This is a Moog-inspired Voltage Controlled High-Pass Ladder Filter clone, based on the High Pass Filter by EFM (Electronics For Music).
The final circuit is also directly inspired by the comments and suggestions from Kristian Blåsol in his video Moog Highpass Transistor Ladder Filter – DIY Modular in a Week 7.5.

Im just about to build you ladder filter, but im wandering why it says CCW next to the pots ??
Martin – Denmark
CCW means “Counter ClockWise”
Let me know how it works 🙂
I assumed it was counter clockwise, but just dont see why 🙂
The CCW mark simply helps me orient the potentiometer in KiCad schematics editor 🙂
Ahh.. makes sense 🙂
Thanks for your answers.
