VCO idea

[steve.ridley at bbc.co.uk]

I'm currently overhauling four Ken Gale "Wavemaker"
envelope generator modules, which do a similar sort
of thing - several voltage controlled slope stages
which can be looped to work as a sort of VCO.
The difficulty with using them as a VCO is that 
altering the settings of any of the slopes or 
end points will alter the tuning too, so shape
modulation and frequency modulation are tied
together. 
 
It should be possibel to lash up something 
similar with a VC slope module (Serge?) and a
two row sequencer.
