Changing JJ OS version

Hi All,

I just bought an MPC1000 installed with JJ Os 3. The seller guy didn't give me any password or something to JJ software...

Is it possible to change to JJos 3 to XL for free, or i have to buy the new version?
(or i need the password...?)

If the paid version of OS3 is installed you can install every JJ OS without having to spend any money...

Thanks for the info!!!
Actually why i want to change is that the os3 has no tempo/timestretch function as i see...
So do you know what would be the next step? (because i bought with the installed jj os and i has no password, and don't know the method of it)

I have to ask the seller for password, account....download the xl version and install it???

just download XL and install. You don't need the password, it's stored permanently in your MPC's flash chip, nothing can remove this.

Wow....sounds good and easy!
Thank You!!!
