Also discrete stuff if memory serves. Not difficult, as there is no
need for voltage control of th eparameters, and as its an AD
envelope only.

Actually, I'm quite convinced that it was the other way round,
that they replaced the discrete stuff with chips, once the
SSM parts became available. (I don't know; I'm just guessing.
They might have feared patent conflicts with the moog filter, too.)
