Man finaly some kind of Success!!
Now that I´m proud Owner of a Second MPC 60 (Besides a 3K and a 2500) :-D
I could read out its OP Rom and the Outcome was that the First **** Byte was different (4E instead of 0E).
So the Dump i posted seems to be faulty in the first Byte, rest is ok.

Further I tested the Rom from the faulty Machine in the working one with the Result:
The Working Machine boots but has no reaction --> Error seems to come from Rom Chip.
Also bought a new Rom Chip off Ebay and so i will see if it works with a newly burned OP Rom Chip...

Now as a next Step I need OS 3,10 instead of 2.04 because saving sequences all the Time before sampling sucks :smoker:
Somebody can help me out with that in some way?

Very old thread... But an unresolved one.

Long story short:
Just finished rebuilding an Mpc 60 that on first tests worried me that it had this ghost issue.
Luckily... It was a multi setting that I had overlooked lol.

Anyway, this had me thinking about why this fault happens and what could be the cause.

After looking at the schematics and a little head work I am sure I can cure the infamous ghost fault.

Any one in the uk have a machine with this error?

Obviously the fault is a bad one so its likely that someone has a machine in a box gathering dust that could be revived.

I am not after £, I am looking to solve this fault.
No fee to pay, even if repair is successful.

Just a heads up. If you have the "ghost in the mpc" problem or crakling in samples.

It's a good chance it's bad Ram.

I know this because I just took my Mpc to Forat with the same problem and I watched him troubleshoot.

My Mpc had that daisy chain hack ram extension mod from 1993.

What he did was sample 5 sec of music on each pad until he used all the memory.

We noticed the crackling on the 4th or 5th pad, that signified a bad chip in the 2nd half (whatever that means, that's what he said).

Told me that he could remove all of the old soldered in Ram and put in new ram for 100 bucks. I'd be loosing that hack ram extension, but I could just get grab memory later on.

I agreed and it worked! No crackling.

Hope this helps someone down the line!

I have also seen a ram hack cause ghosting and I removed the lot and replaced it, this did solve the problem. It is not the answer in all cases though as many previous posts will tell you. There are a few other things other than the ram chips themselves, but all are very repairable

another reviving the old thread.

I think my mpc 60 is having this ghost issue and crackling noise on longer sample.
So is it confirmed that this is ram expansion board issue?
how can I know whether my mpc 60 has the memory hack instead of the expansion board?

^ the cracking in sample trigger is getting bad for my 60 as well. generally it is at the start of the sample in my case.

double checking to see if a ram replacement will fix this one as well?

I am also having the static issue on my MPC60 II. Replaced the expansion RAM and that did NOT fix the issue. Just chiming in to keep this thread alive.
