FAQ

What do you need help with?

• What is STEMS function?

  This is a function for outputting the sound of a track separately in VOCAL Stem, DRUMS Stem, and INST Stem. ACTIVE STEM, STEM ISO, and STEM FX functions are usable.

  • ACTIVE STEM
    Each Stem is output by setting each STEM MUTE button of VOCAL/DRUMS/INST displayed at the deck Stem to ON. If it is set to OFF, each Stem is muted.
    Click [Preferences] > [Extensions] category > [STEMS] tab > [ACTIVE STEM Setting]. You can select [MUTE] or [SOLO].

  With [MUTE] setting, output / mute of each Stem can be controlled.
  With [SOLO] setting, output of all Stems or output of one Stem can be controlled.

  • STEM ISO
    If you set STEM ISO mode button that is displayed at mixer Stem to ON, the mode shifts to STEM ISO mode in which you can adjust the sound volume of each Stem.
    When STEM ISO mode is ON, adjust the sound volume of each Stem with each knob of VOCAL/DRUMS/INST.
  • STEM FX
    If you set each STEM FX button of VOCAL/DRUMS/INST that is displayed at effect Stem to ON, it is possible to apply an effect to each Stem.

  To activate STEMS function, check-mark [Enable the STEMS function] (Click [Preferences] > [Extensions] category > [STEMS] tab).

• Can STEMS function be controlled by DJ equipment?

  Yes, it can be controlled by DJ equipment on which STEMS function is mounted.

  In addition, you can use each function by assigning it to the hardware on MIDI LEARN.

  However, it is necessary to subscribe to a supported Plan or connect a HardwareUnlock device.

• If you use STEMS function, noise occurs.

  Check the following.

  1. Does your computer fulfill the environmental requirements of rekordbox?
     Check the System Requirements.
  2. Is the buffer size properly adjusted?
     The latency (time that elapses before outputting sound after operating this equipment) can be shortened by setting the buffer size small.
     If audio dropout occurs, increase the buffer size. However, the latency becomes longer.
     Set the minimum buffer size that does not cause audio dropout.
     The buffer size can be adjusted by clicking [Preferences] > [Audio] category > [Configuration] tab > [Buffer size].
     * If DJ equipment is connected, refer to the content shown in the operation manual.
  3. Isn't other application operating?
     Close applications that are not in use including Web browser, Explorer (Windows) or Finder (Mac), screen saver, and resident software once.
  4. You may be able to decrease the symptom by changing the setting of multithread.
     Click [Preferences] > [Extensions] category > [STEMS] tab > [Multi-thread] and deselect [Apply multi-thread to the analysis process].
  5. You may be able to decrease the symptom by turning OFF the following functions with high processing load.

  • • Video function
    • Lyric function
    • MERGE FX

• When loading tracks, a caution “The STEMS function is unavailable since there is not enough free space in the memory.” is displayed.

  Check the following.

  1. Does your computer fulfill the environmental requirements of rekordbox?
     Check the System Requirements.
  2. Is the buffer size properly adjusted?
     The latency (time that elapses before outputting sound after operating this equipment) can be shortened by setting the buffer size small.
     If audio dropout occurs, increase the buffer size. However, the latency becomes longer.
     Set the minimum buffer size that does not cause audio dropout.
     The buffer size can be adjusted by clicking [Preferences] > [Audio] category > [Configuration] tab > [Buffer size].
     * If DJ equipment is connected, refer to the content shown in the operation manual.
  3. Isn't an option for increasing the memory usage for analytical processing activated?
     Click [Preferences] > [Extensions] category > [STEMS] tab > [Memory] and deselect [Increase the memory size of the analysis process].

  In addition, carrying out the following may resolve the insufficient memory space, however, change the setting at your own risk.

  • Uninstall of unused application
  • Deletion of unnecessary files
