Native Instruments Komplete Kontrol A49 USB/MIDI Keyboard

If you're looking for a more affordable version of Native Instruments' S series USB/MIDI keyboards, the A Series could be just what you're after. The Komplete Kontrol A49 is essentially a cheaper version of the S49. Thankfully, it still has the NKS plugin integration, making it perfect for controlling things like virtual instruments and effects. The keyboard's on-board controls make it easy to use, while the semi-weighted keys make it a pleasure to play.
