DP and spinning beachball

[audiobrad]

In an effort to reduce latency with virtual instruments in DP, we tried lowering buffer settings to 128 or 256, but when we do this we get the spinning beachball. So we're stuck at 512 which is too slow for live playing of instruments.

Oddly enough, if we switch from Digi HD hardware to the G5's internal audio, we can lower the buffer down to 64!

Anyone know what causes this?

Have you done the upgrade to DP4.52 (released yesterday)? It's supposed to handle virtual instruments a lot better. I have only played with it a bit, but it seemed much more responsive with Mach 5 than the first DP 4.5 release on my Mix3 system.

Thanks Traks. I'll check it out. Anyone else re: the spinning ball? What does this generally mean. RAM allocation problem?
