CDJ Deck Playing track up to + 20% Pitch in Traktor

When I'm set up at home using Macbook Pro & Traktor Scratch Pro 2 (all latest versions) with 2 x CDJ1000s I can start playing straight away.

However, the last 3 times I’ve played out (all different CDJs) one of them will often default to playing 1 deck at +20%, sometime much higher.

Luckily I’ve had my Kontrol X1 with my so I just use that though I want to be able to control with CDJs.

Anyone had this issue or know how to help?

I assume you're using control CDs, have you recalibrated them? What sound card are you using?

Yes I'm using Cd controllers on CDJ 1000s, I'll try that and see how it works

Yes they are calibrated fine but as I said in my home set up I never get this problem only when Ive been in a club or radio studio.

which audio interface are you using?

Audio 10 - all brand new (4 weeks Old)
Running on Macbook Pro (2009) 500GB drive / 8GB RAM
Pioneer CDJs-1000
Pioneer DJM-800 Mixer

Also use a Traktor Kontrol X1
