It should always be possible to do things like this - (sine (mul 500
(sine 4)))

Yep. That keeps on annoying me too and I will fix it soon.

If you also need to restart jack it could well be that the whizzbang
compiz effects are killing jack - fluxa may well segfault if jack
disappears.

With scheme bricks - lots of work to be done on all this soon.
