MIDI Controller not recognized

[Slak_Jaw]

Hi @N_C, glad you got it sorted out. Yeah, one of the first things to try whenever you experience any unusual behavior is a Forced Restart of your iOS device:

1. iPhone: Force restart iPhone - Apple Support (IE)
2. iPad: Force restart iPad - Apple Support (IE)

Regarding this

@N_C

Crossfader (DJay app) is twitching & causing interference on main output speakers on this set up I think this is related to controller connected to mains.

I would try the following:

1. Clean the crossfader using a can of compressed air to remove any dust or debris.
2. Make sure you are using a high quality USB cable with dual ferrite magnets on either end to ensure there is no interference in the data transmission (DJ TechTools makes USB cables specifically designed for DJing).
3. Connect your power supplies to a high quality surge protector and try a different power outlet. Alternatively, try powering the Buddy with a power-bank battery.
