what is ams ? just try to search about that with no luck...

Ok, to begin I tried to use 3 instances of Jack rack but the resulting sound is very bad ; there is a lot of saturation even if no effects are loaded !
Sometimes effect plug-ins are jumping so I must restart all the apps and reconnect all the stuff in order to get the chain working again, I can't imagine doing this during a live session :)
This configuration doesn't seem to be really stable :-(
I turned myself to Linux in order to find a stable config :)


So as suggested by other people, I tried ecasound :
when I run it in interactive mode and I set the input it complains with
a seg fault :-(
Anybody could help me with ecasound ?

I'm on demudi 1.2.0 with Kernel 2.4.25-1-multimedia-686
motherboard P4PE PIV 2.66GHz 512ko cache with 512Mo of DDRAM
the sound device is an integrated analog device soundmax (snd-intel8x0)
I have an edirol UM2 midi interface (2 in + 2 out)
all devices seems to be well controlled by the system.

thanks a lot

Philippe
