The MAT-02 data sheet at http://www.analog.com/pdf/mat02.pdf shows how to 
compensate for bulk resistance error in Figure 20 and the text describes how 
a single compensation point can be used for complex circuits. 

Seems to me this was a hot topic when I first found synth-DIY in '96.
Maybe it's time to start indexing the archives?
