Equipped with a pro-quality 76-note keyboard and weighing less than 21 pounds (9.4 kg), the BK-9 is surprisingly light, making it easy to carry anywhere you want to play. Its user interface has been designed for maximum efficiency and ease of use while performing, with an innovative dual LCD system, logical panel layout, and many dedicated and user-assignable controls. 10 Favorite tones can be stored for each real-time part, an extremely convenient feature for live playing. 1000 onboard Music Assistants provide instant setups for every musical genre, and you can save an unlimited number of custom setups as Performance Lists to USB memory.
Massive Sound Selection
A flagship instrument deserves a flagship sound set, and the BK-9 delivers with over 1,700 fantastic sounds and 70 drum kits. 22 sounds feature Roland’s renowned SuperNATURAL technology, providing ultra-realistic acoustic instrument tones with an incredible range of natural expression. Also included are 500 all-new tones, specially selected for the BK-9 from the expansive Roland libraries. The Virtual Tone Wheel sound engine puts legendary organ tones at your fingers, with front-panel harmonic bars and a rotary effect for authentic organ performance. The BK-9 is also equipped for future expansion, with a User Tone area dedicated for upcoming BK-series sound collections.
Remastered Rhythms
Filled with full-ensemble accompaniments in almost every musical genre imaginable, the BK-9 lets you lead the world’s most versatile backing band as you play. 540 built-in rhythms include 25 new selections, and all the rhythms have been remastered with the BK-9’s superior sounds and powerful new effects processing for impressive audio quality straight from the recording studio. Via USB memory, unlimited additional rhythms can be added, and MP3, WAV, and SMF files can be played as well.
Multi-Effects and Onboard Mixing
Five independent multi-effects engines (MFX) offer an enormous range of sound processing possibilities, with three MFX dedicated to rhythms and two MFX dedicated to real-time parts. Global reverb and chorus effects are available as well, along with two mastering processors that allow you to optimize the sound of the rhythm and real-time sections separately to suit performance venues and add final polish for recordings. A great new feature for live playing is the Mixer function, which gives you instant adjustment of rhythm and real-time part levels, MFX parameters, and more using the harmonic bars on the front panel.
Powerful Tools for Creativity
A built-in 16-track sequencer provides a professional platform for composing and editing SMF data, while the Rhythm Composer lets you create and customize your own rhythms with ease. The convenient Chord Loop feature allows you to record and save chord sequences to drive the rhythms, great for generating on-the-fly backing patterns for two-handed solo/melody playing or preparing complete song arrangements for live performance, practice, or composition in the sequencer. With the Audio Key function, audio files stored on USB memory can be assigned to the top seven keyboard keys for quick-access playback while performing. Additionally, BK-9 performances can be easily recorded directly to USB memory as CD-ready WAV audio.
Extras for Entertaining
If you sing or work with a vocalist, you’ll appreciate the BK-9’s convenient XLR microphone input, which features phantom power, a dedicated reverb effect, and easily accessible front-panel controls. A composite Video Out jack is also provided, allowing you to display embedded MP3/SMF lyrics and chord symbols on an external video monitor for performance assistance or sing-along entertaining. Photo slideshows can be displayed as well, letting your audience enjoy custom images while listening to your music.
Roland Wireless Connect and Free iOS Apps
The BK-9 is compatible with Roland Wireless Connect, which provides cable-free communication with Apple’s iPhone, iPad, or iPod touch via Roland’s optional WNA1100-RL Wireless USB Adapter. An iPad can also be connected directly to the BK-9 with a USB cable using Apple’s iPad Camera Connection Kit. Many free iOS apps are available to enhance your BK-9 experience, including Air Recorder for jamming and capturing performances (iPhone/iPad), BK Partner for selecting tones and rhythms (iPad), Lyrics Viewer for displaying SMF lyrics (iPad), and a number of others.
