I find this very hard to believe, is this just because you are
auditioning
your realtime input directly through the sound card? Because no
software
can process audio input and output a modified version without
latency. Try
playing through a plugin in realtime in protools or dp, I suspect
you will
notice a latency. If not, maybe you should be translating your pd
patches
into audio unit plugins, but I strongly suspect you will notice a
latency.
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.
20ms * 343m/s = 7.546m
So if you are 7.5m away from one of your band mates, there will 20ms
of latency just from the sound travelling thru the air.

@Justin Glenn Smith: Do you have links or names of some of that
measuring software you referered to? That, I really like to try out.
