 re. qtractor: did you notice that audio effects are applied through
 track plugins, ladspa, dssi or native vst? in a nutshell track plugins
 perform the very same purpose of a stand alone jack-rack instance.
 anyway, this is not that a novel concept: ardour, rosegarden, muse,
 all do offer this rack-like plugin capabilities.
 
You mean in rosegarden and muse you can add also LADSPA effect plugins?
About dssi. I thought dssi where instrument plugins, but they can create
effects too?
