We did a podcast special with Roger Linn last year, where we talked in depth about his new playing surface. Designed around the guitar fretboard paradigm, it offers multi-dimensional touch control, with velocity, pressure and slide, per "string".
Allowing for some very expressive playing, its possible to do things with the Linnstrument, that you just cannot do elsewhere easily.
Also on the team is Eigenharp officianado Geret Bevin, whos working on the code behind this new controller.
The Linnstrument is availabe for order now at RogerLinnDesign.com at $1499
