RGB backlighting assists in identifying pad states during performance.

Recommendations

For reliable performance, ensure your DAW recognizes the device and keep firmware and software drivers up to date. Use a powered USB hub only if your laptop’s USB port cannot supply sufficient power. Map encoders and pads to commonly used parameters in your project template to speed up workflow.
