rubber buttons tend to be dust magnets… 
I’ve thought about this from time to time too. My position: I think it adds to the OTB experience. It sort of reinforces the idea that I’m away from the computer and I like that.
Just for the craziness of it, I’d like to see a capacitive touch plate mod of the an Elektron box. Like the new Makenoise Rene sequencer but with a digitone brain.
I really like the tactile feeling, and the sound it makes. But yes, it is disturbing for people around that is not involved in the music making.
@NoiseLab I guess the Elektron machine(s) and the monitors are on the same desk/furniture? Maybe some foam pads under the monitors will absorb the resonance transmission a bit better? I guess it also depends on the placement of the monitors/subwoofer abd/or the machine(s), maybe some placing trial and error can fix the problem.
@Elektron please please please keep the switches/keys…please never ever replace them by rubber buttons/keys 
and they feel bad
