hi
that is what I do:
#!/bin/bash
if ps xa | grep -v grep | grep "jackd " >/dev/null ; then
if ! ps xa | grep -v grep | grep "qjackctl" >/dev/null ; then
pidjackd=`pidof jackd`
kill -TERM "$pidjackd"
sleep 1
qjackctl &>/dev/null &
sleep 1
fi
else
if ps xa | grep -v grep | grep "qjackctl" >/dev/null ; then
pidqjack=`pidof qjackctl`
kill -TERM "$pidqjack"
sleep 1
qjackctl &>/dev/null &
sleep 1
else
qjackctl &>/dev/null &
sleep 1
fi
fi
# this part check if jackd is start prop
cekz=0
cek=`pidof jackd`
while [ "$cek" = "" -a $cekz -lt 4 ]; do
if [ "$cek" = "" ]; then
cekz=`expr $cekz + 1`
sleep 2
cek=`pidof jackd`
fi
done
# this part start applications if jackd run
if [ "$1" != "" -a $cekz -lt 5 ]; then
while [ "$1" != "" ]; do
$1 &>/dev/null &
# sleep 5 # if apps start to fast uncoment this
shift
done
fi
with this script I start all my Audio/Midi apps. I have add it to the
menuentry`s like that: /path/to/script rosegarden qsynth vkeybd
or
/path/to/script ardour qjacktuner
