Another way to do stereo from mono is with a multi-mode filter. Plug the High Pass into one channel and the Low Pass into the other. Use a LFO to move it around. For fun 2 different multi-modes can be used and the LP and HP channels reversed. The Phasing will do some wild stuff if the source is the same for both. Also if the multi-mode has separate band pass and notch, those can be patched left and right for neat effects to. Don't forget to play with the resonance.
