Xiaomi Mi Pad 4 not working with DDJ SB

[kairosooo]

Tablet: Xiaomi Mi Pad 4
OS: Android Oreo w/ MIUI 10.1
DJ App version: Cross DJ Pro v3.3.5
Controller: DDJ SB

I followed everything on the official YouTube connection tutorial, doesn't work. Problem listed as below:
1. The controller is lit up, means there is power, but is not recognized.

2. In app, there is no any "Connect MIDI" button to press.

3. I have already unlocked Developer Mode and tried the MIDI connection option, still doesn't work.

Seeking any help, thanks.

Hello kairosooo,

Sorry that you are having issues getting the DDJ SB to work on your device!

On newer Android versions MIDI should be plug-and-play so there is no longer a MIDI connect option in the settings, like shown in the YouTube video. Sorry about any confusion!

Check to make sure that you have the DDJ SB and powered USB hub connected and powered on before launching Cross DJ (if it is open in the background force close it first). Sometimes there can be connection issues if you connect after the app is open.

Let me know if that isn't it!

Mi has not made any changes in the application and thus we are facing issues with the application. We can troubleshoot the issues by the tips given by *LINK REMOVED BY MODERATOR*

Mi Pad 4 64+4 Wifi could not recognize any MIDI device
I have already tested the device in both MIUI and Stock Android, adjusted developer mode USB connection settings, still cannot work.
I tried on a Google Pixel and it worked flawlessly, I saw two posts in official MIUI forum reporting the same problem too, so I guess this is a hardware problem? Maybe XiaoMi has to do some update patches to enable the function?
