Slim, lightweight, USB bus powered, and compatible with all computer-based music software, the microKEY-25 is a great way to create your production setup. The microKEY-25 features the velocity-sensitive Natural Touch mini-keyboard that was acclaimed on instruments such as the microKORG XL and the microARRANGER. The proportions of the black and white keys has been adjusted for optimal playability, easy chording, and rapid phrase work; careful attention has been paid to the touch and playing feel. The "waterfall-type" keyboard makes it easy to play glissandos. This keyboard will accurately convey the dynamics of your performance to your software. Octave Shift buttons are provided. Using the UP/DOWN buttons allows you to shift the octave the appropriate number of steps so that, when used in conjunction with the Key Transpose function, the full range of notes in the MIDI specification can be covered. The microKEY-25 model provides a sustain button that implements the damper function. The microKEY-25 model provides a joystick that can also control pitch bend and modulation, as well as an arpeggiator function, giving you full control in spite of this model's space-saving dimensions, and providing a wealth of performance expression. The standard USB MIDI driver provided by Windows/Mac OS X is supported, so there's no need to install a driver. Simply use a USB cable to connect the microKEY-25 to your computer, and it's ready for use.
