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!
