The motorised fader on my CC121 died a death a while back. I since came across a post with someone who had replaced theirs with a Yamaha LS9 fader from the Thomman web site and he said it worked fine, so i decided to order one and repair my CC121 myself as the unit is over 10 years old. Everything works as normal apart from the fader tracking/calibration is messed up. When i move the physical fader, cubase volume follows perfectly. if i move the fader in cubase, the physical fader only starts from 1 quarter way up to 3 quarters from the top is is very jerky in between. I’ve since noticed there are actually 2 different Yamaha LS9 faders for sale on Thomman. Neither of them mention being compatible with the CC121 but I bought the one that says its suitable for Yamaha LS-9, M7CL, CL1/CL3/CL5 So maybe i bought the wrong one or should they both work fine? The one i bought looked identical to the broken one i took out apart from it has a rubber dust seal under the moving fader part. > **[Yamaha LS9 Motorised Fader New](https://www.thomann.de/gb/yamaha_ls_9_motorised_fader_new.htm)** > > Motorised Fader Suitable for Yamaha LS-9, M7CL, CL1/CL3/CL5 (mixer), With dust protection lip - NEW model, Enclosed The other one says its compatible with 01V96, DM1000, DM2000, 02R96, M7 Anybody have any expertise in this?

I had the same exact issues with my CC121 right out of the box and it wound up being a bad power supply. ---

Same about me: I have changed the power adaptor and the problem was solved. ---

I have had this problem out of the box too, i thought the fader just wasnt very good but then recently i saw user videos that were working flawlessly and realised i had a problem. What replacment did you get? Is it possible to get a UK 3 prong plug one? thanks! ---

[CC121 Replacement fader problem](https://forums.steinberg.net/t/cc121-replacement-fader-problem/159018)? I ran into the same problem after buying a used CC121 with a defective fader (the sense line was disrupted, so moving the fader would no longer update the virtual fader in Cubase). Searching for a replacement part, i came across the same two YAMAHA faders that have been discussed here and that are currently offered by thomann, one with a rub…
