  Not long after, Lippold Haken created a keyboard
that's continuous rather than discrete (think of a keyboard like the fingerboard of a
violin); a successor of that is still sold today. 
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.
