Fixing dead keys on an Akai MPK Mini (and not just cleaning the circuit board)
I wanted to use my old MPK Mini MIDI keyboard today but when I plugged it in it had 4 dead keys. Cracked it open, cleaned it up, fixed some faulty contacts, and it works flawlessly again. Too bad I didn't feel like making music anymore once I'd finished repairing the keyboard.

    at 3:12: to remove the connector tape, you have to push the 2 little black levers from that small black thingy you got into your hands. using a small flat screwdriver, simply push a little bit those 2 black thingies in the same direction you want to remove the connector. the black plastic thingy only "pushes" the tape to block it. it's not "clickable"

    It's not clear to me (or perhaps I just missed it) but when the crazy glue didn't work, did you just stick the copper tape pieces to the carbon surfaces with nothing more than their sticky back? Or did you find a better way? I'm suspecting that after a short while of use, they would just fall off as there's no pressure to keep them in place. So I'm wondering if anyone has tried a better method to adhere these pieces? I haven't tried it as my MPK is working just fine, but I have some remote controls that use the same membrane to carbon contact method, that I need to fix. So as for the copper tape, I wonder if removing the sticky from the back, then using a small rotary tool bit, very fine and removing all that carbon contact surface on the membrane, would then allow the cop to be crazy glued or perhaps some other type of glue, might work. I'm not sure the best method of removing the sticky back from the copper, but there must be some chemical that we could use to soak it. I'll have to check, but I suspect that I bought a roll of copper tape that doesn't have a sticky back. If so, then this is a moot point. Then I only have to consider the best way to gently remove the carbon coating from the membrane. I'm' thinking that with bare copper to bare membrane material (I'm not sure if that's real rubber or some other stuff), it might be easier to glue the copper pieces so they'll remain flat and stick without falling off. Has anyone come up with a way to do this that works? As for the copper, when I do this, I'm going to see if either a hole punch will make perfectly shaped contacts, but if too big, perhaps using my leather hole punch as it has different sizes and even different shapes. There has got to be a way to fix these types of contacts!

    Important note: After you finish this CYK algorithm, if the starting symbol of the grammar (in this case S) is in the top-row (last row) of our procedure, then the given input string is part of the grammar, otherwise it is not. In this case S is part of {S, A, C} which means that the given input string "baaba" is part of the grammar defined by the production rules. The time complexity of the CYK algorithm is O(n^3) where n is the length of the input string (in this case "baaba", so n=5).

    can I use the rubber piece that lies on the circuit board (I believe it's called a contact rubber, but I'm not sure) for the MPK261 as well? I've had an AKAI MPK261 sitting with me for about half a year, but I can't use it because the rubber is torn and brittle. for months, I've been searching for replacement parts but can't seem to find anything. therefore, i'm curious if the rubber from the smaller MPK models can be installed into the larger version...

      I know that your post is over 3 months old and you've probably already discovered that this will probably not fit. But, by any chance, do you have a 3D printer, some Flexi filament and the ability to use a CAD program, like Fusion 360, for example, to design a replacement that might work? Just a thought.

That's a conductive spray paint that is sprayed on a CRT's bell so that a grounding spring can lay across it. That stuff works so well, but I can't even find it anymore. I'd love to see if that would be an option as it does stick very well.
