Could someone talk a little bit about the Post-Lawsuit filter (PLF)?
The description on the website is a bit lacking. For example:

1) How steep is the rolloff? I'm guessing it's 24db/octave.
2) What's the difference between the control inputs and the FM input?
3) Does the FM Amount knob only affects the FM input? If so, are the
control inputs fixed to 1V/Octave?
4) I've read that the ARP 4072 filter (which the STG filter is NOT
based on) only reaches 12 kHz. Does the PLF also has this limitation?

Finally, would it be possible for someone to upload some mp3, for
example, by running a sawtooth or square through the filter and
sweeping the cutoff at low, mid, and high resonance settings? I know
this is asking too much, but I'm really interested.

Thanks!
