Working with the Opus Quad
Even though the Opus Quad does not attempt to truly implement the Pro DJ Link protocol, it is now possible to use many Beat Link Trigger features with that hardware thanks to a lot of work by @cprepos and Kyle Awayan.
The key to getting useful results with the Opus Quad, since it is unable to send most of the metadata that BLT needs, is to create metadata archive files for any USBs that you want to use, and attach them to the appropriate USB slots in the Player Status window.
| We don’t yet support running BLT and an Opus Quad with tracks loaded over Link from Rekordbox or Rekordbox Mobile. We hope this can be solved before the formal release of 8.0, but are not yet sure how practical it will be. |
Creating Metadata Archives
To create a metadata archive of a USB that you want to use with the Opus Quad and Beat Link Trigger, start by mounting that USB on the computer running BLT. Then choose in the Triggers window.
This brings up a window where you can navigate to the mounted USB drive:
Once you have selected the mounted media, click Choose Rekordbox Media. That opens a new window where you can choose where to save the archive:
Navigate to where you would like to save it, choose a name for it, and click Create Metadata Archive. The archive will be created, which may take a while, depending on how many tracks are in the USB. A progress bar will allow you to see how the export is going, and cancel it if you change your mind:
Once you have archives created for all the USBs you want to use with your Opus Quad, you can proceed to the next step.
| You will need to update your metadata archives whenever you add or remove tracks on the USB. To do that, follow the same steps above, choose the existing archive that you want to update at the step where you are specifying where it should be saved, and respond Yes to the dialog that asks you if you want to replace the existijng file. |
Attaching Metadata Archives
Whenever you insert a USB into the Opus Quad, you need to attach the corresponding metadata archive for that slot number. To do that, use the gear popup menu corresponding to that slot in the Player Status window (this uses the same user interface elements that would be used to tell players to load or play tracks with other hardware):
Navigate to where you saved your metadata archives, choose the correct one, and click Attach Metadata Archive:
This will enable Beat Link Trigger features to operate when you play tracks from that USB. If you ever swap the USB in the slot, you will need to go through this process to switch to the correct archive for the new USB that you have inserted. If you have removed a USB and do not plan to insert a new one, choose Remove Metadata Archive in the gear menu for that slot.
| Make sure you are using the gear menu for the correct slot that you are inserting or removing USBs in the Opus Quad, and that you choose correct and up-to-date metadata archives for those USBs, or track matching will not work correctly! |
