I've owned a two-octave CME Xkey controller keyboard for a couple of years now. It's small and light enough that there's always room for it in my laptop bag, and since my gig includes playing through charts for Keyboard magazine's music lessons and technical how-to articles, it never leaves my side. However, I've certainly found myself wanting for a bit more room to spread out if I need to practice for a gig. Enter the new Xkey 37, which is decidely more keyboard player's keyboard than note-entry appliance.
Like the original two-octave Xkey, it has chiclet keys that are suprisingly more playable than they look, polyphonic aftertouch (no, that's not a typo), and buttons for sustain, modulation, and pitch-bend up and down. A notable new addition is the "Xcable," a breakout cable which combines sustain and expression pedal inputs and five-pin MIDI out so the player can control older sound modules and even MIDI-equipped analog synths. (Nope, there's no CV/gate yet, but I'm not sure how CME would fit the necessary analog circuitry into the Xkey 37's "wah-ferr thin" chassis.)
Look for a full review in the pages of Keyboard's June 2015 issue. Heck, we'd even welcome an Xkey 49 or 61.
