About Boss Micro BR

The Micro BR Digital Recorder, the world's smallest professional studio, is an innovative, high-quality, and versatile tool designed for musicians, DJs, and other audio professionals. This compact yet powerful device, slightly larger than an iPod, is the ultimate portable companion for recording and playback of audio content.

The Micro BR Digital Recorder offers four simultaneous playback tracks, supplemented by 32 V-Tracks, providing ample space for multiple takes and the selection of the best material for your final mixdown. This user-friendly device also supports MP3 compatibility, allowing you to load, play, and even slow down your favorite tracks without altering the pitch, making it an ideal tool for learning new songs or licks.

Equipped with a built-in multi-effects processor, the Micro BR Digital Recorder enhances your audio with quality effects. It also features a time-stretch algorithm, enabling you to change the tempo of your tracks without affecting the pitch, a valuable feature for audio editing and phrase training.

This durable device also includes nearly 300 drum patterns that can serve as a foundation for your songs or as a source of inspiration. These rhythms play back independently, not consuming any of your four playback tracks.

The Micro BR Digital Recorder also boasts a built-in microphone for quick capture, a tuner, USB connectivity, and an SD Card slot. All your data is stored on convenient SD media, making file transfer and storage a breeze. Despite its small size, measuring just 136.0 mm x 81.0 mm x 21.4 mm, this device packs a full studio's worth of features, making it an indispensable tool in any musician's gear bag.
