You can set up to 8 Active Loops per track. These can be created in either Engine DJ Desktop by right-clicking on a saved loop button and selecting 'Active Loop', or directly on the device by holding down the LEFT PARAMETER button and pressing the saved loop pad you would like to make active – this action can be toggled to make the active loop a saved loop again. 

Yes, Active Loops can be set from the desktop software as well as Engine DJ hardware.  To assign a Saved Loop as an Active Loop, hold the left parameter button and press the desired Saved Loop pad.  Active Loops feature a striped pattern in the loop region while normal Saved Loops are solid. Please note that setting Active Loops on hardware requires physical parameter buttons.

Yes, but the drive must be migrated to the Engine DJ 2.0 database first in order to mix.  Not to worry, the migration process is automatic and initiated the first time you connect an Engine Prime drive to a device running Engine DJ v2.0.  Your original Engine Prime collection will remain intact in case you need to perform on earlier versions of Engine OS.

The migration process time can vary depending on the size of your collection size and drive speed. For larger collections, it is recommended to use Engine DJ on the desktop to perform the migration process. On average, you can expect the upgrade to take ~20sec for 1000 tracks (12 GB of data) when upgraded on Engine OS hardware. The same-sized collection on the desktop takes ~5 seconds or less. Note: The test above was performed on an SSD drive. Your results may vary depending on collection size and media device read/write speeds. The upgrade migration process is only required once per drive or Engine Library.

Simply open Engine DJ and insert your Engine Prime drive. The migration process happens automatically.

No. After the upgrade process, tracks will not need to be reanalyzed. All of your tracks will still have their waveforms and all other performance data such as hot cues and loops intact.

As of Engine DJ v2.0, Crates and Playlists have merged into a single list type — Playlists. Engine DJ Playlists offer the best aspects of both list types.  During the migration upgrade process, your Crates will be converted into Playlists preserving all the content and structure. Now with Playlists, you can freely rearrange the lists within the collection tree and also the tracks within them.

Yes. Engine DJ v2.0 brings a number of upgrades to streaming services. This includes their inclusion in History playlists, the ability to preview songs prior to loading, songs can be added to the prepare folder, and playlists from streaming services can participate in the new standalone controller Playlist Deck with automated cross-fading.

Yes. The XML export feature returned in rekordbox v6.3.0, allowing you to import your entire library into Engine DJ while maintaining playlist structure, hot cues, and loops.  With Engine DJ v2.0, you can also select which type of cue you’d like to import — Memory Cues or Hot Cues. In addition, you can quickly import your entire collection tree by right-clicking on the rekordbox collection list, and choosing ‘Import Collection’.

Engine Lighting by SoundSwitch is embedded lighting control for DJ's. In the past, you needed to connect your DJ system to SoundSwitch on a computer via Ethernet, however, with Engine DJ v2.0 that is no longer required. Music and lights are automatically synchronized with just the unit itself. Plus, Engine Lighting features its own touch interface to give you real time control over several lighting effects. The Basic version of Engine Lighting Basic can be used with Philips Hue Smart Lights for free while, Engine Lighting Pro requires SoundSwitch hardware and an active free trial or paid subscription.

Engine Lighting requires a SoundSwitch branded USB to DMX interfaces such as the Micro DMX interface or the original SoundSwitch DMX box.

No. At this time, either the X1800 or X1850 mixer is required to use Engine Lighting with the SC5000 or SC6000's.

For full Engine DJ v2.0 compatibility, the X1800 and X1850 also require firmware updates.  Please visit Software downloads, manuals, and documentation - Denon DJ to download the latest firmware update.

By default, the Zone output offers an additional audio stream of the Master output signal.  To send an independent continuous mix: First, ensure the view mode is set to vertical view by pressing the Shift+View buttons.  Tap Browse from the touchscreen and, choose a Playlist you'd like to send to the Zone.  From the top of the Playlist, tap Play as Playlist. This will assign the Playlist to deck 4, and the Zone Assign button will illuminate dimly.  Now, when you press the Zone Assign button, deck 4 will play the playlist in the Zone output independent of the Master output. 

The MCX8000 is not compatible with the new Engine DJ v2.0 database. MCX8000 users should continue using Engine Prime to prepare their drives. Please see the MCX8000 download section to download Engine Prime.

If you receive a database corrupt message after updating, it generally means the database is corrupted. In some circumstances, it is worth attempting to migrate your library again. To do this you will need to delete the 'Database2' folder located locally and on any external drives, you use to maintain your Engine Library. To delete the local Engine 2.0.0 library, ensure Engine DJ application is closed, navigate to Music > Engine Library > Directory, then delete the Database2 folder. To delete a library on the external drive, again first ensure Engine DJ application is closed. Navigate to the root directory of the external drive, open the Engine Library/ folder, then delete the Database2 folder. Now you can start up the Engine DJ application again, and doing this will attempt the migration again on application startup. If the corrupt message persists after the second migration attempt, please take note of the drive name stated in the corruption message, navigate to that drive, and zip all files within the directory except the Music folder.  Upload the zipped folder here. This will assist our team in investigating the issue further. Until this issue is resolved, you can roll back to v1.6 or rebuild your Engine Library in Engine DJ v2.0. Previous versions can be downloaded from the Release Notes section of the relevant release on the Downloads page.

If you receive the error “Your Music folder can’t be accessed” while opening Engine DJ on a Windows computer, this likely means that your music folder is not write enabled, or Controlled Folder access is enabled on the system. The Controlled Folder access feature in Windows can be enabled or disabled entirely, or set to only protect specific folders. In order to allow access for Engine DJ, you must disable the feature or remove your account’s music folder from the protected folder's list. For more details on using and changing this Windows feature, please refer to the article below: Enable controlled folder access | Microsoft Docs
