Engine DJ | Issues and Solutions

Engine OS-enabled devices (Denon DJ Prime series, SC Live series, and Numark Mixstream Pro) are not currently supported for use with WPA3-enabled Wi-Fi networks. Attempting to connect an Engine OS device to a WPA3-enabled network may result in a failed connection. For a secure connection, please connect your Engine OS device to WPA2-enabled Wi-Fi networks. In most cases, the WPA protocol can be changed by accessing your Wi-Fi router settings. Please connect with the manufacturer of your Wi-fi router for more details on accessing and changing your Wi-Fi security protocol.  WPA2/WPA3 Transitional or Mixed Modes Engine OS may be able to connect to Wi-Fi networks set to a WPA2/WPA3 "mixed mode". This will allow each connected device to use the protocol it supports.  In order to use a mixed mode, the PMF (Protected Management Frames) must be set to "optional" status. Engine OS devices will not be able to connect if PMF is enabled.

Engine DJ has recognized a potential issue with connecting an Engine OS device (PRIME series and Mixstream Pro) to WIFI hot spots generated by an iOS device (iPhone or iPad).  This is a known iOS issue that Apple has acknowledged. For anyone unable to connect their device to an Apple hot spot, Apple has shared troubleshooting and workaround instructions available on their support site.  Please follow the link below and refer to the "If you can't connect to Personal Hotspot with Wi-Fi" section for troubleshooting and workaround: If Personal Hotspot is not working on your iPhone or iPad (Wi-Fi + Cellular)

Engine DJ is aware of an issue preventing Engine DJ hardware from connecting to Dropbox.  Update: Firmware update v2.1.2 has been released to fix the Dropbox connection errors. If you have been experiencing difficulty connecting with Dropbox from your Engine DJ hardware, please ensure you are on firmware version v2.1.2 or higher.  All current Engine DJ device firmware can be downloaded from the link below.

macOS users may notice that the Engine DJ Sync Manager is unavailable or greyed out when they go to sync files with their drive. Or, they may either have no access to any functions within the sync manager or are unable to access any connected drives.  As is common these days, macOS security options are evolving and the Engine software may need to be enabled permission to access your hard disk and/or external drives before any files can be transferred. If this is not done when prompted during installation (options could have also changed during an OS update), it's easy to go into the macOS system settings and update the permissions.  Navigate to the Apple menu (top-left corner of the screen) > System Preferences Select Security & Privacy, then click the Privacy tab at the top On the left side of the window, find and select Files and Folders. You should then see Engine DJ in the right-side of the window. Click the lock in the bottom left-hand corner of the screen and enter your password before you can make any changes. Once unlocked, place a check in the boxes for Removable Volumes and Desktop Folder beneath Engine DJ. Click the lock again to save your changes. Restart Engine DJ and you should now have full access to the Engine DJ Sync Manager and your external drives. 

Earlier versions of the Engine DJ OS included a crossfader enable/disable setting in the Control Center. However, because the PRIME 2 also features a physical crossfader assign switch on the front, the internal setting was removed in Engine DJ OS v2.1.0.  If the crossfader is disabled in the Control Center prior to performing the update, the crossfader will be stuck in a disabled state.  To correct this, a previous iteration of the Engine DJ OS will need to be installed on the device and the state of the crossfader will need to be changed before upgrading back to the latest Engine OS. Navigate to enginedj.com/downloads and download Engine DJ OS version 2.0, 2.0.1, or 2.0.2 from the list. For your convenience, you can use the links below to download v2.0.2 for the PRIME 2: PRIME 2 v2.0.2 - Windows PRIME 2 v2.0.2 - Mac PRIME 2 v2.0.2 - USB Install the earlier Engine OS. For instructions, please visit the link below: How to Update Engine DJ OS Power on the PRIME 2 and navigate to the Control Center by pressing and holding the View button or swiping down from the toolbar. Tap the X Fader button to enable it. The crossfader is enabled when the icon on the screen is lit up. Once enabled, simply power off the PRIME 2 and update back to the latest Engine DJ OS. The latest version will be available at enginedj.com/downloads. The crossfader should now be functional again. To disable the crossfader in Engine DJ OS v2.1.0 or higher, set both crossfader assign switches on the front to "Thru".

When Engine DJ is reading from iTunes/Apple Music, it is reading from an XML file which is backup system iTunes/AM created for its own database, which allows third-party software (like Engine DJ) to read your iTunes/AM library. If, for whatever reason, this XML gets corrupted by AM or is out of date, you may see such issues like incorrect date added tags, missing files, new files not showing up when added to your iTunes/AM library etc. It is possible that you will have music in your iTunes/AM library that might not appear in Engine DJ. This could be due to a corrupt iTunes/AM XML database. If this happens, what we can do is create a fresh iTunes/Apple Music Library.XML file by following the steps below. 1. Open your default 'Music' folder. 2. Open your 'iTunes' or 'Apple Music' folder. 3. Drag the 'iTunes Music Library.xml' file to your desktop. Open Engine DJ desktop on your computer, click on the gear icon in the upper right corner to bring up the settings menu, select Library and confirm Apple Music Library is ON under Integration. Close the settings menu and click on the Apple Music logo to the left of your screen and then click Update. This should import the brand new XML for use with Engine DJ.  If exporting a new XML file for your Apple Music library does not work, please contact technical support for further assistance. 

Due to recent changes made in Dropbox, users will likely experience issues with missing files in Engine Desktop 3.0.  The fix for this is to use the recently released Auto Relocate files feature in Engine DJ.  Simply right-click on one of the missing tracks in your library, then click Auto Relocate All as shown below.  Once the process is complete, the files should be restored. For further technical support, please join live chat during business hours or open a support ticket.

Due to recent changes made by Apple, some new Mac computers are shipping without Rosetta pre-installed. This can occur on Macs with Mac OS 13 Ventura installed or when running the Mac OS 14 Sonoma public beta.  Rosetta allows older Intel applications to run on Apple silicon processors(M1,M2). If you attempt to download and install current versions of desktop firmware updaters for Engine OS devices, you may be prompted to install Rosetta in order to proceed with updating your Engine hardware.  You may receive a prompt similar to the one shown below:  Click Install to proceed, then you will be able to run the desktop firmware updaters for Engine OS devices.
