Akai APC40 (original MK1) Ableton Performance Controller in excellent open-box condition. Powers on and fully functional — all buttons, faders, encoders, and LEDs tested and working. Comes complete with everything from the original box: unit, AC power adapter, quickstart guide, software CD (unsure if used), and Ableton Live Lite Akai Edition serial card, plus USB cable. Box and foam packaging included. This is the original APC40 — the controller that defined hands-on Ableton performance. 8 channel faders, 40-button clip launch grid, 16 encoders with LED rings, dedicated device and transport controls. Out-of-the-box integration with Ableton Live — no mapping needed. Also works as a general MIDI controller in other DAWs. Condition: Open box, no signs of heavy use. Surface is clean, no damage to chassis or faders. Sold as-is, no returns. Ships securely double-boxed. Questions welcome.
