Digital Recorder


Popular, Easy-To-Use Recorder Gets Big New Features

The BR-900CD is one of the world’s most popular, easy-to-use portable multi-track recorders. With Version 2, BOSS takes the best BR features and expands it with dozens of new COSM guitar-amp models, plus a super-cool new drum-editing software app and 500 minutes of recording time via 1GB Compact Flash.

The Best Gets Better

With the same reliable and ultra-friendly operation as BOSS’s highly popular BR-864, the BR-900CD takes three big steps forward by increasing the front-panel fader count from four to eight, and adding a built-in CD-RW drive and Pitch Correction to the feature set. The BR-900CD is compatible with CompactFlash cards up to 1GB capacity, which provides up to 500 minutes of record time (standard mode) in one shot. Even with all of these great new features, the unit’s footprint remains small for ease of travel.

Expanded Recording Time

No need to worry about track- record lengths. With a 1GB Compact Flash card onboard, the BR-900CD Version 2 provides up to 500 minutes of recording time.

New COSM Amps Onboard

It’s a dream collection for guitarists. Direct from BOSS’ top-of-the-line GT-Pro come 46 types of COSM® guitar-amp models. Simply plug in and explore an amazing treasure trove of tone without the cost and hassle of dealing with physical amplifiers.

New Ways to Groove

The original BR-900CD was equipped with a built-in drum machine.Version 2 has a virtual drummer onboard as well, but with an advantage: a downloadable graphical Rhythm Editor software forcreating rhythm pattern and arrangements visually via Mac or PC. It’s the best of both worlds.

USB Spoken

Connect the BR-900CD to the outside world with one convenient USB connection. Import and export audio files and song data quickly and easily. Need to add some drum loops or vocal samples to your song? Simply drag and drop your favorite WAV files from USB-equipped computer directly into the BR-900CD. Conversely, you can export audio that you’ve created internally on the BR-900CD to computers.
