I turn on MPC2500. It won't boot up. Screen says" MPC2500 128 Megs insalled" and screen blinks. I hit window button so 2500 OS update screen pops up and prompt says wrong card. This all happened after I updated sofware, Turned the machine off and then turned it back on. No boot up. Already tried holding erase button while powering up. Cannot reload software. Same screen comes up. What should I do to reload software?

Hello there,
You dont say what was wrong when you said it was being 'fixed' and a Hard Drive and/ or CD added.
Has it been updated to V1.24 software which fixes a bug in hard drives formatting ? As per the release notes. http://www.akaipro.com/product/mpc2500#downloads


I would very much doubt there is problem with the IDE interface UNLESS this was the original reason you were having it fixed.

I would take it to the AUTHORISED AKAI PRO Dealer to have it inspected.and a PROPER understandable report given to you if the Machine still won't accept a Hard Drive or a CD mechanism.
Go to bottom of page here For AKAI PRO dealer near you. It cannot hurt to get a second opinion.

hello I have the same problem, I'm told that updating the firmware of the Lexicon MX200 is solved but it turns out that my pc does not recognize the device via USB to update, any solution? thank you very much

from the akai forums:


to set the os back to factory settings press and hold the erase key till the mpc has booted to the main screen.

to erase the harddisk goto either the load or save screen and then choose utility - there you will find the option to format the hdd.

you can also format the drive (or any inserted compact flash-card) from your computer thru the usb connection, but it is recommended to use the internal format because the mpc can be a little picky when you format it from the outside.

at first i would check if there is any folder or the internal memory is set to autoload and just turn that of or point it to another folder of you choice. that way you can keep the factory delivered sounds. maybe you want to use them later, even if it is just to explore the mpc. the factory sounds can be also downloaded later, but be advised that there are different iterations of the stock sounds, depending on whether your mpc shiped with a 32 or 128mb compact flash card.

also the mpc os is not on the harddrive but in the internal memory. to check the version hit mode-> pad10. latest official version is os 1.24. if your main srceen looks different than in the manual check double and triple before you do anything, because the previous owner might have installed the third party jj os which comes in different versions. some of them cost a lot of money! if you find this check the other forum here for the alternative os.

If the shaft/actuator snapped off a part on the board, then you will have to do unsoldering and soldering. Removing solder from the boards without the proper tools may damage the circuit board.

If you flashed a bad OS, the unit MAY have to go to the factory to be reloaded.

Go to VSPlanet.com and see if someone there might be able to help.

Try holding erase while you turn it on. You may have to turn off autoload also. You'll have to read the manual first ( pages 110 and 114 especially ) available here:http://www.mpcsounds.com/download_akai_mpc_manual.php It depends I think on whether the previous user saved to memory card or the internal HD.

To get stereo you must record in stereo or "PAN" individual inputs to one side or the other to create seperation. Your device is NOT broke.

Read your manual about panning.
