i might be missing something that's pretty obvious...but is there support in Pd for complex numbers? or is there an external library for complex number arithmetic? thanks.

there most definately is support for them. i know some of the fm synths in the documentation examples use them.

the fft~ stuffz uses it a lot, you have many objects as pol2cart~, cart2pol~ it may be in the iemlib'z...
