Hi All.  I banged together a little web app to play around with filter 
pole mixing, of the Oberheim Xpander type.  You can mix poles in varying 
amounts and see the output magnitude shape as well as the transfer 
function.  Y axis is Db and X axis is log scale based on normalized 
frequency (so basically 1 equals the cutoff frequency).  Haven't done 
phase plot yet.

If you have an interest in this sort of thing check it out:
