csound is much higher level, I guess once all the building blocks are
defined it would be more practical to build things in text only, but
making complex filters is hard work. You really dont want to build an FFT
that way either ;)

SAOL is still block based AFAIK. This allows you to do some really neat
tricks with feedback, knowing that the latency is only one sample.
In principle you can run any system with a block size of 1, but the
performance will really suck. Maybe SAOL would be ok, anyone tried it?

Yes, but its lisp :)
