How should I adjust the buffer size?

The latency (the time from which the DDJ-SX is operated until the sound is output) can be shortened by lowering the buffer size setting. If there are interruptions in the sound, increase the buffer size, but note that this makes the latency longer. Set the buffer size to the minimum value at which no interruptions in the sound occur.

For those using Mac OS:

The buffer size can be adjusted in the Serato DJ setup.

For those using Windows:

In the same way as at the buffer size setting in the Serato DJ setup, the buffer size can also be set by setting the kernel buffer number in the DDJ_SX ASIO settings utility.

Use the procedure below to set the buffer size to the minimum value at which no interruptions in the sound occur.

Check that no interruptions in the sound occur with the Serato DJ’s default setting (buffer size: 512 samples).

[If no interruptions in the sound occur with the default setting]

1. Set [USB BUFFER SIZE (LATENCY)] in the Serato DJ software to the minimum buffer size at which no interruptions in the sound occur.

2. Launch [DDJ_SX ASIO Settings Utility], change [Kernel Buffers] to [2], and check that no interruptions in the sound occur.

3. If no breaks in the sound occur, set [USB BUFFER SIZE (LATENCY)] in the Serato DJ software to the minimum buffer size at which no interruptions in the sound occur. If interruptions in the sound do occur, change [Kernel Buffers] in the [DDJ_SX ASIO Settings Utility] to [3].

[If interruptions in the sound occur with the default setting]

1. Launch [DDJ_SX ASIO Settings Utility] and change [Kernel Buffers] to [4].

2. Set [USB BUFFER SIZE (LATENCY)] in the Serato DJ software to the minimum buffer size at which no interrruptions in the sound occur.
