I have recently compiled and installed ecamegapedal

post my questions to this list as I'm assuming Kai Vehmanen subscribes to
this list as well.
You assumed right. :)
First off, ecamegapedal is exactly what I am looking
for - an easy way to turn
a computer into an effects box. Realtime reverb, delay, LAPSPA plugins...
Also check out JACK-Rack:

First is that I'm getting a lot of backround
distortion/ static. I can hear my
input signal fine and the selected effects work as they should. The level
meters are quite active when there is no signal input/ quiet passage and the
distortion is a low level buzzing/ static that is totally related to running
the program.
Does the same happen with ecasound? Here's a few things to try:
# basic ecamegapedal style rule
ecasound -i alsa,default -o alsa,default
# ...the same but with an effect
ecasound -i alsa,default -o alsa,default -pn:time_phaser1
# ...more buffering
ecasound -i alsa,default -o alsa,default -pn:time_phaser1 -z:intbuf
# ... 8bit only
ecasound -f:8,2,44100 -i alsa,default -o alsa,default -pn:time_phaser1 -z:intbuf
# ... use ALSA hw-interface
ecasound -f:8,2,44100 -i alsa,hw:0 -o alsa,hw:0
... you can also try running both as root and as normal user, and see if
there is any difference.
The other problem is periodically the computer totally
locks up, GUI, mouse,
keyboard, everything freezes and I have to do a hard reset (no other program
that I've run seems to cause this on my computer but the computer is old and
flakey in other respects...).
Hmm, running as root...?
Creative SB AWE64 ISA soundcard
Now this is problematic. I have one and it is a pretty lousy card
unfortunately. :( For example, you cannot do simultaneous 16bit playback
and recording. One of the streams has to be 8bit.
