free suzuki omnichord/QC-1 QChord alterative or plug in

hi! i've been looking everywhere for a free omnichord replica plug-in for logic, i know its weirdly specific and you could probably find "better" synths instead, but i'm looking for something as similar as possible to it, i'm super new to all of this and i don't know what to search to find them, i found some payed omnichord ones but i cant afford it.

if you know any free (i think they are called granular synthesizers) that sound as close to the omnichord as possible , pls let me know!
