Take 3.25m and 10ms, then its more scale, I was just going with the 20ms number. Then you can look at the latency in many physical, traditional instruments like the violin and there is probably more than 20ms between action and sound. .hc On Oct 20, 2009, at 4:12 AM, hard off wrote:

There is no audio software without latency.  The lowest that is feasible on Mac OS X is probably 4ms.   Once you factor in distance and speed of sound, then you might see that 20ms of latency isn't really all that much. Yeah, sorry that I said there was no latency, I do know that every

I have quite the same setup and goal for pd. I play my guitar through a pd patch and would also like the latency to be as low as possible. I've come as low as 11ms in the pd settings, with my Macbook (white 2007) OS X 10.5, Jackpilot and through my Digidesign Mbox 2 or MAudio Fast Track Pro

SNAP. Maybe try using Jack? (if you're not already) It should save you a little CPU overhead, which might allow lower latency. Nick On Oct 16, 2009, at 7:22 AM, babsyco babsyco wrote: Hi guys-I just have another fairly simple question. I'm running PD on a macbook pro with a 2.26 Intel
