Adjustable Infinite Slope Crossover

[Rarkov]

Hi,
After finally getting my circuit simulating correctly (PSpice Error Thread) I was wondering if it is possible to accuratley change the crossover point of an infinite slope xover using only a variable resistor? The aim (eventually) is to have a digitally controlled Infinite Slope Crossover for use in my Preamp.

I have included an updated (from the last thread) schematic and project file for Orcad 9.1 (and others I'd expect)...

Thanks
Gaz

Hi,
I see a few people have downloaded this - has anyone come up with any solutions yet? I tried a parametric sweep - but couldn't get it working.
