7 of the 11 knobs were constantly sending random control changes, even when not being used, and several of the buttons needed an extremely hard press to work (mute, solo buttons, etc.)
for the buttons, i thoroughly cleaned all the contacts on the board with alcohol, as well as the "black small things" on the rubber buttons themselves (what touches the board, when pressing the button). this worked extremely well, except for 2 buttons (control and step). considering there is no physical switch here to replace, is there anything i else i can do? just try again? does anybody know of a hack, maybe putting a small peace of rubber (or whatever) between the buttons and the board? I'm honestly a bit lost
regarding the knobs, after reading a bunch on here and old NI forum (wayback machine), with maschine open, i cleaned (between) the potentiometers with a peace of paper and dental floss, and this worked surprisingly well. some knobs are still a bit faulty, but now it's about 3, not 7, and the changes seem a lot less. i will re-do this process (ran out of dental floss lol), but should some potentiometers still need replacement after, do the RV112FF-40B1-15F-0B20K-0068 work on MK1 as well? these seemed to be the potentiometers to get, based on the forum's consensus, even tried by D-One, however, i could not understand if these would work on MK1 as well.
If anybody has any input on any of this, i'd highly appreciate it. i think i need to take care of the buttons first anyway, since without these, working knobs are still useless. but if there is hope for the buttons, maybe there is a chance with the knobs as well?
