Thanks for the explanations and the pictures :)
If something else comes to your mind don't hesitate to share.

What are the pros and cons if you compare the LOOP function?

I saw in the manual that there are more settings for LOOP in the MPC4000 but I didn't figure out if it's possible to have a sample loop&holding on the fly in Main screen. What is called hold corresponds to note on in newer MPCs no?

You can toggle the sample so that it loops without holding the pad, but by default a loop would be triggered as a note on or 'as played' sample as it's termed in the 4K. *I'm not sure why they stashed the toggle option away in the pitch edit screen, but it's easy to find once you know where it is.

Another advantage of toggling a loop is that your pads are still active in load. You can't simultaneously trigger a pad and audition a sample at the exact same time, but there is some overlap. A toggled sample will continue to loop as you audition sounds, which is a useful function to have.

You'd have to cross reference the various loop options in JJOS to the 4K. It's been too long since I had my 2500 to remember all the details, but there was nothing that I missed when I made the switch. :)


Edit: I just realised that you can select toggle from any of the edit screens by selecting the note number and pressing open window. Oooops. :oops:

Another little bonus you may not be aware of is that you can plug a wireless dongle into the front of the machine to use a qwerty keyboard. You can also navigate most of the machine with one. :smoker:

One thing I like about the 4000 is having multiple options for peripheral file storage devices. The fact it supports, SCSI, USB host, and USB slave is amazing. No other MPC is this flexible. Also, I like the fact when you use the MPC4000 with Aksys, the computer not only sees what's on the MPC's harddrive or connected drives, but also everything in the machine's memory. No other MPC does that either. When you add the ability to connect other types of peripheral USB devices (computer keyboards, etc..), the advance sampler engine, large memory capacity, and other advance hardware I/O options, and a very flexible and fully featured OS, the MPC4000 is about the closest thing an MPC could be to a computer (the Ren doesn't count) without actually being one. I'd say the only thing the MPC4000 lacks is a VGA monitor output.

Now, as far as a JJOS 2500 or 1000 goes, it has a very nice and comprehensive workflow, which is what I like about it. It has all of the basic sampler features you would need. However, if you want a more advance full blown sampler engine, the 4000 can't be beat. Based on my experience with these 3 MPCs, one thing I must discuss here is program compatibility.

If you get a MPC1000 then get a MPC2500 and want to use the same sample programs, that's no problem at all as long as both machines have the same OS and OS version. However, be prepared to scratch your head if you're thinking about trying to use your JJOS MPC2500 or MPC1000 programs in a MPC4000 (the MPC4000 is not forward compatible). I'm not going to say it's impossible to do so. However, I will say it's a pain in the arse to attempt to do so because it is very time consuming. Furthermore, it would not be possible to do this without a computer and a third-party piece of sample program conversion software. Yes, that's right....you will need to convert your MPC2500 sample programs (using a computer program such as Awave Studio or Chickensystems Translator) to a format the MPC4000 will recognize, such as the S5000 or Z8 format. After you convert the sample programs and are able to load them into the MPC4000, you will then need to re-tweak several parameters with the program (envelopes, filters settings, etc....) as well as the samples (start and end points, etc...) to get the program to sound the same way it did in the MPC2500. I have successfully ported over some of my MPC2500 programs to my MPC4000 using this method. Although it took a while, I felt absolutely great after doing so and knowing I have a full sampler and all of the other advanced features of the 4000 available to my MPC2500 program, allowing me to perfect it beyond belief!!!!!

I've had my MPC4000 for a long time now. However, I've let it rest for a good while. During that rest period, I've been working in my other midi rig with the MPC1000, then later the MPC2500 not only for just making beats but also as sound design tools for perfecting my custom drum kits to my liking (which means finding good samples or creating my own samples from other sources, tweaking them with computer software, importing them into the MPC, then tweaking them further within the MPC using the MPC's trim edit and sampler engine facilities). By the way, I think everyone who owns an MPC should make their own custom drumkit. Once I get the drumkits slammin' in the MPC2500 and get them just the way I want them, I then port them to the 4000 and go to town. That way i'll have my "go to" sounds and programs in all 3 machines which are each used in different setups or applications.

I never considered using my MPC2500 or MPC1000 together with my MPC4000. Instead, each MPC has it's own MIDI rig. The MPC1000 is retired from a MIDI rig and was replaced by the MPC2500 as the brain sequencer of that rig. The MPC1000 is now mostly used for live gigs. While the MPC4000 is used in the other MIDI rig as the main sequencer for driving other MIDI drum machines/modules, it's also MTC slave synced to Nuendo 3 which is the main sequencer of the entire rig. While the Nuendo 3--Unitor 8--Amt 8 setup handles melodies from keyboards, synths, and sound modules, MPC4000 handles all of the drum-machine related sequences. This setup works beautifully and everything stays nice and tight timing wise. With this setup, I can also track vocals in Nuendo and everything stays in sync with the MIDI when it's all played back.

Oh yeah while I'm at it, I may as well say that if you're thinking about using your MPC1000/2500 sequences in your MPC4000, forget it!!!! unless you are willing to go through the trouble of exporting the sequence as a .mid file, importing it in the MPC4000 and re-tweaking the settings of all of the tracks to get the sequence to sound properly. I haven't tried this yet. However, I this is on my radar screen once I get a few more of my MPC2500 programs converted. With that said, I probably won't be converting sequence often because they won't sound the same in different MIDI rigs anyway. This might definitely come in handy for internal MPC program-only sequences though, or sequences in which I like the MPC drum beat but would rather use it with the synths from the MPC4000 rig.

Sorry for the long post but I can sit here all night and write about MPCs. In addition to them being nice machines, MPCs are also ADDICTIVE!!!! (like a drug perhaps ?) I've lost a lot of sleep because of them!!!!

Damn, now y'all have made me want an MPC4000! Anyone wanna trade one for a 2500? I've still got 2,5 yrs of warranty on it :)

Thanks for the trick with the keyboard Coz. I thought you still had a MPC with JJ OS so sorry for asking about specific details or direct comparison :wink:

Out of curiosity, is Aksys working fine for you? I heard that it was quite buggy. Do you think it will work correctly with windows 7 XP mode?

I never considered using my MPC2500 or MPC1000 together with my MPC4000.


This point of view seems to be shared by everyone.
For my needs I was wondering if it wouldn't be too time consuming or boring to trigger NDC programs or to launch MPC1K audiotracks from the MPC4000.
Other small things I like are non destructive features in JJ OS2XL programs like mono/L/R/stereo, forward and reverse.

Thanks for your long post kvmoore :)

I've started to save money for a MPC4000. I will probably cop a XLCD screen before if JJ put features that will give me a good reason to upgrade. I would be happy with improved audiotrack features like auto punch in/ out for instance :)

Aksys is working fine for me for the most part. It is a little buggy and it does crash every once in a while but not always. It's stable most of the time and it works well for transferring files back and forth between the PC and MPC4000 as well as editing programs. There was a time when it saved me from losing a beat when my MPC froze (this rarely happens) and I was able to save the MPC's memory contents to the PC via Aksys before shutting down and rebooting the 4000.

I'm running Aksys on an older PC using Windows XP. I haven't tried it in newer versions of Windows although I've read many people have been having problems trying to get it to work in Windows 7 and up.

I haven't tried that yet. Maybe I should just to see what would happen. However, I know the .wav files should load and play in the MPC2500 as long as they are 44.1k 16 bit. I'm not sure about MPC4000 programs and sequences though.

You know, that's not a bad idea. The non-destructive chopping is also one of the features I like about the JJ OS2XL as well. I don't think it would be too time consuming. All you would have to do is MIDI the MPC1000 to the MPC4000 and have the MPC1000 function as a MIDI sound module. Although I haven't tried this yet either, I don't think it would be too difficult to achieve.

Thanks for your long post kvmoore


You're welcome.

For those who are interested in the MPC4000 and have followed this topic, here is a
recent topic in the MPC4000 section that says it is possible to mount the 1K in the 4K :)

viewtopic.php?f=2&t=171558

I have a question regarding USB, CD or SCSI.

With the 1K it takes me approximately 15 or 30 seconds to LOAD/SAVE 100mb of data.

How much time can be expected when using a 4K (regardless of HDD)?
I guess it's USB 1 so pretty slow.

What about CD or SCSI?

CD is boring but I'm accustomed to it. I have an external SCSI CD burner I use with my DPS16 to get .wav files.

I also have an adaptec scsi card somewhere, waiting for a good occasion to build an external CF drive.

Has anyone already tried to use an external SCSI CF card reader with the MPC4K?

To sum up this question, is there something faster than USB and as easy to use as a CF card to exchange files with a MPC1K/MPC2K5 or a computer?

It's noticeably slower than the 2500, but it's not like going from a PS4 back to a Spectrum 48K and loading games from tapes! :)

The load times are entirely linked to the number of sounds you load up. For example, I loaded a few different folders containing various numbers of sounds…

102MB folder - 674 sounds - Time = 2.44
115MB folder - 100 sounds - Time = 1.29
114MB folder from CD - 1498 sounds - Time = 7.49

I'm guessing I've got a crappy 5400 RPM drive in mine, so those times may come down with an SSD or 7200 RPM drive.

I've heard that SCSI is the fastest way of transferring files with the 4K, but the front USB port and AKsys are the most convenient ways of bouncing files around IMO.

Thanks for your answer.

I always have less than 100 sounds in my folders. Glad to know that it shouldn't take so long then :)
