Hi !

You may need some time to get them working but for me they do.LPF and HPF individually work.rear and front can be used by two different process, I tried somethinglike :aplay -Dplug:mediumhigh test.wav & aplay -Dplug:bass test.wavand it worked

> > > A well known jackd-capable LADSPA host is 'ecasound'.I've played some time ago with ecasound and I was able to do what I waslooking for with the following things :
------ ~/.asoundrc --------------------------------pcm.mediumhigh { type route slave.pcm "surround40" slave.channels 4 ttable.0.0 1 ttable.1.1 1 }
pcm.high { type route slave.pcm "surround40" slave.channels 4 ttable.0.0 0 ttable.1.1 0 ttable.0.2 1 ttable.1.3 1 }
------ ~/bin/play.sh ------------------------------#!/bin/sh
ecasound -q -a:1 -i:"$1" -efh:100 -a:2 -i:"$1" -efl:100 -a:1-o:alsa,plug:mediumhigh -a:2 -o:alsa,plug:bass
---------------------------------------------------
This works but I can only use my system with ecasound...
> Seriously, file a bug about lack .asoundrc debugging.Ok.I'm not sure anyway this is completely related to ALSA, maybe it's onlylpf and hpf LADSPA plugins that showed some incompatibilities with otherALSA plugins.

Though it helped me to addthe copymediumhigh and copybass plug to accomodate lpf and hpf inputs.

> By the way, which order/type crossover do you want ?If lpf and hpf worked together, they should be ok.If possible I'd like 12 dB/octave because that's what the Gemini CX-1crossover has and it suits my needs.
