The latency (the time it takes to output the sound after DDJ-RZX is operated) will be shorter by reducing the buffer size. Increase the buffer size if the sound breaks up, however, the latency will be longer. Set the minimum buffer size in which the sound does not break up.

For Windows

Adjust the setting in the [ASIO] tab of the DDJ-RZ settings utility.

If using rekordbox, click [LAUNCH DRIVER PANEL] in USB BUFFERSIZE of [SETUP] > [AUDIO] to start the DDJ-RZ settings utility.

For Mac OS X

If using rekordbox, adjust USB BUFFERSIZE of [SETUP] > [AUDIO].
