Analog computing has been used by musicians for awhile now.

Synthesizers are basically analog computers. Bob Moog was an engineer whose genius was figuring out how to connect keyboards to lab equipment and how to hide enough of the guts to make the gear approachable to musicians. West Coast synthesists like Buchla took the opposite approach of appreciating the sound of analog computing for what it is.

Synthesizers tried to hide it for awhile behind layers of user interface, but especially with the Eurorack boom of the last decade or so you can really see that synthesizers are simply specialized analog computers. Lots of synth modules openly use the same terminology as analog computing: filters, amplifiers, multipliers, low-pass gate, sample and hold, sequencer, etc. Musicians like Hainbach use actual test equipment in their music.

Guitar effect rigs are also basically analog computers. They're just not used for numerical computation.

update: The Signal State is a Zach-like game where you solve puzzles by programming analog computers; in was inspired by Eurorack synthesizers.

No, synthesizers and guitar pedals are as much computers as a trumpet. "It translates the lip movement through the horn and amplifies the sound, thusly it's multiplying and therefore a computer!"

That is stretching the definition of a computer to absurdity, sorry.
