The compact nanoKEY2 MIDI controller keyboard by Korg — no, not that one — is ideal for musicians on the go. This ultra-slim USB controller sports 25 velocity-sensitive keys with impressive responsiveness for a device at this price point. The octave up/down buttons offer access to the full range of musical notes, while the modulation, sustain, and pitch bend buttons grant a high level of expressiveness.

At $50, the nanoKEY2 is an affordable and easy-to-setup portable music production system. It comes in your choice of black or white.
