   Now my question.
   The main reason why I want to build a tracking (i.e.
   V/Octave) delay is the use as sound source (Karplus /
   Strong - sp? - and "poor man's physical modelling" stuff.).
   The main reason why I have not yet built a tracking delay 
   is the analogue filter problem. 

Instead of bucket-brigade technology, how about a pure analog
exponential voltage controlled delay line?  If you implement a Hammond
Flying Chorus delay line with OTAs, it's entirely possible to do it
with two OTAs per LC stage.

How many stages would you need?
