It shuffles whatever you have the 8thspercycle set at. I've only used 4 and 8 but I can imagine you can probably use any number. So in MOS, it would be:
Set 8thspercyle 8
Shuffle
Or if want to try /u or /r after 'Shuffle', you can.
You can also be specific with how you want them shuffled.
You can say
set 8thspercyle 8
Shuffle subcycles 8,7,4,3,2,1,5,6
I figured all this out from other people's scripts. Was fortunate to start using Mobius when they were still available but here, let upload them to my google drive and you can download them.
