My DDJ - SP1 functions fine when attached to my Windows 10 laptop and latest rekordbox DJ Performance Mode via USB. As soon as I switch on my DJM 900 Nexus 2 mixer however the SP1 loses access to FX side 2 (i.e. It greys out on screen and I can no longer highlight/activate the 1 & 2 buttons on it. I can still see the rotary pots responding at the top and I can click each one on and off but none of the effects work on Deck 2. I can select Decks 1 or 2 (or both) for FX 1 and they work however that just limits me to one bank of 3 effects within the software.
This happens when the mixer midi light comes on. Its almost like there is some form of conflict between the Midi of the mixer and the midi of the ddj-sp1
Is this a known thing ? Is there any form of fix/workaround ?
would love some help from more knowledgable guys from this forum or indeed any Pioneer rep
