NAMM: Korg introduced the Sound on Sound (SOS) recorder, a battery-powered digital audio recorder that allows an unlimited number of overdubs or alternate takes to be recorded.

Each track, take or overdub is recorded as an individual CD-quality 16-bit / 44.1 kHz WAV file, and saved directly to a microSD or microSDHC card.

BWF (Broadcast Wave Format) timing information is embedded in each track, meaning all tracks will automatically line up when imported into a computer-based DAW system for further editing, mixdown and final playback.

The SOS can record up to 200 songs in the traditional linear manner, or be set to loop a specific section. Memory consumption is roughly 100 recorded minutes per GB (gigabyte).

The Sound on Sound (SOS) recorder will be available in April 2010 for $400.
