MIDI Keyboard Controller 49-Key White The A-49’s keys have a rounded shape for better reaction to the player’s touch and more comfortable glissandi. Other enhancements have been made to reduce the already low mechanical noise and eliminate vertical shake. All of these features add up to a keyboard that even the most discerning pros will appreciate. Add color to your sound and excitement to your performance by waving your hands over the invisible D-BEAM. The A-49 can assign all its controllers automatically for fully utilizing an external SuperNATURAL sound module such as the INTEGRA-7. It’s also a great second keyboard for controlling synthesizers that have onboard SuperNATURAL sounds, such as the JUPITER-80 and JUPITER-50. Mobile Music The A-49 was born for mobile use. It’s strong yet amazingly lightweight (less than six pounds/2.5 kilograms), making it easy to lift and carry. And although it has a very streamlined design, the A-49 features a full-size, premium keyboard with 49 velocity-sensitive keys. For the ultimate in portable convenience, the A-49 is powered from your computer’s USB bus — no power cable or adapter is required. It draws a minimal amount of current, which is ideal for a USB bus-powered device.
