Freeware - Cherry Audio Surrealistic MG-1 VSTi Plugin

https://cherryaudio.com/products/surrealistic-mg-1-plus

The fun and funky Surrealistic MG-1 Plus Synthesizer is a super authentic recreation of the Realistic MG-1 synthesizer sold in Radio Shack stores in the 80's. The Surrealistic MG-1 Plus delivers fat analog tone in spades, along with a unique polyphonic oscillator section, "bell tone" ring modulation, glide, auto repeat note triggering, oscillator sync, and a number of improvements that tremendously expand its capabilities. Best of all, it's absolutely FREE!
