Help I can't switch from Stems BETA to Engine

Engine DJ Software Engine DJ (Mac & PC)

Yes, that is the Engine DJ library software. The software of your Prime 4+ is called Engine OS. Your OS is the older Beta version, but you can update it to the latest version. There are several ways of doing this (but I don’t know if the Beta supports updating over Wi-Fi).

The following way to update the OS I know from my SC6000M players and the Live 4, it should work for the Prime 4+ too, step by step:

  1. Go to the download page:

  1. On the right side, under OS, where it says select your device, select the Denon DJ Prime 4+.

  2. Download the updater file, depending on your laptop, for Windows or Mac. The Windows updater file is Prime 4 Plus 4.2.0 Updater.exe, for example.

  3. Launch the downloaded Installer/Updater file on your laptop.

  4. Connect your Prime 4+ to the laptop with a USB cable. The SC6000M has a blue USB cable for this, probably it is the same for the Prime 4+. Switch on you Prime 4+.

  5. On the Prime 4+, swipe down the menu from the top of the screen. If you have not used the Prime 4+ so often, this may be new to you, there is a menu that becomes visible if you swipe one finger from the top of the display to the bottom. There go to Settings.

  6. In Settings, go to the About/Update tab. Find Update Firmware, it should have a button labelled Reboot. Tap on it. On the Prime 4+ you should now see a window asking How do you want to update? Choose Computer. And then the Prime 4+ will enter update mode, the screen will probably show a large Engine DJ Text and a microchip icon.

  7. On your laptop, click the Start Update button in the Installer window. While the update is being installed, do not turn off the power. After the installation the Prime 4+ reboots. And welcome to the future! :blush:

I hope that this helps you and that all goes well. There is also a helpful YouTube video, which shows the other update methods as well:

About the version numbers: The Engine DJ library software (on your laptop) is currently at version 4.2.1, the Engine OS on the players (like the Prime 4+) is at version 4.2.0.

P.s. And maybe some of the other Beta users can confirm this or correct it if something is different in the Beta version.
