Equipped with 25 velocity-sensing keys and an advanced design for reliable recording. By combining the great-feeling touch that Korg has developed for its professional MIDI keyboards and the low-profile thinness of recent computer keyboard innovations, the nanoKEY2 provides a superior keyboard response for its class and size. The touch and velocity response have been carefully tuned, ensuring that your expressive performance will be conveyed accurately to your software. The Octave Shift buttons borrowed from Korg\’s MIDI controllers allow the overall pitch to be shifted four levels, either UP or DOWN, in octave increments. For enhanced performances, the nanoKEY2 also provides Pitch Bend buttons, a Modulation button, and a Sustain button one that\’s indispensible for piano or electric piano performance. For each of these buttons, the on/off switching speed can be specified over four levels (using the Korg Kontrol Editor). The nanoKEY2 works with the \”Korg Kontrol Editor\” software available free on the Korg website. Load it into your computer, and use it to make detailed customized settings. Choose from a total of four velocity settings: three velocity curves or fixed velocity; specify the control change messages transmitted by the modulation button and the sustain button.
