What is JJOSXL?

JJOS 'XL' is an advanced third party operating system for the MPC1000 and MPC2500 created by the developer who worked on the original Akai OS for the MPC1000/2500. The OS can be purchased from the JJ web site - you'll get a code to enter in your MPC and the software becomes fully functional.

The actual name of the software differs depending on the MPC model you own. The MPC1000 version is called JJOS2XL, the MPC2500 version is called JJOS-XL. However the software is essentially identical for both MPCs and for simplicity we refer to both versions as JJOSXL.

Is this book suitable for JJOS 128/128XL (the JJOS for XLCD large screens from

No, this book was written for the 'standard screen' JJOSXL (i.e. JJOS2XL or JJOS-XL). You can of course run the standard JJOSXL on the XLCD large screens, however only half the screen would be used by the OS in this instance.

How do I check what OS I'm running?

Go to the OTHER screen (MODE and pad 10). In the top left of the screen your OS will be listed. It should read something like:

JJOS2XL Ver.:3.26


JJOS-XL Ver: 3.26

Will this book work with other versions of JJOS?

This book has been written specifically for JJOSXL 3.2x (3.26 was the current version at the time of publication) - if you run an older version of JJOSXL, there may be some features discussed in the tutorials that are not available in these older versions of OSXL. We advise you update your current install of JJOSXL with the latest version from JJ's web site.

If you run a completely different JJOS (e.g. JJOS2, JJOS1, JJOS free, or JJOS128XL), then there will be significant differences, so we cannot officially recommend this book for you, but do let us know if you would like to see a version made for your OS.

What Is An Ebook?

An ebook is an electronic book that you can read on your computer (or on a PDA, mobile phone, ebook reader, etc). Our ebooks also include folders of example files that allow you to recreate the tutorials as you read them. Our ebooks can be downloaded instantly after purchase and can be opened using any free PDF reader, such as Adobe Acrobat Reader software (most PCs already have this installed), or the built in 'Preview' PDF reader found in all Macs, iPhones and iPads.

Can I make backup copies of my ebook?

Yes, once downloaded it's just like any other computer file and can be copied to a back up disk.
