The keys are very hard...

Hi , many keys are very hard on my MPC3K , i changed several parts , ( soft key keys , cursor keys...etc ) but the problem is the same...
I opened the MPC and made a cleaning , but the problem is the same...
I think it can be the " pushbuttons " who are under the keys , and who are welded on the board...
Is anyone who know this problem can help me ?
Thanks.

Do not spam him but mpc3000le would be the one to know along with others but he is the one I know off top.

You just need some new switches. Try mouser.com search for tactile switches. The MPC60 uses PN 688 SKHHAM, they're probably the same for the 3000 too but you should double check that.

3K pads are very hard. If you press down in the middle of a pad it barely moves, its only the corners and sides that move. But don't take that lack of movement meaning that you have to hit the pads harder...

Thanks , for the link
Do you know how can i check the " tactile switches " model for the MPC3K , i'm beginner in electronic...
Is it possible to know size , force and travel of the Akai Mpc3000 original switches ?
Have you measured ?
How have you find the good model for your Mpc60 ?
For pads , i replace them last month with new Akai parts ( same as the Mpc2000 ) and they work perfect now...

Here is hoping you can do the removal/replace routine in a clean fashion.

Maybe invest in a "de-soldering station" which will make the job a LOT easier to do. ( they are cheap and a good investment for future repair work ).

As for your MPC ... A new backlight, OS 3.16 in ROM's and new tactile switches on the way...

Now THAT is what I call re-furbished.

I agree, having a desoldering kit is a must!
It's alot safer on your components, as well as making the job much easier....
but caution still needs to be taken, not to overheat and damage the board.
also, making sure that any remaining solder thats barely visible around the area is cleaned up with some isopropyl alcohol and cotton swabs to insure nothing shorts out.
