It turns out my DDJ Ergo was faulty since I bought it and it’s been sent back to Pioneer! I had no idea, it was a demo model and now I’ve wasted all this time getting it set up. Both Pioneer and the online shop confirmed that if a parameter, eg, the gain is moved and nothing changes in the software till you move it drastically to get a response, it is in fact faulty. I’m considering whether that was their quick way of passing the puck and not having to go into technical detail with me, & whether it will return as no fault found, but I’ll just have to wait and see. Apparantley, they say it must be faulty if I’ve struggled for 2 months with no luck. What a pain though, I have gigs booked, 2000quid spent on the set up and no time to practice after it’s returned, bugger! Oh well, I’ll be the old Daddy again with vinyl at the festivals this year. Oh yeah, I tried rolling back to the previos version and couldn’t find any option, or instruction on how to, but found out it was faulty before I had rolled back, thanks for your suggestion though. Could you let me know if you have any luck with the later version of Traktor? Cheers
