[linux-audio-user] timing in "performance loader"-script

[Atte André Jensen]

Hi

I've written a bunch of scripts to start synths, and connect them. But 
sometimes it get's screwed mostly because of timing issues. When 
counting on client numbers for connecting stuff which app comes up first 
is important... So:

1) Can I avoid the client numbers alltogether? This seems to require a 
way to rename ams, since all clients are calles AlsaModularSynth. Is 
that (starting ams with a specific clientname?) possible?

2) Alternately: is there a better way to handle timing? So app2 will not 
start before app1 is up and running?

Here's an example of the scripts:

#!/bin/bash
options='--sched -+rtaudio=jack -d -odac -M'
csound_path='.patches'
ams_path='.patches'
zyn_path='.patches'

key1=`usb_keyboards | head -n 1`
key2=`usb_keyboards | head -n 2 | tail -n 1`
key3=`usb_keyboards | head -n 3 | tail -n 1`

noisepad=$csound_path/filtered_noise_pad.csd
