Hello!

This is just one more 4069 SVF, but with additional BP feedback, which makes it more "waspy".

Example with 561LN2, sorry for accent: https://www.youtube.com/watch?v=6Vt1AKOakLE

Filer sounds good and dirty !! What is the range of CV on the FET transistors?

Thanks for the reply. Going to save this schematic and this information. The CV can always be scaled in other applications. Would be good to get my hands on the 561LN2 to hear a difference. For now the 4069 will suffice.
