Now, not to get too egg punk, but I assume hardware synths are fine to post here, but what about software synths? Specifically, Puremagnetik currently has a sale on 5 software instruments based on electronic strummed instruments like the old omnichord. $12 for the bundle, but be warned that only three are stand alone vsts, and the other two only work in Kontakt/Ableton/Logic.

From the link:
"Chordophonic Devices brings together five of Puremagnetik's innovative plucked and strummed instruments, each offering a unique take on electroacoustic expression. Whether it's physically modeled plucks, stochastic strumming, or vintage Omnichord textures, Chordophonic Devices unlocks a world of harmonic and percussive possibilities.
Use Omiharp to craft lush electronic strums, Voga to generate evolving plucked phrases, or let Arkinaut transport you to a world of resonant, ancient timbres. Dial in Ultrakord for retro-inspired Omnichord textures, or explore the minimalist charm of Harpitron’s Tronichord emulation. No matter which path you take, Chordophonic Devices offers an expressive plectrum trove for composers and sound designers alike."
