Operation is possible. When using DDJ-SX3, pay attention to the following points.

(1) DDJ-SX3 automatically switches to the "mode optimized to Serato DJ Pro" when Serato DJ Pro is running and to the "general purpose MIDI controller mode" when Serato DJ Pro is not running. Furthermore, the general purpose MIDI controller mode can be forcibly set in the utilities mode, regardless of whether or not Serato DJ Pro is running. For details, see "Forcefully using the unit as the general MIDI controller" of the operating instructions.

(2) In order to operate the MIDI-compatible DJ software with DDJ-SX3, the various operating interfaces of DDJ-SX3 must be assigned to the various functions of the DJ software.
For details on assigning the interfaces, see your DJ software's operating instructions.

Operation is not guaranteed when the PC/Mac has been restarted from the standby or sleep mode.

TRIM: Adjusts the level of the sound input to the respective channels from the deck of the DJ application or external device.

Examples of use
1. Play tracks.
2. Move the channel fader away from you.
3. Adjust TRIM so that the orange indicator on the channel level indicator lights at the peak level.
4. Use MASTER LEVER to adjust the sound level of the speaker connected to the MASTER OUT terminal.

It depends on when you purchased the tracks. If you purchased the tracks before February 22, 2012, they cannot be played because DRM is applied. If you purchased the tracks on or after February 22, 2012, they can be played because DRM is not applied.

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 Mac users
The buffer size can be adjusted in SETUP of Serato DJ Pro.

Click the Audio tab in SETUP of Serato DJ Pro and then click the [LAUNCH DRIVER PANEL] button to display the ASIO settings utility screen. On this screen, you can set the buffer size and kernel buffer size.

1. Start [DDJ_SX3 ASIO Settings Utility] and set the buffer size to the minimum value at which no interruptions in the sound occur.
2. Then change the value to [2] in [Kernel Buffer Size] and check that no interruptions in the sound occur.
3. If no interruptions in the sound occur, set the buffer size to the minimum value at which no interruptions in the sound occur. If interruptions in the sound occur, change the value to [3] in [Kernel Buffer Size].
