Extremely reliable, maximum control.

This MIDI controller keyboard features 61 full-size velocity-sensitive keys, 8 of each assignable knobs and sliders, mod and pitch wheels, and a 3-digit segmented LED display with value-select slider. Basic settings are easily accessible and set through labeled keys across the top 2 octaves. It has a sustain pedal socket, of course, along with USB data (requires a legacy driver available to download from M-Audio, which works fine on Windows 10). The USB data port also receives power as an alternative power source if for some reason you can't use its own AC/DC adapter. The 'USB' MIDI-out DIN socket transmits signals received via USB, including MIDI extensions such as Yamaha XG control signals. I have owned this keyboard for many years - at least 15 years - as the controller for my Yamaha MU10, and it has never let me down. The keybed is still even and the unit has survived multiple moves (including international, without flight case) and massive dust build-up.
