YOUR PERSONAL BACKUP BAND
Perfect for solo entertainers and home hobbyists alike, the BK-3 Backing Keyboard brings a new level of performance to entry-level auto-accompaniment instruments. Featuring a wide range of quality onboard sounds and rhythms, song playback via USB memory, built-in speakers, and more, this portable, self-contained keyboard puts the power of a full ensemble under your fingertips. From one-person shows to social gatherings to personal practice, the BK-3 brings endless hours enjoyment for playing all musical styles.
Wide Range of Sounds and Rhythms Onboard
The BK-3 is filled with sounds and rhythms covering an extensive range of music genres from around the world, including Eastern Europe, Latin America, and Asia. There are over 850 tones and 50 drum kits built in, providing a universe of voices for melody playing and accompaniment. Compatibility with GM2, GS, and XG Lite formats ensures high-quality playback with Standard MIDI Files.
Play Backing Tracks and Rhythms via USB Memory
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 easily 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.
Easy Audio Recording
A dedicated front-panel button makes it simple to record audio directly to USB memory, allowing you to capture full-ensemble BK-3 performances any time you wish for self-evaluation and sharing with friends and family. Your recordings are saved as CD-quality WAV data, making it easy to transfer them to your computer for burning audio CDs.
Roland Wireless Connect for iPhone and iPad
Compatibility with Roland Wireless Connect allows BK-3 players to communicate with an Apple iPhone or iPad over a wireless network via the optional WNA1100-RL Wireless USB Adapter. There are a number of fun, free iOS apps available, including Air Recorder for capturing BK-3 audio to your iPhone, and Lyrics Viewer for displaying SMF song lyrics on your iPad. And with Show Your Music, you can create video clips of your music performances and share them on your favorite social networks!
