For keyboardists on the go size and weight are key considerations. We applied our M80 Hybrid case design to create an incredibly light yet ridgid case for 49 and 61 key controllers. An innovative dual hinge design allows for either top-loading quick access or traditional horizontal opening. Create a custom fit for your keyboard using the internal width and depth spacers. Rugged construction with a water resistant Sharkskin™ outer shell stands up to abusive travel. Keep a low profile with the deep front accessory pocket. Go Play. These measurements represent the inner capacity of the M80-K61 case. If you are unsure about the fit for your keyboard make sure it does not exceed any of the maximum dimensions shown just to be safe. Fits most 49 and 61-key keyboard controllers including Nord Electro 3 61 M-Audio Axiom 61 Korg X50 61 Akai MPK61 and Roland JUNO-Di 61.
