M32 replacement knob caps

Wilmar Boer

I'm looking for replacement caps for the knobs on my M32. One knob broke, And I like to use colours to distinguish between the first set if 4 and second set of 4 knobs.

Does anyone know of any knob replacement that won't break the touch sensitivity of the knobs?

Electrically conductive colored caps aren't very common, the best might be buying some solid aluminum caps (the ones with no plastic inside that require grub screws) like this:

You can find those at ebay, aliexpress, etc... However, I think the process used to color them is anodization which creates a layer that breaks the electrical conductivity but I am not 100% sure.

MPCstuff sells this: https://www.mpcstuff.com/billet-silver-anodized-red-gold-chrome-knob-for-akai-mpc-mpd-mpk-force-maschine/ - they claim it's "compatible with Maschine" but I have my doubts about the capacitative touch functionality due to the issue mentioned earlier, also they don't seem to be the D shaft type so I would definitively email first and clarify those things. (I guess the D shaft problem is solved by the screw assuming its long enough)

If going with a DIY approach is OK with you then order a cap set from NI and spray paint them with electrically conductive paint, it should work but no guarantees, this might be a pricy solution tho.

I guess you could also consider a sticker that only cover part of the cap, I have these dot stickers laying around that fit perfectly but obviously will look a bit guetto.
