I have had problems with the UA-101 and Max/Msp on and off for a long time. Some time ago I thought i'd solved them when I updated to the new Edirol driver and the latest Max5 and they seemed to get along fine.

The cpu usage with the Edirol ASIO driver in Max5 is going through the roof doing simple stuff. Originally I thought maybe my patch was just badly designed, because the driver does work, its just that it peaks at 100% when asked to do anything remotely taxing (like granular synthesis with anything but tiny grains).

Now I discovered this was definitely a problem with the ASIO driver in Max5 when I ReWired Max5 to Renoise. As soon as I did that the CPU in Max5 dropped to 5% from 100%. Renoise was also using only 5% so it's not as though the workload was just shifted over to Renoise; I could do 10x as much work as max without the CPU maxing out and producing horrid popping noises or crashing it.

Currently I now *have* to ReWire Max5 to Renoise in order to use it at all without this problem.

Why is this happening? The Edirol UA-101 ASIO driver works perfectly with every other application I have but not Max/Msp.

Currently on Max 5.0.7, Windows XP, Edirol UA-101 Driver 1.0.3
