SLEW

Smooths a signal: a rise time and a fall time, separately. Three things at once — portamento on a pitch, a smoother on a stepped S&H, and a cheap attack/release envelope if you feed it a gate.

The SLEW card as vimsynth draws it: its title bar, 2 knobs, 3 inputs down the left edge and 1 outputs down the right
SLEW on an empty rack — 32×13 cells, knobs at their defaults. Press a in the app and pick SLEW to get this card.

inputs

Down the left edge of the card, top to bottom.

incv
The signal to smooth. A pitch CV here is portamento; a gate here is a cheap attack/release envelope.
rise cvcv
Modulates the rise time.
fall cvcv
Modulates the fall time.

outputs

Down the right edge, in the same order.

outcv
The smoothed signal.

knobs

Left to right across the face — the dials in the picture.

rise0 … 5 s= 0.05 s
Rise time. As portamento on a pitch this is the glide.
fall0 … 5 s= 0.2 s
Fall time. Making it slower than the rise is what turns a gate into an attack/release envelope.
