M-Audio Midiman Radium 61-Key MIDI Controller with USB Cable - USB Untested

M-Audio / Midiman Radium 61 keyboard MIDI controller with 61 velocity-sensitive keys, pitch-bend and modulation wheels, eight programmable sliders and eight programmable rotary controls. TEST STATUS: The keyboard was previously used successfully through the 5-pin MIDI output with external power. This is a historical owner-confirmed test, not a fresh comprehensive test of every key and control. USB power and USB MIDI operation have not been tested. The individual response of all 61 keys, velocity sensitivity, wheels, sliders, knobs, buttons, display and sustain input has not been freshly verified. INCLUDED: • M-Audio / Midiman Radium 61 controller • USB-A to USB-B cable No external 9 V power adapter, sustain pedal or original packaging is included. For normal computer use the controller can be powered through USB; standalone 5-pin MIDI use requires a suitable 9 V DC 500 mA adapter, which is not included. Compatibility with current operating systems and software is the buyer's responsibility. The keyboard shows substantial cosmetic wear, including scuffs, scratches, dust around the keys and an I Love Berlin sticker. Please review all photos carefully.
