Top row of pads don't work, can I fix them? MPC2000xl
I got an Akai MPC2000xl off of Ebay awhile ago. Everything about it works fine except for the top row of pads. It makes me think that the previous owner spilled water on it or something. The top pads work only if you press on them extra hard, and they still usually don't work with the precision that they should. This isn't a necessity for using this machine, but it certainly is inconvenient. Does anybody know how I could fix the four pads, or is it a lost cause?

If you've set it up correctly and FX still don't work, unless you want to keep using it as-is, I'd suggest looking for a used replacement on Ebay etc. They sell for under $70, and although I doubt these can be repaired, it wouldn't be worth it anyway.
I couldn't find any tech data for 35/55/65, but it looks to be similar to a large Yamaha I had to repair a couple of months ago for this same issue.
Keyboards can be practically difficult to work in, and can have very fragile interconnects. I wouldn't recommend anyone unfamiliar with working with electronic equipment and the risks involved to attempt this repair.
It may well respond to careful cleaning of the rubberized contact strip that sits under, and is actuated by, the keys. The pcb pads underneath that act as contacts should be cleaned too. It's a good idea to remove any loose dust and debris with a vacuum and a soft brush before lifting the contact strip out, this reduces the likelyhood of introducing problems on other keys. I then used some isopropyl alcohol and a cotton bud on the underside of the strip and the pcb pads. Very little pressure should be used in this process, as extremely fine layers of gold are involved, it's vital for reliable contact. I prefer not to clean areas for keys which were not affected.
There may be an additional issue, if the coke really was the cause then there may also have been acid corrosion of pcb track over the years. This should be repairable though. Inspection with an illuminated magnifier is recommended, or a cheap USB microscope will do a good job too.
Personally, I would say that this really is a job for someone qualified and experienced.
This can have to do with several things. You might have a lot of sounds installed and have a lot of projects that you are working on. You can also have a small memory that is not improving the boot. You can expand your mpc memory, take a look at the link for an example:
Read the manual. I think you'll find that you've recorded them as sound bytes instead of full recordings. If that don't work get in touch with Akai.com. You paid good money for the machine and YOU ARE THE CUSTOMER.
Good Luck
The procedure is as follows: go to the INIT Screen. Hold down SHIFT and press OTHER (8 on the numeric pad) to display the OTHER mode screen and press INIT [F2] to display the INIT screen. This will initialize ALL PARAMETERS.
Pressing DO IT will initialize. Pressing DO IT [F6] erases the parameter data from the MPC2000XL memory and initializes them to their default parameters.

Hope this helps. Take care, and thanks for using FixYa!
Please try to reset the ewi. You can do this like this: Shut down ewi. Press down the four little white buttons Level, FX, Setup and Trans. Keep them pressed while starting up the ewi.
This is a factory reset.
