You can think of it as sort of a voltage-controlled panpot, but instead of 
panning between just two signals (left and right), it can continuously pan 
between eight different input signals, and send the blend to one output.  It 
pans from input #1 to input #2, then from input #2 to input #3, and so on 
down the line.  These signals could be audio waveforms, LFO waveshapes, or, 
more likely, outputs of different filters (Highpass, Lowpass, Bandpass, 
Notch, Moog, ARP, Radio Shack, Volkswagen, etc.).  This sort of thing can be 
much more musical than simple mechanical switching between the different 
sources, and obviously much more flexible than a 2-input panpot.  Juergen has 
designed two versions of this circuit - one specifically designed for 
scanning multiple filter outputs in his polysynth, and another 
general-purpose version that could be used for scanning between pretty much 
any group of signals.

I haven't looked at the schematics lately, so I don't remember if the circuit 
is DC-coupled (for scanning LFO outputs).  Is it, Juergen?  If not, could it 
be?
