Boss BR-864
A compact digital multitracker that traded the tape deck for a USB port and a pile of built-in Boss effects.
Overview
The BR-864 landed in Boss's BR line of digital multitrack recorders just as the home computer was rewriting the whole category. Boss had been developing the BR range for several years by then, retiring aging models now and then in favor of improved versions. The BR-864 was one of those replacements. The headline change, as Sound on Sound (July 2005, p.58) saw it, was the USB interface. It finally let a standalone multitracker talk to a laptop without a stack of adapters and workarounds.
The USB connection was a big deal. According to EQ (January 2004, p.44), the BR's USB mode exposes recorded material as files in a "USB" sub-folder. The user can drag them to a hard disk and treat them like any other audio file. The same article notes the reverse works too: audio can be imported back into the BR. For a project studio running a portable digital multitrack next to a computer, that round trip turns the recorder into a capture and editing front end instead of a closed island.
Sound on Sound (July 2005, p.58) also flagged the BR-864's "powerful effects processing." Effects have always been Boss's home turf. With them built into the recorder, guitar and vocal parts can be shaped on the way in rather than patched through outboard gear. The review called the unit a digital multitracker that "boasts powerful effects processing and built-in USB facilities."
The record does not give the fine print. The fact sheet for this model is effectively empty: no channel count, no recording resolution, no media type, no price, no production years. Treat any specific spec on a used BR-864 - track count, sampling rate, storage format - as unverified until it is confirmed against the unit's own documentation. What can be said with confidence is the basic shape of it: a Boss multitracker from the mid-2000s with onboard effects and USB file transfer, reviewed by the trade press of the day as a capable, effects-rich alternative to a computer-only rig.
Verify the specifics on the individual unit before buying. The published record here is thin.
