Hi,

If you put the sample rate to 48Khz and make sure your using the Quattro ASIO drivers and not any of the Multimedia ones you can get the latency down about another 20ms or so.

There is so new BETA drivers for the Quattro on the M-audio website. They solved alot of dropout problems I had in FL Studio and Cubase SX, but I haven't had time to test on Pd yet.

Finally, if you build an interface for your patch in GriPD and turn off the Pd interface you can get the latency down to under 10ms. It's a little more work though.

So in general, is building an interface with GriPD a way to reduce latency? This is very interesting to me, as I am testing and trying to reduce latency on a few systems that I have running PD. thanks, David Merrill

That'll keep you occupied anyway!

Bye, epicSense.
