So after about 4 years I've stated making beats again, teaching myself the mpc again. So when I left off I seem to have jj os 4.94 and I would like the newest version to learn, is it 2xl or 3? Also, I don't really have a computer but I have smartphones and a surface. So what's the easiest way to get the new os? My mpc has a hardrive and the ram upgrade. Can I save it on my phone and transfer it over with usb?

If you have microUSB or some other way to get the operating system file onto the CF card/HD of the MPC you're good. One example if you don't have the right cable is using a CF to USB adapter or something similar.

Basically over the past several years the two most popular JJOS versions are OS2XL (1000)/OS-XL (2500) & OS3. When you go to the JJOS site and see 128XL & 128SP these are versions of OS3 & OS2XL/OS-XL ported for the XLCD screen.

For a while OS3 was thought to be incomplete and buggy but those issues have been sorted out and it appears OS3 is finalized. OS2XL/OS-XL is also finalized, meaning no new features will be added other than bug fixes, so check the comparison charts to see which features are in OS3 that aren't in OS2XL/OS-XL and vice versa.

OS2XL/OS-XL has for the long-term seemed to be the most popular option, but part of this might have to do with a combination of OS3 being newer (more bugs as it was being developed and gradual adaption of new features and old features from OS2XL/OS-XL) and because of this many users developed personal workflow habits on OS2XL/OS-XL that made switching over a bit harder.

Looking at the most recent versions of both, they're actually really similar with minor discrepancies in menu navigation. Most of the features that originally were not in OS3 that OS2XL/OS-XL users couldn't live without (non-destructive chopping for example) found their way back into OS3.

The two most recent videos uploaded on the JJOS demo YouTube channel show both operating systems in XLCD form but these roughly translate into small-screen as well (minus mixer in the MAIN screen & more vertical space in grid editing, etc.)

Other info to be more exact:

OS2XL/OS-XL *might* still be taking development requests other than bug fixes but according to the comment on the video, "Moreover, there is no plan to add a function to OS3."

There still might be some development on the XLCD versions but I really have no clue.

Also, OS3 was originally the small-screen version of 128XL.

However both operating systems feel more or less complete. Either one is dope in my opinion. I've been stuck on OS2XL/OS-XL, spent a year using OS3, went back to OS2XL/OS-XL but now I might go back to OS3..

Thanks so much guys! I'm now running on os3! I'm learning out as we speak and got a Mic to record vocals with. My fiance can sing good.. For some reason my jog wheel acts really jonky on 2xl or 3 but is totally fine on os1 5.00, any ideas why that would be? Over all I'm really glad to have the newest one and I love how you can c&p whole tracks to different sequences. That changes things quite a bit for me.

You have to change the data wheel type.

JJOS Manual wrote:When the reaction of a DATA wheel is slow or cannot change the value of one step, please change the set of the "Data Wheel Type" field of OTHER.
Usually, MPC in which Ver2.12 or less AKAI OS was installed selects 1.
MPC in which Ver2.13 was installed selects 2.
If OS is changed, this set will return to default setting"2".
