What DJing from a streaming service requires |
|
Loading tracks from streaming services is always longer than loading tracks from the host local storage (computer or smartphone).
Bandwidth needed The higher the audio resolution, the higher the bandwidth needed, and the higher the response time: Audio resolutions
Internet access An ADSL or 4G internet access is needed to stream music in a computer or a smartphone. An optical fiber or a 5G internet access is comfortable to stream music in a computer or a smartphone. If your computer shares the internet bandwidth with bandwidth hungry devices as a TV Set Top boxes, then to avoid latency/audio drops caused by this other device grabbing most of the internet bandwidth, you may
Computer settings If you can do it, use an ethernet (wired) connection to your computer. Wifi is workable, but its bandwidth and response time cannot match with the bandwidth and response time of an ethernet connection.
Wifi is CPU intensive, especially in Windows, so that a Windows computer whose wifi is not disabled cannot be considered as optimized for real time processing as Djing. If you have a home internet network, check the bandwidth of the ethernet switch connected to internet box: a 100-Mbps ethernet switch would be a bottleneck, a-1000 Mbps bandwidth is OK. Computer latency Except for tracks loading and analysis which are really slower from a music streaming services, other DJing operations should be as fast whether you mix local tracks or streamed tracks, so if you feel it seems slower when played tracks from a streaming service, you should make sure you have enough free memory on your computer in closing any background program. If your Windows computer lacks memory, it may use a fraction of the hard disk as a virtual memory, but the memory swap to access this section of the hard disk data is slower than reading data in the actual RAM. |

Control 4 decks in Djuced with 2 DJ controllers |
|
To control 4 decks with 2 2-deck controllers, you must
- control virtual decks 1 and 2 with one controller we call primary controller
- control virtual decks 3 and 4 with another controller we call secondary controller.
Djuced 5 cannot support twice the same controller, you need 2 different models, for example DJControl Inpulse 200 and primary controller and DJControl Starlight as secondary controller. The secondary controller needs a specific mapping to control decks 3 and 4: this mapping is included in Djuced 5.0.8 for P32 DJ and DJControl Compact, and new mappings downloadable from Hercules support website for DJControl Starlight, DJControl Inpulse 200, 300 and 500. Use 2 controllers in Djuced, 1) If the secondary mapping is not included yet in Djuced, copy the xml mapping file
- in Windows, in the folder C:\Users\YourName\DJUCED\midi
- in macOS in folder MacintoshHD > Users > YourName > Documents > DJUCED > midi
2) connect the 2 DJ controllers to computer,
3) run Djuced
 4) In Djuced, go in Settings> Mapping
5) Select the controller you plan to set as secondary controller, and click on Next
 6) Select the mapping for deck 3 4 in the mapping list, and click on OK   7) You come back to Djuced mixing interface, and you see a short pop up screen of the last mapping you have loaded.  8) To avoid any issue, I recommend to close Djuced, and restart it. 9) Then in Djuced, select a 4-deck interface, for example "4Decks Horizontal" for a large screen, "4Decks vertical" for a small screen.  And that's it, you control decks 1 and 2 with the primary controller and decks 3 and 4 with the secondary controller. |

Clean sticky areas on DJ controllers |
|
The rubber paint on plastic surfaces often become sticky after some years (how fast rubber paint turns into sticky layer depends on temperature and air wetness).
The easiest cleaner to remove this sticky paint is alcohol, which dissolves the paint and dries by itself. If the area to clean has no labels or marks (as jog wheel's ring), there is no risk to delete any label with alcohol, so you can use a cloth: - choose a soft non abrasive coth - pour alcohol on the cloth - rub the sticky area with the cloth. If the area to clean has holes difficult to reach, then you may use a soft toothbrush - make sure the toothbrush bristles are soft - pour alcohol on the brisles - gently rub the sticky area with the toothbrush. Il the area to clean has also some labels, as the alcohol may delete the labels, you can use Q-tips: - pour alcohol on the cotton of the Q-tip, - gently rub the sticky areas with the Q-tip in making sure the Q-tip avoids the labels. You may also use WD-40 or hydroalcoholic gel instead of alcohol.

Clean a fader on a DJ controller |
|
| Faders are the most fragile part of any DJ controller, so one must be very careful when cleaning them. One must never rub the carbon track (called taper) on the ground of the fader, so one should never touch it. If a fader has dust or rust particles, on should: - take a blow off air duster with a thin straw - put the straw in the fader without touching the ground - blow off any particule - then take a vacuum cleaner and try to grab all these dust or rust particles. |

Vegas Mode / Light animations on Hercules DJ controllers |
|
| When pluging the DJ controller to a computer, the lights of the controller switch on and off to form a light show called Vegas Mode. It shows which keys are backlit, it animates your booth in a party when you stop DJing, and it can also be used in your Youtube videos. Here are the controls to start the Vegas Mode at any moment: Instant (and short) Vegas mode
Non Stop Vegas Mode
