Keyboard CV

[jteir at cc.hut.fi]

Hi! I don't know if this is the correct place to send questions, there is
probably a FAQ for this, somewhere, but anyway:
  I'm building an analog synth from scratch, but I have som questions
about the implementation of the keyboard. The oscillator is controlled by
a logarithemtric potentiometer at the moment, and this is a feature I
would like to maintain, even when I have a keyboard attatched, so that I
could drop or rise the pitch drastically whenever I want to. But there is
a problem: Since the oscillator is logarithmic controlled, a linear
resistance ladder for the keyboard doesn't sound right. But if I make a
logarithmetric ladder the keys will only have the correct pitch ratio
(semitone) at one particular position on the pot. That is, if i turn the
pot, the pitch will rise/drop, but an octave on the keyboard is no longer
an octave in pitch. 
  Is there a simple way to solve this?
