Independent shopping perspective
Roland’s black A-49 is a slim, lightweight MIDI keyboard controller with 49 full-size velocity-sensitive keys. Its rounded keys are designed for responsive playing and more comfortable glissandi, with reduced mechanical noise and less vertical shake. USB bus power removes the need for a separate power cable or adapter when connected to a computer. D-BEAM, two knobs, two switches, octave buttons, transpose control, and LED feedback keep hands-on adjustment close to the keys.
