Yes, I'm running ASIO4ALL V2 also.



Just upgraded to v2.10, no change. Still ends with memory access error in amplitube 3.vpa.

Check above, my post about resetting the cache size.



I set disk cache to max. no change.

**ALSO - if your machine is running any kind of Power Saving, whether laptop or not, that should be turned OFF in Control Panel. Especially any of those schemes that ramp the CPU processing up and down to conserve power. They simply can't respond fast enough for this kind of work.



Thanks. I always turn off all power saving features because of the potential problems. I also turned off all unnecessary screen animations etc. to no effect.

The problem still seems to be in amplitube. The system is reading an invalid address in amplitube 3.vpa. Maybe someone from PGM might have some ideas if they see this. Also, I may contact support later when I have the time.

Thanks Mac.
