Another good VCSF trick, if you have a frequency shifter, is to send one of the outputs (lo or hi pass, by preference) into a mixer, and the other into the Frequency Shifter. The output of the FS then goes into the mix with the 'other' output from the VCSF. By varying the slope as well as the cutoff, you get very nice control over the 'shape' of the shifted harmonics being added back in to the "other half" of the signal.
I've found this to be a very powerful sound shaping tool, with hours and hours of squelchy goodness to be had playing around with all the interactions and possibilities ;-)
cheers,
