Only lowly Op-amp circuits, but it works ... I have even made my first

Hello Richard,

That looks great!  Thanks for sharing it with us.  I can't wait to try this 
with my own EWI controller, although I don't really have time for it.  Are you 
really able to get an accurate 1v/octave output with just those two simple 
trimmers and a summing amp?  I thought it would be more complicated than that.  I 
think you should add a portamento circuit, though.

Best regards,
Michael Bacich
