Well, that would include me. :-) This seems software-oriented to you, while
it looks like hardware to me. I don't think I could properly design anything
for it. (Otherwise, I would jump on the $200 evaluation kit deal.)

Well, yes, that is pretty cool. Also, these chips are starting to blur the
lines between software and hardware. To quote Anadigm:
    "... dynamically reconfigurable FPAAs, the first analog integrated
circuits for audio that can change their parameters in real time or even
undergo a complete state change-all so instantaneously as to be inaudible to
the most experienced ear."

Real-time changes to the circuitry? Interesting! (Is it useful? Sure! Change
filter modes on the fly, for example.)

I must defer to your superior knowledge, JH, because I don't understand the
distinction that you are making.

Is that a requirement? Isn't linear okay? You never seemed like an expo
bigot to me. :-)

Seriously, I think I'm too much of a lightweight (knowledge-wise) to
understand what you see as the problems with this chip, aside from the
switched-cap filters.
