Check the following.

2. Are the sound volume adjustment control and slider set appropriately?
Check “Playing tracks and outputting the sound” in Operating Instructions of this unit. Operating Instructions can be obtained from the support page.

3. Is the buffer size adjusted appropriately?
The latency (the period from when this unit 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.

The buffer size can be adjusted in [Preferences] of rekordbox.

4. Is the master tempo function on?
When the master tempo function is on, the sound quality changes because key control processing is performed to keep the key constant. This change in sound quality is in accordance with the specifications of the product and is not a malfunction.

5. Are you using a USB hub?
⇒ A USB hub cannot be used. Be sure to connect this unit directly to a USB port on the computer.

6. Are other applications running?
Exit all other applications including the screen saver and resident software.
(Disable the internet connection to ensure the security of your computer before exiting antivirus and other security software.)
