"Unnoticeable" latency usually refers to the musician not noticing the
difference in time between when they press the key and when the sound
comes out. Any time you add a delayed signal to the original signal, you
will notice it. The "slap-back" happens at longer latencies, but at
shorter latencies you will hear *very* noticeable comb-filtering. And
since no computer-based solution is latency-free, I think you need to
re-examine what you are expecting Pd to do. Either that, or go with a
dedicated DSP board (and learn the accompanying programming!) which
would give you a more guitar-pedal-like "zero-latency" system.
Maybe Marco Donnarumma could give a few words here on processing
instruments live. His set uses an electric bass through Pd. My guess is
that even the un-processed signal goes through Pd to avoid echos or comb
filtering due to latency.
Best,
Derek

* in terms of processor capacity, hardware, and sound card
configuration, what would be the minimum requirements to achieve
unnoticeable latency (not hear the affected signal as a slap-back
type of effect)? i've read that 11ms can be achieved and is
unnoticeable.
