This thing here https://en.wikipedia.org/wiki/Continuum_Fingerboard ? Seems a bit like a digital successor to, or at least inspired by, the analogue 1930s "Trautonium" device (https://en.wikipedia.org/wiki/Trautonium) developed by Trautwein and Sala in Berlin, which used a length of resistance wire suspended over a metal rail. Both position (pitch) and pressure (volume)sensitive according to the description. Arno, DO4NAK
