The Roland ED PC-300 is recognized as the world's first USB MIDI keyboard controller, released in the early 2000s (circa 2003). It features 49 full-size, touch-sensitive keys and offers plug-and-play USB connectivity, making it one of the pioneering devices for computer-based music production.

  1. USB & MIDI Connectivity: Connects directly to Mac or PC via USB for bus-powered, driver-free operation (on supported systems). Also includes a standard MIDI OUT port and sustain pedal input (compatible with Roland DP-6 or DP-2 pedals).
  2. Controls: Equipped with pitch bend and modulation levers, octave shift buttons (±2 octaves), and an assignable data slider for real-time control over volume, reverb, pan, or other MIDI parameters.
