Hi,

I bought a used MPC2500 with JJ OS 1 on it. I'm kind of new to the JJ OS.

Should I upgrade it to JJ OS3, or to XL? Or should I just leave it like it is?

I just updated last week and I think it's great. New features in the grid edit and program edit.

You can just try it. If you don't like it, just return to xl. 8)

Thanks for your reply.
I have JJOS 1 (v 5.56) now. That is not XL.

So how do I upgrade to JJOS 3?
The info on the website is very brief, and I'm a newbie to the MPC world. A little help would be appreciated.

You can buy XL on the JJOS site using paypall. They'll send you a code you have to enter in order to save your projects.

JJOSXL can be freely installled to test out. Only saving is not an option unless you have the code.

Upgrading from XL to 3 is free.

But all this info is on his site also.

Good luck.

is OP asking how to pay or how to install?
tacozip you first have to update the free JJOS before any upgrades can be done. It is an intrinsic part of the other OS s and it says so on the website. Then you will be able to load the the other OS like XL or OS3 from the load screen in Free JJOS. I use OS3 and some here might say its not worth it cos they are happy with OS1 or what ever as it does what they want. But for me there is too much to list to make it worth while for me

I have one more question:
I'm using program mode a lot. The comparison chart tells me "old program mode" has been removed in the newer versions (I run JJOS v1).
What can I expect of the new program mode? Is there stuff that I won't be able to do anymore after upgrading? What are the big differences?

I tried JJOS3 but now Im back to XL because 3 doesn't have the grid edit midi piano roll edit features XL has.

When this gets implemented in 3 I'll go to 3.

Hi tacozip,

There are many changes (gains and losses). Hard to describe everything in deep but here is a quick summary :

First of all program mode is mode + pad 04. Mode + pad 07 is looper mode now.

Regarding drum program :

Different tab order, different layout.
The note order is different. Please read this : http://www7a.biglobe.ne.jp/~mpc1000/os2xl/important.htm

You have non destructive mono/ stereo/ L+R / forward/ reverse settings. There is a chop field linked to NDC in TRIM MODE.

You have a level column. Very handy for pre-pre-premixing. There's another level column in the OUT tab which is affected by the mixer (Qlink and so on)

If you press WinDOW over the pad field you get there :

It's the layer screen. You lose one layer (number 4).
The behavior of the WHOLE button is different.
You gain aftertouch Xfade and CopyPad. (you can copy a pad or a setting with the UNDO button shortcut by the way).

Image
Image


F2 tab. In OS2XL you have ADSR (AHDSR in OS3)
The velo collumn is very useful if you want to "compress" your velocity.
LOOP&HOLD added to play mode

Image
Image


F3. In os2xl LFO is shared with mute (you need to press the button one time or two times)
So it's FILTER now. You gain envelope, depth and aftertouch principally. Filter2 settings are more limited. You gain EQH and EQL for mpc1K.


Image
Image


F4. It's PITCH in os2xl if you wanna mess with pitch settings (env, depth,aftertouch)

Image
Image
Image


F5 for LFOMUTE. Regarding LFO you lose filter2 but you gain aftertouch (it works with pitch). Concerning MUTE you gain CYCLE.

Image
Image

F6 is WHOLE in os1 and OUT shared with FX in os2xl.

Different layout. Addition of a Track mixer.


It would take hours to do a comprehensive comparison thread so just try and have a look by yourself :)

There's a new type of program , INST program too.

Check the online manuals :
http://www7a.biglobe.ne.jp/~mpc1000/manual_e.htm
http://www7a.biglobe.ne.jp/~mpc1000/os2xl/manual_3e.htm

To conclude I'd say that OS1 and OS2xl are like night and day. You lose 10% but gain 90% if you do the balance with all the features in the other modes.

Wow. Thanks a lot for the detailed post.
This is what i've been looking for.

Seems like a lot of pros for the newer OS. I will definitely check it out.

Thanks again!

You're welcome :)
My bad I wanted to say pad 07 and pad 11. Can't edit the other post anymore.
You can check OS3 too. Some features added, some removed. Non destructive slice in program mode for instance. It could fit your needs too.
