Hi. I'm in a bit of a dilemma. I've a DJ competition coming up next week and the tempo fader on the left side of my S4 mk3 has started to glitch and jump in tempo constantly making it impossible to mix without the sync button. I was going to send it to NI to get repaired but I'm in the UK and there's no chance it'll be back to me in time. I did see an S2 MK3 going cheap on eBay and was wondering if the parts for the tempo faders would work in my S4? I was hoping I could fix it myself. Does anyone know if this would work? Or does anyone know why my tempo fader is jumping about and maybe have suggestions for an easy fix? Thanks for your help in advance 😊
