Akai Professional LPK25

*Akai Professional LPK25**.
It is a compact, portable **MIDI keyboard controller** (specifically, a Laptop Performance Keyboard) used for music production. It features 25 velocity-sensitive keys, a built-in arpeggiator, and basic controls like octave up/down, sustain, and tap tempo.
Because it is a MIDI controller, it doesn't make sound on its own—it needs to be plugged into a computer, tablet, or phone via USB to control music software (like GarageBand, Ableton, or FL Studio).
