List of MPE Hardware Controllers (and More) – Page 3 – Roger Linn Design Forum

Maybe, I wouldnt like to guess either way. I’ll wait for the manual. Some in the industry do conflate MPE and poly aftertouch, but I cannot reach a conclusion either way at this stage.

In any case devices with normal keyboards that do support MPE usually dont bring any extra dimensions of expression to the mix, just support for transmitting the poly aftertouch MIDI data in MPE form rather than traditional form. When the Hydrasynth did this it at least had a synth engine with MPE support so its MPE mode did actually unlock something extra if the Hydrasynth was paired with a full MPE controller. With keyboard devices that are just controllers, the only advantage MPE mode looks like it will have is the ability to control any synths you have that might support MPE but dont support poly aftertouch MIDI messages.

By the way, the presence of the PolyTouch logo on the Korg images implies that Korg have licensed the poly aftertouch keybed from ASM.
