[chuck-users] Filters blowing up: any news?

If you do SinOsc s=> dac and the 100.0 => s.gain, are you then able to blow
a speaker on a Mac laptop even if it's main volume is turned down? That's
the curious thing to me, how the filter messes up so badly it makes my
MacBook's speaker scream even though the volume is almost down to zero.

I know I should just test this myself instead of ask (I'm tired and going to
bed - i'll try tomorrow), but the point I'm making is that this filter bug
is bad in a way that can cause harm, and even though it may just the
MacBook, some kind of limiter should be put in there, I think.
