The black BK-3 Backing Keyboard from Roland is a portable, self-contained keyboard with built-in sound system. It includes music genres from around the world, including Eastern Europe, Latin America, and Asia. There are over 850 tones and 50 drum kits built in. The BK-3 is compatible with the GM2, GS, and XG Lite formats to ensure playback with Standard MIDI Files.

A dedicated front-panel button allows you to record audio directly to USB memory. Your recordings are saved as CD-quality WAV data, making it easy to transfer them to your computer for burning audio CDs. The BK-3 can play a variety of external backing formats from optional USB memory, including WAV and MP3 audio, SMF, and Roland rhythms (BK, E, G, and VA series). Playback tempo and song key can be adjusted to suit your vocal range or performing needs, even with audio files. In addition, a Center Cancel function reduces the volume of vocals in commercial WAV/MP3 songs, ideal for karaoke singing and minus-one playing.

This backing keyboard is compatible with Roland Wireless Connect which allows you and other players to communicate with an Apple iPhone or iPad over a wireless network via the optional WNA1100-RL Wireless USB Adapter (sold separately). Free iOS apps such as Air Recorder for capturing BK-3 audio to your iPhone, and Lyrics Viewer for displaying SMF song lyrics on your iPad are available. The Show Your Music app lets you create video clips of your music performances and share them on social networks.
