I tried to update my O.S from the demo to JJos.xl.As it was loading we had a power outage.Turned it back on and tried to re-install it.Thats when the problems started.How can I install the JJ-OS, if my CF Card Reader is not working? And my pad functions are not working too.So, there's noway to load anything because my pads seem to be shoot.Everything else works

Hey,no pad functions are working.Like if I pressed [Mode] + Pad2=load.. nothing happens.Windows button works.....I tried the reset thing but no luck...you know when you turn on the mpc while holding the windows or the erase button..

what os is currently on your mpc?

try to reinstall the akai os or early jj os using the procedure described in their manual (ie, holding a button down with the bin file in the root of your flash card while booting up)

you shouldn't need the pads for this, only the buttons, which you said are working

Try that with akai OS :

====How to update the MPC1000====
MPC1000 is updated using a Compact Flash card containing OS data.
Insert a CF containing OS data into the MPC1000.
Turn on the power of the MPC1000 while pressing down the “Window ” button.
To start the update process, p ress the “REC” button. After the update process is finished the MPC1000 will re - boot automatically.
Note: The MPC1000 can not be updated from a computer via USB directly – updating is only possible using a CF card.


If that doesn't work you may have a Fuse blown inside your MPC.

in my experience with the mpc1000 and fuses, if the fuse is blown the thing won't even turn on
was your CF card broken before this incident?
if you think it's broken after the power outage, how do you know it's broken (since you can't access it without mode/pad 2 or 3?)

I'm sorry we lost power in my house!When the power in my house came back on... That's when I tried to re-install the o.s..Everything works except pads and cf card reader.So its impossible to do anything!....thanks for the reply!

If you can access the CF card then I'd say a smart thing to do is to activate USB mode and check the CF card with some test programs. I don't know what system you're on, but in Windows you got some disk tools accessible under the tools tab in the properties. You right click to get access to the property window. I'd start with a backup then defragment the memory card. As stated above I don't know Mac, but this is the only way I know.

@Nym: I really enjoyed your beat in your signature.
