This unit’s track information may not be in a language supported by the connected DJ software. Check the range of languages supported by the DJ software in that DJ software’s operating instructions.

Files in MP3 and ACC format support ID3 tags in which track information is embedded, so the artist name, album name, etc., can be read out from the file and displayed. Files in WAV and AIFF format, however, do not support ID3 tags, so the artist name, album name, etc., cannot be read out from them. To display their track information, the track information must first be edited at the “Edit” item. Note that with the Import from iTunes function, the file information in the iTunes library is consulted, so the track information is displayed even for files in WAV and AIFF format.

When thekey lock mode is turned on, key control processing is performed to keep the key constant, so the sound quality changes. This change in sound quality is normal considering the product’s specifications; it is not a malfunction.

To OS X Mavericks v10.9.x users:
It was recently discovered that some users may experience problems with some Pioneer DJ software and drivers under certain conditions.
- When a user's Mac pre-installed with OS X 10.9.2 has never been connected to DDJ-SB via a USB.

Pioneer DJ is currently investigating this issue to detect the root cause, but there is a valid work around.
Please see the effective workaround from this link.

Check the following:

1. Is the driver software installed? (Windows)
With Windows, the ASIO driver software must be installed.
(There is no need to install driver software with Mac OS.)
For instructions on installing the driver software, see the operating instructions.

2. Is the DDJ-SB recognized on your computer?
Windows: Check using the [DDJ Version Display Utility].
From the Windows [Start] menu, click [All Programs] > [Pioneer] > [DDJ_SB] > [DDJ_SB Version Display Utility].
The driver software’s version and the DDJ-SB’s firmware version are displayed.

Mac OS: Check using the Mac OS [System Profiler].
