I have built and tested a little portamento circuit.
It's nothing special, only that it has minimum part count,
and you can switch between  off / linear / expo with one
single on-off-on switch which alters the feedback path from
one opamp to two opamp stages.
If there is some interest, I might post or mail or upload
some hand-drawn GIF.
