Reminds a bit of the Chorus patch on the Korg M1.

A choir preset made with the Polysynth and a couple of stock fx. Reminds of the classic chorus patch on the Korg M1.

Version 2 of my formant synthesis patch. Cleaned up some stuff and added a 'darken' knob, which will shift down the overall characteristics of the formant (somewhat like a formant shift but also a bit sounding like an eq).
