Storage & Media

What options do I have to connect external drives and other storage devices to the PRIME 4 +?

The PRIME 4 + features (4) USB ports (2 on the top, 2 in the back), as well as (1) SD card port, and an internal hard drive bay to store an optional 2.5" hard drive or SSD.

Note: A hard drive/SSD is not included with PRIME 4 +. Drive must be purchased separately. 

What types of media should I use?

When choosing a portable USB drive or SD card for your PRIME 4 +, we recommend using drives from reputable media brands whenever possible. SD cards must be Class 6 (c6) or faster. USB drives should have similar performance specs (at least 20MB/s read / 6 MB/s write speed). The faster the media, the faster tracks can load. Slower drives may result in lags when navigating through the collection and longer load times.

What size hard drive can I install into the PRIME 4 +?

The PRIME 4 + supports a 2.5" SATA hard drive; either HDD or SSD. There is no drive capacity size limitation, just be sure the hard drive is formatted in one of the supported file system types; FAT32 or exFAT.

What drive formats are compatible with the PRIME 4 +?

All storage media connected to the PRIME 4 + should be formatted to either FAT32 or exFAT with an MBR (Master Boot Record) style partition structure. For larger file systems (1TB and greater) we recommend formatting drives to the exFAT format.

What file formats are compatible with the PRIME 4 +?

The PRIME 4 + and accompanying Engine DJ software support the following audio formats:

  • MP3 32 kbit/s - 320 kbit/s + VBR
  • M4A / AAC
  • MP4
  • OGG Vorbis
  • WAV 16-32 bit, 44.1k - 192k 
  • AIFF 16-32 bit, 44.1k - 192k
  • FLAC
  • ALAC


Do I need to disconnect the internal hard drive to transfer my tracks or database?

One of the great benefits of an internal hard drive is the easy connection and transfer of data back and forth with your computer. Simply connect the PRIME 4 + to your computer and the internal HD will appear as a removable drive for access through Engine DJ and other software.

Before installing your drive, please make sure that your drive is formatted accordingly. 

To access the drive:

  1. Connect a USB cable to the USB B port on the PRIME 4 + and the other end to your computer.

It can also feature track artwork and even your brand logo as a backdrop.

How do I load my custom DJ or brand logo to the center jog wheel display?

To add your own custom DJ or brand logo simply create a .PNG file, name it "logo.png" and place it into the Engine Library directory on your USB/SD media device. We recommend a .PNG with the dimensions of 600 x 600 pixels.

This could also be used to customize a client experience by adding event specific images to the display like a corporate logo or picture of the bride and groom.

What can I do with the performance pads?

Hot Cue - In Hot Cue Mode, you can use each pad to jump to an assigned hot cue point. 

  • To assign a hot cue to a pad, press an unlit pad at the desired location in the track. The pad will light up when a

hot cue point is assigned. 

  • To jump to a hot cue point, press the corresponding pad.
  • To clear a hot cue from a pad, press Shift and the desired pad. The pad will turn off when there is no hot cue

point assigned to it. 

Tip: You can use the Engine DJ software to set, name, and assign colors to your hot cue points. The names and

colors will appear in the display for reference.

Loop - In Manual Loop Mode, you can use each pad to enable an assigned loop. Pressing Loop for the first time will always enter Manual Loop Mode.

  • To assign a loop to a pad and enable it, press an unlit pad to create a Loop In point at the current location, and

then press it again to create the Loop Out point at another location. You can also assign an auto loop to a pad

by pressing an unlit pad while in the auto loop. The loop will activate immediately, and the pad will light up.

  • To enable a loop, press the corresponding pad. Once a loop has been created, you can also retrigger it by

pressing the corresponding pad again, depending on the Saved Loop Behavior setting in the User Profile.

  • To enable an active loop, press and hold the Parameter button and press a pad with a saved loop. Active

loops will begin looping automatically as soon as they are reached, and are shown with a striped pattern in the

track waveform. You can also set these in the Engine DJ software.

  • To delete a loop, press Shift and the desired pad.

In Auto Loop Mode, you can use each pad to create and activate an auto loop. Pressing Loop while in Manual Loop

Mode will enter Auto Loop Mode.

  • To activate an auto loop, press a pad. The display will show the length of the auto loop for each pad.
  • To deactivate an auto loop, press the pad again.
  • Use the parameter buttons (</>) to increase or decrease the length of the loop. 
  • Hold Shift and use the parameter buttons while a loop is engaged to shift the loop region forward or backward.

Tip: You can use the Engine DJ software to set and name your loops. The names will appear in the display for


Roll - In Roll Mode, you can press and hold each pad to trigger a "loop roll" of a certain length while the track's timeline continues (the lower half of the waveform in the display will continue moving forward). When you release the pad, the track will resume normal playback from where it would have been if you had never done anything (i.e., as if the track had been playing forward the whole time).

  • To trigger a roll, press the corresponding pad. Pads with triplet-based loop rolls are indicated are lit with a different color.
  • Use the parameter buttons (</>) to increase or decrease the length of the roll.
  • Hold Shift and use the parameter buttons while a loop is engaged to shift the roll

region forward or backward.

Slicer  - In Slicer Mode, the eight pads represent eight sequential beats "slices" in the beatgrid. When you press Slicer, you automatically activate an eight-beat loop. When you release the pad, the track will resume normal playback from where it would have been if you had never pressed it (i.e., as if the track had been playing forward the whole time).

  • To play a slice, press the corresponding pad.

In Slicer Loop Mode (second press), the eight pads represent eight sequential beats "slices" in the beatgrid. The

currently playing slice is represented by the currently lit pad; the light will "move through the pads" as it progresses

through the eight-slice phrase, which will loop (this is the difference between this mode and Slicer Mode). You can

press a pad to play that slice. When you release the pad, the track will resume normal playback from where it would

have been in the loop if you had never pressed it (i.e., as if the track had been playing forward the whole time).

  • Use the parameter buttons (</>) while a slice is engaged to increase or decrease the length of the slice.

Sampler -  In Sampler Mode, you can assign and trigger up to eight samples using your performance pads*. You can view your assigned samples in Performance View by enabling the Performance Pads widget in the Control Center. When the Sampler pad mode is selected, you will see the sample names loaded to each pad in the slots below the track overview waveform.

  • To load a sample from Library View, swipe the sample to the right, or double-tap the sample. Next, instead of

selecting a deck, tap one of the eight sampler slots on the touchscreen. Alternatively, press the hardware pad where you want the sample assigned. If a sample is already loaded to the selected pad, the new sample will replace the existing sample. Loaded samples will be retained in memory across device reboots and changes in Source drive selection.

  • To trigger a sample, press the performance pad on the hardware. The sampler volume can be adjusted using the Sampler Volume slider in the Control Center. Sampler audio routing can be adjusted using the Sampler Output option in the Settings menu.
  • To stop a playing sample, hold Shift and press the performance pad.
  • To remove a sample, you must first exit Performance View. 

Samples cannot be removed while in Performance View to prevent accidental ejection. While in Library View, Settings, or another page, press and hold Shift then press the performance pad with the sample you want to remove. If the sample is playing, you will need to stop it first, then remove it.

*Prime 4 + includes a set of pre-installed sample content, which you can browse from Library View when

Sampler Content is selected as a source. You can enable or disable this content from appearing using the Sampler

Content setting under User Profile.
