There's some info on building a ribbon controller in the Analogue heaven
archives
http://www.midiwall.com/aharchives/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...
