Subject: ribbon control & construction ?

From: hodad1@...
Date: 1999-12-03

There's some info on building a ribbon controller in the Analogue heaven
I cant remember the details--it's been a year or two.
My 1/50th of a dollar: the strip that goes over the heat element on a bag
sealer feels very
much like the top strip on the Micromoog's ribbon controller--might be a
good substitute in a diy project.

Just wondering: has anyone ever built pressure sensitive controllers?
Seems like it would be easy if someone would tell me exactly how to do it...
