Yes. (and, btw, hi Andreas!) You will need the zexy library. Get it here: ftp://iem.kug.ac.at/pd/Externals/ZEXY/
You should also checkout the downloads section at www.pure-data.org

hm, I could not create a z~ object in pd. The help system did not help either. Are You referring to an external or library?
