This unit is required to use the Squier by Fender Stratocaster guitar and controller with Rock Band 3 on the Nintendo Wii.
Designed for use with Rock Band 3, the MIDI PRO-Adapter allows musicians to use their real MIDI keyboards, Squier by Fender Stratocaster Guitar & Controller or MIDI drum sets to play Rock Band 3.
Plugging directly into the console via USB, the MIDI PRO-Adapter works as an interface between the console and MIDI instrument, converting the MIDI messages into console controller data which the game translates into on screen action. The MIDI PRO-Adapter features a velocity sensitive adjustment for MIDI drums designed to reduce cross-talk during play. A full D-Pad and standard gaming controller buttons are located on the PRO-Adapter to deliver seamless console integration and navigation of the game menus.
