Got a spare A-180 multiple and need a simple slew to round off jaggy gates and S&H signals? Then get out your soldering iron and follow this simple schematic from the Doepfer DIY page.
As you can hear, it's great for removing the clicks you get when feeding a VCA with abruptly changing signals:
(before and after)
Filters also benefit from 'softer' control. I built this as a companion to my Plan B M23 ASR, but you could also feed the quad slew with the outputs of a clock divider like the 4ms RCD and take these outputs directly to your VCA. A cheap and small alternative to tying-up four envelopes!
I used a 4k7 resistor and 1uF capacitor, but you could try other values for a more or less rounded result.
Thanks to fonitronik for the suggested values and help!
