For the record, formant~ was now also added, so I have formlet~, formant~, vosim~ and paf~ (all with multichannel support) already inclued into ELSE, and I'm gonna stop here for the time being...

F12.paf.control.pd says that there is a paf~ external, but I can't find it. This page by Miller Puckette describes paf:

just use his patch, no need to look for an external,

the max external for example does not support signal input, therefore a custom patch is there also preferred.

why?

only reason I can think is if you wanna do FM, which is unlikely. In the code we have signal ramps by the way and it's more efficient
