I am sure this has been covered on this list before--if it is not too much
of a trouble where can one get the new version of cyclone?

Also, there are some improvements on pd-l2ork side of things that I've
implemented that may detract from Max behavior but also offers other
benefits. For instance, coll object can be threaded and as such allows
loading of large files without dropping samples, albeit at the expense of
determinacy, so one in these cases must rely on outputting done loading
bang signal before working with the cool object. This option is fully
backwards compatible and the default behavior is non-threaded. It would be
great if we could have those merged so that we don't have to maintain two
separate versions of the cyclone library.

this has been corrected in the new cyclone library

actually, both cartopol~ and poltocar~ were "wrong" in the same way, but
for extended 0.42 only poltocar~ was corrected, this incomplete fix ended
up ruining spectral processing that was actually working before that.

get the new cyclone, many objects are being corrected
