Hello. I have a problem with the Multiband Equalizer Ladspa plugin. The command ecasound -a:1 -i:blub.wav -el:mbeq,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 -a:2 -i:blap.wav -a:1,2 -o alsa works just fine and as expected. However, on adding the mbeq to the second chain with ecasound -a:1 -i:blub.wav -el:mbeq,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 -a:2 -i:blap.wav -el:mbeq,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 -a:1,2 -o alsa the first chain is muted. The second chain sounds ok. It is the same with ardour. On activating the plugin on the second bus, the first is muted. Can you reproduce this behaviour? Is this a problem with my local setup or might this be some kind of bug? I use a quite recent Debian Unstable. Apt-cache says Package: swh-plugins Version: 0.4.7-1 Package: fftw3 Version: 3.0.1-10 Do you need further information? I would appreciate any help. I also wounder what you are using for equalizing. Thanks, Burkhard
