It doesn't do effects routing, which can be an advantage if you don't want to deal with that complexity. ecasound is kind of a middle ground with greater flexibility and greater complexity, then you have things like nyquist, clm, and csound, which are meant to be command-line invokable for non-realtime audio processing, but are full fledged programming languages rather than command line tools (ie. not only can you apply effects, but write them from scratch if so desired, and the effects have a much larger number of parameters, etc. (by the way, thanks gmail folks for making the "reply" button doing the right thing with this mailing list)
