[LAU] Linux mixer

Hi, regarding to some mixer issues with Qtractor, discussed at other lists, I searched the Internet for a sane virtual mixer, but didn't find one for Linux. I need stereo or mono channels, it doesn't matter when stereo channels only provide balance, it's ok, real panning would be better. An insert (audio out/in) isn't needed, I could add an "insert" before I connect to the mixer. Inserting LV2 and LADSPA effects would be useful, but aren't too important, with one exception, each channel needs an EQ (Fons' parametric EQ or a similar EQ) and I need at least one _post_ fader aux send to a sub group or at least to an aux return pot for the stereo master sum. Pre fader aux would be completely useless. A mute and/or solo switch would be useful too, not needed, but it's important, that the mixer settings can be stored and restored. Regards, Ralf
