Yes, I believe so. It's using [env~] to estimate the rms value, and
when changing the cutoff the rms level isn't constant across the
analysis frame. Also, [env~] gives the previous frame as a message,
which is then converted back to an audio signal. So there's some delay
in the adjustment. I could try and make one that doesn't use [env~]
and stays in the audio domain and see if that helps.

Hmm, I'm using the default startup libraries for Pd-extended 0.42.5 on
OSX. But it didn't occur to me that people may have disabled them. I
think the only non-default library I used is iem_tab, and I believe
they're [import]ed. Beyond that, mostly cyclone and zexy.

IIRC, because it internally formats the paths without considering that
they could start with C: or whatever. It might work, I just haven't

It's not practical for all of them. Some of them require mouse
interaction, some require calculating long tables which [until] is too
slow for (hence iem_tab), and others just do things that I don't know
how to do in vanilla. ;-) There are likely a few things here and there
that could be vanilla and aren't, but in general I stick with vanilla
if it's practical to do so.

Ah, thanks. I think that was from copying from the [biquadm.mmb~] helpfile. :-)
