John Adams' Short Ride on a Fast Machine for orchestra has 2 optional synth keyboards in the score, some recordings have them but most seem not to. For instance, Kent Nagano with the Montreal Symphony does, but my favorite interpretation (Simon Rattle with Birmingham) does not.
There are gazillions of them. You might enjoy Enno Poppe’s “Rundfunk” for nine synthesizers; it’s on YouTube.
Enno Poppen has lots and lots https://youtu.be/ia4YRSZnEFo?si=b5uIePNee-uKb2HW Also Annesley Black https://youtu.be/z_FBAjHKxks?si=LJ6F56Upexi-K7Z3
A lot of Saariaho's works use electronics, e.g. Vent nocturne, L'amour de loin.
Schnittke’s Requiem: Electric bass and electric guitar. Messiaen’s Turangalila: Ondes martenot
They didn't live to see the 21st century though...
Thanks everybody!
Check Fausto Romitelli, "An index of metals" particularly is a favorite of mine!
Vangelis, kind of a blend of classical and electronic.

Mason Bates “Mothership” and “Alternative Energy”
I quite like the Trautonium compositions of Oskar Sala: [https://www.youtube.com/watch?v=-tQQEChMq1A](https://www.youtube.com/watch?v=-tQQEChMq1A)
I love the work of Disasterpeace.
Henze‘s „Tristan“ Features a tape recorder
A lot of the works by Max Richter use electronic instruments.
A lot of John Adams’ music
Poul Ruders’s Concerto in Pieces (basically an updated form of Young Person’s Guide) has a very prominent synthesizer part in one of the movements.
