Three main factors can cause this and there are three possible countermeasures.
■When buffer size is the cause
If the buffer size is too low, sound cutting or noise may occur.
You can adjust buffer size in Serato DJ Lite [Setup] < [Audio] < [USB Buffer size].
First, select a large value such as 20 ms. If the problem clears up, adjust to a value small enough that you can’t feel a delay (latency).
*The appropriate value depends on the system environment.■When the connection or other equipment is the cause
An unstable connection with your PC/Mac may cause these problems.
To solve this, shut down your PC/Mac and disconnect all other USB devices and USB hubs.
Then, connect the DDJ-FLX4 directly to a different USB port.■When your system (PC/Mac) is the cause
