Exchange tips and tricks for the Akai MPC4000

the effects card is not integrated.

it is like the 8-out card, a separate unit.


it could be bad ram.
try remove the ram, and testing each ram stick individually.

also while the case is open, make sure the effects card is seated properly.


I don't know what else to say for now.

try the ram test and get back to us.

I tried just that. i removed both ram sticks and ran on the 16mb that comes with the unit. Delays still distorted!

Do u have instructions for removing the effectscard?

I really cant find it inside the mpc, is it located under the cpu-board?

Thanks for your help.

However it turned out to be a broken effectscard. Got it of ebay, plugged it in, now it works fine.
