It doesn’t have MPE nor does it have polyphonic aftertouch, only channel.
I came away from MoogFest determined to explore alternative controllers. I have my sight on the Linnstrument and on the Madrona Labs SoundPlane and everyone should check out the Marimba Lumina, one of the last things designed by Don Buchla with Joel Davel. It’s a giant MIDI controller in marimba configuration with extra pads and strips above the marimba keys for performance control. It has an 80 character display and an onboard synthesizer in addition to being a complete MIDI controller. Each of the four mallets is individually recognized and the board is splitable.
So were DSI to do something in the MPE space, I’d be very interested as well. And if they’re really considering a 76 note version of the Prophet X, I also hope they’ll consider adding a Voyager XL style touch strip above the main keyboard. That should be relatively simple to do and cheap enough. I love the two new touch strips. More touch controls, please.
