You think of a VCA that lowers/rises the Waveform level in proportion to
the note that is played? All you need is a VCA that is controlled by the
keyboard voltage.

This is more elaborate and costly you might think, since you need high
precisision components. We talked in synth-diy maillist about this some
time ago.

Hé Florian,

Dunno, this is how moog put in in words in their manuel for the 921 VCO: Both fixed and variable levels can be obtained from the front panel output jacks. It sounds exciting, but who does this a effect the waveform output? Does this not mean the frequency of the waveform can be changed?, but only the volume? 

I saw that you are the guy who wrote a book on modular synthesis. I studying the book by Allen Strange. But that's a though read!! (Although it's written in understainable english. 

Roel.
