This guide aims to assist users in resolving common issues encountered when using SoundSwitch in conjunction with Serato Performance Mode. Before proceeding with this guide, make sure you have already added your fixtures in Edit Mode, and that they work correctly during scripted track playback or autoloops in Edit Mode. Additionally, ensure your SoundSwitch is set to the "Serato" Input type in the SoundSwitch Preferences.

Issue 1: Unable to Establish Connection Between SoundSwitch and Serato


1. Open the SoundSwitch Software.

   - This step is essential to initiate the connection between SoundSwitch and Serato.

2. Navigate to Serato Preferences > Expansion Packs > Serato Remotes.

3. Activate the SoundSwitch remote if it is not already listed as an Active Remote.


If SoundSwitch is not available as a Serato Remote, follow these steps:

For Windows:

1. Confirm that the SoundSwitch Software is open.

2. Allow SoundSwitch through the Windows Firewall for both Private and Public Networks.

3. Check that the Bonjour Service is running:

   - Open the "Services" application on Windows and ensure Bonjour Service is present and running. If not, download and install it (may require a restart). Download here.

4. Verify that no Third-Party Anti-Virus tools (e.g., Avast or AVG) are blocking the connection. Temporarily disable or enable silent mode if needed.

After making changes, restart both SoundSwitch and Serato for the adjustments to take effect. A successful connection is indicated by the Blue LED Status indicator in the SoundSwitch Software.

Issue 2: Fixtures Responding to Only One Deck/Fader


1. In SoundSwitch Preferences, go to Performance Mode and confirm the following settings:

   - Fader Settings: Choose your desired Fader settings. Commonly, select "Upfader Only" if you don't use the CrossFader for mixing audio.

   - Ensure that the "External Mixer" option is not enabled when using "Deck 1-2" Mode.


If fixtures still respond to only one deck, it may be related to the Serato Crossfader and Upfader settings. Follow these steps:

1. Open Serato and select Serato Video (enable via Serato Expansion packs if unavailable).

2. Confirm that both the X-F Crossfader Link and both Upfader Links are active.

After confirming these settings, your fixtures should respond to both Deck 1/Upfader 1 and Deck 2/Upfader 2.

Issue 3: Fixtures Only Responding to One Deck/Upfader in "Deck 1-4 Mode"

Important Note for Windows Users:

Deck 1-4 Mode Not Supported on Windows:

On Windows computers, it's important to know that you cannot use the Deck 1-4 Mode. This is because Windows has a limitation with Midi Devices that prevents them from supporting multiple programs at the same time. As a result, you won't be able to Midi Map your up faders to the SoundSwitch Software while simultaneously controlling Serato. 

Use Deck 1-2 Mode Instead:

To work around this limitation, it's recommended that Windows users use the Deck 1-2 Mode exclusively. This mode does not require Midi Mapping of upfaders and will ensure proper functionality without the issues associated with Deck 1-4 Mode on Windows.


When using "Deck 1-4" Mode and experiencing fixtures responding to only one Deck/Upfader, consider the following:

1. Midi Map your Upfaders on your Mixer or DJ Controller to the SoundSwitch Faders in the SoundSwitch Software.

   - Note: Using "Deck 1-4" Mode is not possible on Windows due to a limitation with Midi Devices. Use "Deck 1-2" Mode instead.

   - Midi Mapping is only required with "Deck 1-4" Mode; for "Deck 1-2" or "Deck 3-4" options, Midi Mapping is unnecessary.

Before Midi Mapping:

1. Confirm your SoundSwitch Performance Preferences match the recommended settings.

2. Midi Map the Upfaders of your Mixer or DJ Controller to the Software Faders via the Midi > External Mixer page.

Issue 4: Faders Do Not Control Fixtures After Pressing "Link"


Do not use the "Link" option with Serato. It is intended for SoundSwitch Standalone Mode or when connecting to another Link-supported application. Disable the "Link" option and ensure the correct SoundSwitch x Serato connection to resolve this issue.

By following these troubleshooting steps, you should be able to address common SoundSwitch and Serato Performance Mode issues effectively.
