Having 'ghost midi' jitter issues.

909kang

I seem to be having a huge issue with a Komplete Kontrol S-49. MK2 keyboard I bought second hand. The MIDI values adjust themselves and cause huge problems in the software as the UNDO menu gets filled with the (ghost) movement of the knob.

I uploaded a YouTube hope someone can help me sort this out. On the hunt for the correct pot.

I have removed the part but still the problem persist.

There is some info in the description as well.

Part number says 0b20k 20F3

It has 4 prongs on the front side and 2 (one on each side) for the sides.

seem to be over one inch long (maybe 28 mm ?) with a flat shaft.

see video... hope some one knows a solution for me ;)

Are you sure there isn’t any recorded automation involved? Is this happening in every project or just one?

909kang

every project and also it will hog up the UNDO in Ableton live just the same.

It will record the ghost movements when using AUTO in Maschine as well. there for creating two automation lanes instead of just the one for the knob I as actually moving.

Can you post a screenshot of the Ableton midi preferences?

That knob looks like it is at least 5mm pushed/slammed into the unit. Connect the unit to a midi monitor to inspect signals but it looks like you will need the replacement encoder.

That’s not the case the knob has been removed and I am awaiting a part being shipped. The knob is just dummied up so it looks sunken.

I will try to look at things in a midi monitor as well for clues thanks.

I have ordered one of these.. seems like the exact one.

someone else on eBay is selling used M-Studio pots that look the same as mine as well.

It’s not about Ableton it happens in Maschine as well. I have a good working KK 49 MK2 and it doesn’t do it even with the same preference in MIDI chosen. I have 2 keyboards (KKS49 MK2) exactly the same but one freaks out and one doesn’t. So I know it’s not software or a computer issue.

There is no extra automations involved as it happens with a blank new project every time.

It sounds like a hardware defect. Have you already opened a ticket with NI support?

909kang

yes I have

909kang

Yes I have but another week rolls by and I haven’t yet heard back from them.

So too late now as I waited for a response from support I was able to order a knob from China wait two and a half weeks and figure out how to open up the KK49 pull it apart and solder in a new knob.

It worked and it fixed my ghost producer issues of the invisible man standing behind me and twisting the knob when I was t looking 👀.
