The design of the Xkey37 is very similar to the original model. The ultra-thin enclosure (check out the photo comparison with an iPad Air), machined from aluminum, houses thirty-seven full-sized keys. Compared to the Xkey25, the keys on the new model are noticeably quieter, and they just feel more robust in general. I’m note sure if the Xkey37’s delayed introduction citing production issues had anything to do with the action. If it did, CME figured it out because the keys on this thing are seriously solid.
The icons on the controller keys for Octave +/-, Modulation, Pitch Bend +/-. and Sustain have been replaced with text for easier recognition. The USB port for computer connectivity is still on the right hand side of the keyboard. On the left, there is now a Xport for the new Xcable, a breakout cable which adds MIDI Out along with 1/4″ jacks for a sustain pedal and expression pedal.
