What Engine DJ hardware is stems compatible with?
In November 2024, the PRIME 4+ gained the ability to play stems, a feature included at no additional cost for this flagship model.
Starting in December 2024, stems playback will also be available on all other compatible hardware via a one-time license purchase.
How can I unlock the stems feature on Engine DJ hardware?
For PRIME 4+ customers, the stems feature is automatically unlocked on the hardware after updating to Engine DJ OS 4.2.0.
For other Engine DJ hardware, a license will need to be purchased. Once purchased, simply sign in to your Engine DJ Profile on the device to unlock stem functionality.
Note, that stems need to be rendered in Engine DJ Desktop before they can be played back on Engine DJ hardware.

PRIME 4+ customers receive the stems feature for free.
Starting in December 2024, all other customers will be able to unlock stems via a one-time license purchase of $9.99 (USD). You can purchase an Engine DJ Stems license through your inMusic Profile by visiting the link below:
How do I prepare my tracks to use the stems feature on hardware?
Stems are rendered in Engine DJ Desktop 4.2.0 onwards. To render stems, use one of the following workflows:
Right-click a track or multiple and choose ‘Create stems’.
Drag and drop a track, multiple tracks, or an entire playlist onto the Stems list.
No license is required for stem rendering on Engine DJ Desktop.
How do I use the stem pad mode on my Engine DJ hardware?
Pad 1 = Vocals
Pad 2 = Melody
Pad 3 = Bass
Pad 4 = Drums
Pressing a pad toggles its corresponding stem part on or off. If the pad's LED is lit, the stem part is audible; if the LED is off, the stem part is muted. By default, all stem parts are enabled and audible.
Is there a way to quickly activate an Acapella or Instrumental?
Left Parameter = Acapella
Right Parameter = Instrumental
How do I know when a track has been rendered for stems?
On Engine DJ Desktop, there is a new stems column in the track list that shows you the three possible statuses’':
A circular spinning animation in this column means tracks are actively being rendered.
A Gray stems icon in this column means tracks are queued to be rendered.
A White stems icon in this column means that these tracks have been successfully rendered and can be played back on Engine DJ hardware devices.
On Engine DJ hardware, a White stems icon is shown to the left of the track title. This icon appears in the track list as well as the deck info area once loaded to a deck.
On both Engine DJ Desktop and Engine DJ hardware, a Stems list is now shown for easy discoverability of tracks with stems.

Stem playback is only possible on compatible Engine DJ hardware.

How much space will rendering stems use?
When rendering stems, you are creating additional stem files for playback of four parts of audio separation. We recommend ensuring you have a minimum of 5GB space as per the system requirements for Engine DJ Desktop.
Please ensure you also have enough space on your USB, SD or internal HD (on your Engine DJ hardware). In any case where remaining drive space is low, we recommend upgrading to an external drive with larger storage capacity.
I’m running low on external drive space, can I pack tracks without their Stems?
No, but you can remove stems from a track on an external drive using the right-click option “Remove stems from Drive”. In any case where remaining drive space is low, we recommend upgrading to an external drive with larger storage capacity.
How do I remove stems files without deleting the original track?
To remove stems files from individual or multiple tracks, select them from the track list in Engine DJ Desktop, right-click and choose “Remove stems from Collection” or “Remove stems from Drive”.
Why aren’t my file/s rendering stems in Engine DJ Desktop?
If you are experiencing any issues when rendering stems in Engine DJ Desktop, please ensure that:
The audio files in use meet the system requirements for rendering stems in Engine DJ Desktop stated in the Engine DJ Desktop 4.2.0 User Guide.
The drive in use has enough spare capacity for rendering stems in Engine DJ Desktop. In any case where remaining drive space is low, we recommend upgrading to an external drive with larger storage capacity.
Why are the tracks in my Stems list taking a long time to show?
You may find that the Stems list is slow to load when accessing the Stems list on a device for the first-time. This is a known behavior that we hope to address in the near future.
Can I use stems from a drive connected over a network connection?
Yes. Please note that there is a known issue with the speed of the Stems list presentation that impacts drives accessed over a network connection too.
