M-Audio

M-Audio makes affordable keyboard controllers and music-production hardware. The SynthForSale listings are mainly Keystation and Oxygen MIDI keyboards, ranging from compact 32-key models to larger controllers with pads, knobs, faders and DAW-oriented control. These products normally generate no audio by themselves; they send MIDI to software, hardware synthesisers or a host device. Compare key count, velocity response, controls, USB/MIDI connectivity and bundled software rather than judging them like sound-generating keyboards. M-Audio is a practical route into hands-on computer and module control.
