VC pulse width on VCO1 is pretty easy. Jack socket to the wiper of
the PW pot through a pot mounted as a variable resistor. I'm sure
there are better ways but it works for me.

More easy mods that I should have done but haven't : separate
outputs for each VCO (FM of VCO or VCF by VCO), separate outputs
and inputs for each filter (parallel, LPF into HPF), non-inverted
output for EG2 and/or a couple inverters to turn rising slopes
into falling slopes and vice-versa.
