OOO Ooooh, if you happen to have a schematic for that passive decay envelope, I'd love to have a peek at it! (and of course save a copy)

Never tooe many envelopes...

While the key is held, the output of the AD is low, so the rate of the slewlimiter is low as well. On retriggering CV is added to the slew rate, et presto.
