Patch of the Day - The FM Ratio Stepper

Who says you can't do decent Linear FM in the analogue domain?

The FM Ratio Stepper

Today's patch was inspired by my GAS for a Modcan VCDO and William H's excellent FM tutorial.

The idea was cribbed from the lovely 'harmonics' VCDO demo, with William H's ratio to pitch conversion PDF proving invaluable.

I used two channels on my Kenton Pro 2000 II to provide the separate CV's which were fed to my Livewire AFG (carrier) and Cwejman MMF-1 (modulator).
