I use long linear ribbon softpots to build Open Sound Control controllers for my experimental instrument. (https://m.youtube.com/watch?v=nKFK_OhQv3k https://m.youtube.com/watch?v=nKFK_OhQv3k) I feel that the very subtle control I get on these softpots would work well for expression control. It wouldn't be difficult to hook one up to a TRS and make a very good expression controller. The only thing missing may be the ability to stay a particular position, as depending on how you wire it, it would go to full on or off when you release your finger. I get around this in my OSC controllers because I do software based latching in my microcontroller code. Anyhoo, just passing that suggestion along to anyone fiddling around with DIY expression controllers.
