Has anyone got a copy of MPC 3000 Service Manual!!!!

My samples always seem to have a pop or click on the end of them, so i think my output stage needs recalibrating.

Cant do this without service manul if anyone could help or shine some light on how i cn get a copy i would be most thankful, thanks in advance, Karl...

Don't assume recent posts about the MPC60 and its output stages are in anyway associated with a problem your MPC3000 is experiencing.

The MPC3000 does not have user circuit board located adjustable/trimmable output stages.

The MPC60 output stages are WAY different to those of an MPC3000.

Click on the ends of your samples are more likely caused by faulty/incorrect/failing sample RAM ( or in some rare, rare, rare cases ; failure of the SIMM RAM controller PLD )

If a sample taken on your MPC3000 crackles/clicks/pops when played back the sample RAM is most probably the culprit.

How is the RAM configured in your machine ?

What type of SIMM chips ?

Original AKAI EXM memory board present ?

How much RAM is present ?

Not sure about the above questions ? Then post a picture for all to see.

Hello Rohan

My MPC 3000 LE, has 2x16meg sticks of ram bought from here:

http://www.memoryx.net/mpc3000.html

They have been in my machine about a year the guy at synth repair centre (In London) took out the standard Akai EXM ram board and other ram that was in there.

I think it was either a 8meg Akai board and 2x1megs sticks or 2meg Akai Board and 2x4meg sticks as i originally had 10megs worth of memory when i bought it, so now i have 32 megs of ram.

I followed all instructions from: http://www.mpc3000.com/

So you think it could be my Ram then???

It's really weird when i sample on MPC then store my samples i've taken on my HD, go back to it at a later date and try to make a program with MPCPGMMAKER, the samples clip as they sound just that little bit longer than how i chopped them.

If i chop up stuff in recycle when i finally get it into MPC it takes about 2ms off of the end of the sample length really weird!!!!.

Sorry for jumping the gun as in regards to other post but i thought maybe that was the answer to my problems, if there is any more info you please let me know

yeah, one of the mpc quirks..

Good RAM, used it my machine once then upgraded another with it before buying more at a later date.

Ok ... so all is "right" in the RAM department.

With the additional information you have posted below I think there might be a process problem with your procedure.

First lets look at some thing simple.

Take a sample on your MPC3000.

Play it back on your MPC3000.

Does it crackle/click/pop ?

If not. Save it to a fresh MPC3000 formatted disk.

Power down, power up, re-load this sample.

Does it crackle/click/pop ?

If all is good with the above steps then the MPC3000 is performing fine and you can assume the RAM to be OK.

OK ...

Sorry ... the "samples clip as they sound just that little bit longer than how i chopped them"

Clip ? or Overlap ?

If you chopped the SNDS in your MPC3000 then you would have needed to "replace same SNDS on disk" when you went to save them.

That way your newly edited SND files would replace any existing ones on disk.

Another issue to consider:

Problems can happen with COMPUTER<>MPC3000 data transfer where you use the same disk for working in each environment. ( Long and complicated reasons why )

A point to note here is:

"Use an exclusive disk for each process of the data transfer".

Use a seperate "mpc3000 only" disk for your MPC3000.

Use a seperate "transfer" disk for the data transfer between COMPUTER<>MPC3000.

Save from the COMPUTER onto your "transfer" disk.

Load from the "transfer" disk into your MPC3000.

Once the files are loaded into your MPC3000, save from your MPC3000 onto the "mpc3000 only" disk.

I think you mean 20ms not 2ms.

From the manual:

"COMMENT: Because of the way the MPC3000 internally
plays sounds, up to approximately 20 milliseconds (randomly)
of the end of a sound is not heard. Take this into
account when playing a portion of a sound. For example,
when playing a region from 001.000.00 to 002.000.00, you
may only hear all but the last 20 milliseconds of this region."

In reality this random ammount can be "up to 20 milliseconds".

The solution is to add some dead space to the end of your sample.

...... and program your envelope decay accordingly.

I hope the above is enough to help you get back on track.

Rohan.

Thanks Rohan

Today is the day 'll start using my transfer disk if i have any probs will let you know.

Also on your point about chopping the sample, i usually just load the original SND from the zip disk.

Then rename it when its in MPC memory, chop it how i need it, then save back onto zip disk with new name then reload original sample again (if i need to take another chop off of smae sample) and repeat, hopefully this is the right way???

I hope this process works for you as it has for many others.

Sounds good so far.

It makes the most sense and should not be causing any problems.

Rohan.

jesus i could never work like that

How do you work C.Toon????

asking as it sounds like you gotta quicker way to chop!!!

well my way doesnt include saving each sound before chopping, I just leave it in the mem, untill I reach the point where I'm sure enough to delete the main loop/phrase. I just copy the sound a few times, change the start and end points and build up the track. Once I feel the loop is tight I can just discard the main sample I copied from or even save it if i wanted to. Then I just get rid of the slack before the start and end points of my samples and youll have more space to add other sounds. I'm pretty sure I will change my technique very very soon because ...*drumroll* I finally ordered a PCD25 .

I guess now I'll just sample huge chunks into the 3k, save em to CFlash, chop in the PC save the main loop there and put the chops back onto the CF so I can load them back into the MP. I know there will be some loops I will prefer chopping in the mp without staring at a waveform esp, since you can tweak the start and end points while sequencing and therefore get a better timing/flow of chops laid down. You would have to leave some space on the start and end point if you were doing the entire CFlash >PC >CFlash thing and dont want to loose the flexibility.

Hopefully, soon enough Rohan will implement a better way of chopping than copying and renaming sounds all the time, but you gotta give the man some time

.toon

I hear what your saying Toon maybe one day Rohan will sort it. Most of the time i like to chop my stuff up in the MP it's just when i do it in MP my sh** is real focused.

I dont miss a beat got all kinds of audio editors but some days i like just like to keep the comp off just me and MP total silence

Bliss!!!!!
