Re: [Linuxsampler-devel] profiling, etc.

[Garett S. <shu...@co...>]

Hello, I checked out the cvs a few minutes ago and am getting a 
compilation error (last few lines of build posted below. I have tried 
-march=athlon -mcpu=athlon as well as the default i686 ). I have a copy 
that I checked out on the 5th of December which builds and works pretty 
well (nice work!). I am running an athlon xp 1700 with the 2.4.27 kernel 
which has been patched with low latency and kernel preemption (is this 
similar to what others are running?). Also, I think there might be a bug 
with the amplitude for voices that are triggerd by release velocity. The 
gig patches that have  release voices play these voices very loudly when 
I trigger them on my keyboard. -Garett
