The Polysix and PS series ensemble circuits are related, but not identical.
Quite different in features, relatively similar in circuit design style.
I think the stock PS chorus was only switchable on / off. But in the schemos
I got from Korg Germany there is a hand drawn modification that puts a
variable voltage to the supply pins of the CMOS LFO chips (similar
to the way the Polysix does it) for Rate control.
