Thank you for all your inputs, very helpful.
yes, i would have to combine a capacitive sensor 8or an alternative) with a pressure sensitive one, i guess.
i´ve been looking into the Coagula MIDI Ribbon Controller, but consider it as an extra project, which maybe can later be combined.
Also thanks for the patent link, it´s quite advanced as it seems, but great to get some info on the original functionality.
this can get me started, thnx!
