The CMOs inverter 4040 as an analog element, there is a very famous synthesizer built around that. The EDP wasp, this one is from england around the 80s. Back than i think the designer used 4040 because they were available and cheap.

For those interested there is also a jasper clone out there a diy kit, since back in the the 80 all music as well as other companies simply have been open source by design (all schematics available for servicability) people nowadays can simply clone the old product 1:1
I think you meant the 4069UB inverter – 4040 is a counter.
By the way, I would love to see an EEVBlog video about circuits based on unbuffered CMOS gates.
There are some clever ways to use them, like https://www.edn.com/cmos-hex-inverter-generates-low-distortion-sine-waves/ and https://www.edn.com/single-hex-inverter-ic-makes-four-test-gadgets/
They are also a good match for crystal oscillators: https://www.onsemi.com/pub/Collateral/AND8141-D.PDF
My parents designed there house in Microsoft Excel 2003.
