Ableton Forum

Even Bitwig has produced a beta with not only polyphonic aftertouch but full 3 dimensional expression for controllers such as linnstrument and haken continuum. This has been confirmed to me by Roger Linn himself.

Seriously, it's 2015. Haken continuum, soundplane, and linnstrument are the future of controllers and use multichannel midi control as integral parts to their functionality. I'm glad Ableton put a bandaid on the latency issue, now they NEED to work on getting poly aftertouch supported.
