upgrading from jjos 3.16

Ive had an mpc the last few months trying to get my head around the 1000. I am now looking to upgrade the OS so i can have chromatic scale using my midi keyboard and a single sample and also the use of the ADSR.

However, I am a bit confused about which one to go for? I checked out the comparasion chart, but alas still unsure. Is JJOS2XL the one that has both the chromatic scale and ADSR envelope?

yes it has all bells and wistles, even older os 2 got it, but I see it's no longer option to buy separate. So... only one option now: ONE license for all Systems and you can decide which one do you prefer with hands on.
