[sdiy] Questions about VCO control voltage amplification/buffering circuitry

[Harry Bissell Jr]

I would try hooking it direct first. Usually a CV output can drive
  many inputs without trouble.
  
  In some cases, the CV may be in the wrong octave for your
  use, or may be slightly out of tune, or scale.  In that case I'd build
  an external buffer with a gain and offset trimmer... and maybe some
  octave switches as an option. Then you can avoid re-calibrating your VCOs
  to the external source... if it is not absolutly the same

  If  I want to have the external control voltage output from an analog  synthesizer control my homemade VCO's through their control voltage  inputs, should I construct a buffer amp circuit to boost the signal  level input from the external analog keyboard going into my VCO's CV  inputs ?
