What are the Top 3 best features of JJOS?

I LOVE HAPPY ACCIDENTS...!

One minute you're like Ohhhhhhhh F*&K....! ... wait a minute hmmmm

A noob question here, if you want to install jjos xl, do you have to install jjos free ver then OS1 then OS2 then OSxl?

I'm asking as I'm getting a 1k soon and what to know about upgrade the OS.

Thanks

No just OS1

1. Alternate looping.
2. Loop edit mode. (ver. 2 only)
3. Grid editing.

Off the top of my head. I've said it before. JJ is what made me buy an Mp. Very happy with OS 2.

hmmmm... best features???? let me think............. ummm all of them! Buy the box, upgrade the pads, add the jjos and you will be painting happy little trees on an audio canvas near you in no time.
