2500 with some problems

Hey everyone I havent used my MPC in a couple of weeks I turned it on and found a couple things not working the way they should.

1. The jog wheel isnt working properly, you have to turn it repeatedly to change 1 value and is not easy to get what you want, I use the + and - buttons but still would like to use the jog wheel too.

2. one of my qlink sliders seems to function at first ok but then after playing with it, It jumps to random numbers like Ill put it all the way to the bottom where it should be
-120 and sometimes it will say -120 sometimes it says +95

3. When I am in sample assign window where you can change the tune from 00 to what ever if I leave the cursor there it goes to -36 randomly.

Does anyone know what would cause these 3 things to go wrong?
Im trying to figure out if it would be cheaper to repair my mpc or buy a new one?
I see on mpcstuff they have the qlink section for $40 and the jogwheel section for $95. I wouldnt mind these being the problem. I just hope its not the CPU which is $375.

Any advice, ways to test what the problem is?

Thanks

What O.S. are you using and what have you tried so far?I think you need to be more clear to get the help you are seeking.

At the very least it sounds like you have a bad Q link slider. You can get them from MPC stuff or cheaper on ebay if you know what your looking for. (I don't or I'd tell you.) I've had to replace one of mine on my 1000 and it's a good thing to learn how to do.
As for the jog wheel, I'm not sure. On the 1000 there are two different jog wheel options as Akai changed the encoders that they used. If you go to the OTHER menu there may be an option between jog wheel 1 and 2. If not, then you just need a new encoder. Mpc stuff may be out of them, but there's a place in Britian I believe called Rinaldis or something. (There's a link to the place on these forums if you look around a bit at the advertisements. Refresh the main page as many times as it takes to come up.
DO NOT just get a new Mp. This is really routine maintanance. If you learn to do these things, or find someone who can do them for you at a reasonable price you can run this sucker for a long time. Good luck

I am using JJ os xl 3.16 the newest os I tried the last couple os's and the problem was still there I formatted my compact flash card. I have the ram expansion but it's not the official akai issued ram I got it on eBay and seemed to work fine I installed it when I was using akai os so I don't know could be a ram problem. Anyone have any similar issues ever?

I checked the eu mpc site listed on the top of the page and the encoders are on back order. I am going to remove the ram later and see how the machine performs later. If that doesn't fix it I'm going to get the qlink replacement and the encoder if possible (anyone know where to get one?) I am thinking maybe I should do the Pad sensors while I'm in there as that could be my problem number 3. The numbers on my pitch only jump to -36 or -35.48 or some numbers like that, and that only happens when I leave the cursor on the pitch number then I hit every pad in order or out of order it just randomly changes the number is this some new feature I am misusing? Thanks

I think jumping values are a sign of dodgy/degrading Q-links.

I heard on one thread somewhere ages ago that somebody squirted Deoxit D5 into their Q-Links to get them to work properly again. That's worth a go because even if it doesn't work the Deoxit still comes in handy for the tact switches when they go, and jack sockets too. May even work on the encoder. But try this as a last resort- just in case.

If it does work though, then post that up in CAPITAL LETTERS with bells & whistles, because it will certainly come in handy for the rest of us.


I just cleaned my pad sensors recently. Some dust-mites or something were living on my sensors & then being squashed into the sensor. There was all this gunky white bug debris on the surfaces. I had some contact lubricant (servisol) which I dampened a tissue with & give them a wipe & now they're as good as new. But contact lubricant doesn't work on tacts & if you squirt that into your Q-links it may work, but they'll feel quite loose.

Don't know about the Pad Pitch thing, are they usually alterable with the q-links in your OS?

Good Luck

I got the deoxit D5 and the servisol, I sprayed the qlinks and the encoder wheel, and wiped the pad sensor. Now my jog wheel doesnt work all together. the q links pretty much swapped which one was faulty(its weird) so now the one that didnt work works fine and the one that did works worse than the one that didnt, the servisol did a good job cleaning the pad sensor though they feel brand new. which got rid of my problem 3. So now im going to order an encoder and a new qlink section. thanks for the help people.

^^^ Now that is weird. so it sort of works & sort of doesn't.

Thanks for trying that - Was worth a go if you were about to replace your Q-Links. I will certainly give it a try myself as a last resort, but its good to know not to do it if the Q-links are merely edgy rather than unuseable like yours were sounding.

Thanks for the research, I'm sure the team will certainly appreciate it. Good luck with getting your MPC sorted.

Here's the ref from mp3, who had more success with Deoxit in his q-links
