pc sit for one hour and try the controller keyboard again. Bang! The latency is unbelieveable, like 1 second! So i quit Reason and start it up again. Voila no latency. Let it sit for a while and the latency increases again. What is happening here?
