hi all,
i'm working on my sampler proggy, but it seems to be cutting out
at about 15 or 17 polyphony. i've got a pII 400, and i know you can get
many more voices (i think giga sampler can go to 64 on this setup).
compiling with pgcc -O6 gives me 1 or two more voices.
i was under the impression (although possibly influenced from work
on other processors), that floating point was pretty much as fast as
integer math on most modern processors, and the only thing that kills you
is float to int conversions. how accurate is that?
my design isn't exactly optimized, but i'd like to get some idea
of what avenues would be the most productive to persue: what has been
everyones experience as far as getting performance out of their designs?
thanks,
rob
