Here, by the way, is the crossover_3chan contents:

nano 2.6.2 File: crossover_3chan

#!/bin/sh

export LADSPA_PATH=/usr/local/lib/ladspa:/usr/lib/ladspa;

# -a:woofer2 -pf:./woofer.ecp -chorder:0,0,0,0,0,0,1,2 \

-a:woofer,mid,tweeter -z:mixmode,sum -z:nodb -B:rtlowlatency -b:64 -f:f32_le,6,48000 -o:jack

I've discovered that if I invoke this script using the /usr/local/bin path by just typing crossover_3chan, it also does not work - apparently b/c it is being run or owned by "root" instead of gibbyj. I.e., if I run it from /home/gibbyj/Downloads it works, but if I type "crossover_3chan" from some other directory, and it finds the script in /usr/local/bin, it shows up in ps -aux with "root", and it doesn't work. But when I boot the computer, it's not even sbowing up in ps -aux, with root OR gibbyj...

Thanks again...

Hi,
I'm getting my Pianoteq app to run automatically when I start my computer. So far, I'm using the startup script in QjackCtl to run the commands I need. I have QjackCtl configured to startup automatically. It's starting up and running the commands OK; I see the programs come up when I boot the computer. But one thing is not working: a shell script named crossover_3chan, that invokes the ecasound application, which I'm using for a 3 channel speaker crossover network. This crossover_3chan script works fine when I run it manually, but for some reason, running it within the QjactCtl startup script is not working. When I execute ps -aux and look at the processes, it's not there, until I run it manually. Here is the QjactCtl startup script I'm using:

#!/bin/sh
sleep 2
/usr/bin/a2jmidid -e &
sleep 2
/usr/bin/aloop-daemon &
sleep 2
export LADSPA_PATH=/usr/local/lib/ladspa:/usr/lib/ladspa
sleep 2
hdspmixer &
sleep 2
"/home/gibbyj/Pianoteq/Pianoteq 5/i386/Pianoteq 5" &
sleep 4
crossover_3chan &

I've tried various ways of invoking the crossover_3chan shell script. Currently, I have put the script into /usr/local/bin, which is why there's no path in front of the name, above. But I also tried something like "/home/gibbyj/Downloads/crossover_3chan" & in the startup script, which didn't work either.

Would it help if I make this shell script an "application", giving it a name, like Pianoteq and the other applications? I've tried to figure out how to do that, in AVL/Debian, but am still not sure how.
Thanks very much for someone's help!
John
