hallo,

am am really enthusiastic about the possibilitys ecasound opens up for me.
i would like to use it for students to learn more about sound und
signalprocessing in context of open source systems.

one thing i am trying and not getting to work is if it would be possible to
control the plugin parameters by an external program. i found some demos
that woked with spiralsynth and uses a named pipe to send midi note on/off
commands to the synth via a small python programm. this is exactly what i
would like to do. with spiral synth you can change the midi devive to a
named pipe in the config file and this works fine.

mkfifo midipipe
./p1.py > midipipe&
./SpiralSynth

i tried this in the ecasound config file (midi-device = /tmp/midi.pipe) but
it does not work, i get no reaction on controler change date sent through
the pipe.

mkfifo ./midi.pipe

python sim_midi_ctl.py > /tmp/midi.pipe&
ecasound -i null -o /dev/dsp -el:sine_fcac,440,1 -km:1,100,800,1,0

many thanks,
alexander tuchacek
