More Multi-Touch Keyboard Playing

As an addendum to yesterday’s teaser of the Evolution multi-touch keyboard, readers send along a couple of other examples. Andrew McPherson has a terrific example of an add-on, multi-touch, capacitive surface that can go on any keyboard (so, basically the same idea). Description: This video demonstrates a set of capacitive touch sensing piano key tops which mount on top of any existing piano or MIDI keyboard. The key tops sense up to three touches each by position and contact area, letting the performer continuously and polyphonically shape every note in multiple dimensions. The system connects to a computer by USB …

Expressive Soundplane Touch Instrument: Decibel Video, Preorder, Tour, Images

Touch on devices like the iPad is functional, but limited in its expression – there’s no pressure or tactile feedback. That’s why we’ve enthusiastically followed Randy Jones’ “continuous capacitive sensing” technology on the Soundplane for some time. Sensing pressure, it behaves more like an acoustic instrument might – that is, if such an acoustic instrument were possible beyond the imagination of the digital realm. As advertised, it “transmits x, y and pressure data for every key continuously at 12 bits of resolution and about 1000 samples per second, letting players move beyond the ADSR envelope model of synthesis and articulate …
