KeyLab 49 is a professional-grade 49-key USB MIDI Controller. It's entirely preassigned to work with the Analog Lab software, so it's ready out of the box to give you immediate and in-depth control over your sound. But KeyLab 49 is also a Universal MIDI controller, so it's compatible with any third party-software and hardware. Remapping the controls is simple with the included MIDI Control Center software.
