Adjusting the buffer size
This unit functions as an audio device conforming to the ASIO
standards.

software, etc.) is running, quit that application before adjusting the
buffer size.
Click the Windows [Start] menu>[All Programs]>[Pioneer
]>[DDJ]>[Pioneer DDJ ASIO Settings Utility].
! If the buffer size is made large, drops in audio data (breaks in the
sound) occur less easily, but the time lag due to the delay in the
transfer of the audio data (latency) increases.
! If the kernel buffer number is made large, breaks in the sound occur
less easily, but the time lag due to latency increases.
! Operate referring to the procedure below to adjust the buffer size and
kernel buffer.
If there are no interruptions in the sound with the
default settings
1 Gradually decrease the buffer size, setting it to the minimum
value at which there are no interruptions in the sound.
2 Set the kernel buffer size to [2] and check whether there are inter-
ruptions in the sound.
— If there are interruptions in the sound, set the kernel buffer size to [3].
If there are interruptions in the sound with the default
settings
