Xpantastic!

Hi all,

Anyone have any suggestions how to obtain linear tracking of one oscillator to maintain a steady beating frequency across all octaves? 

I.e., some way to add a set voltage to osc1  pitch so that it stays X Hz above oscillator 2 regardless of pitch? Was introduced to this idea by new synths such as the subphatty, and also through the "ultrasaw" concept on the Aurturia minibrute. 

I tried this with the tracking generator by scaling the pitch frequency across the keyboard, but it only kind of worked (and not consistently). Maybe I should have tried using the same value across the tracking generator? 

It seems like it should be possible using some parameter, or combination thereof.
