Akai MPK Mini Play Mini Keyboard with Built-in Speakers and USB Pad Controller The ultra-portable MPK Mini Play is based on the world’s most popular midi controller—Akai Professional’s MPK Mini—but now it comes packed with 128 sounds and its own built-in speaker. With 8 backlit MPC drum pads and a 4-way joystick for simple control, players have all they need to play their music anytime, anywhere. Four knobs (two banks capable of controlling eight different parameters) can be used to tweak sounds and edit multiple parameters in real-time, giving musicians even more performance possibilities. Powered by 3 “AA” batteries, the MPK Mini Play is built for hours of wireless fun.
