Expressive E now have their Touché controller on display. Having actually seen it now I get it. Basically you can think of it as a super sensitive modulation and expression controller, and it is very sensitive. It feels right if that makes sense.
With four CV outputs for each axis, plus 7 and 14bit MIDI controller data options. In this demo from Arthur we can see what sort of expression it can add to a Dave Smith Instruments Pro 2.
Not shipping till later in the year, its going to be a while before you get your hand on one.
