Yep, I meant this to be understood in my last post as I did write
that the background runs both up and down in pitch but also faster
and slower. And then on the second round this will be true for the
last added loop layer.
There is also another interesting aspect of this: You might as well
program the script so its UP vs Down rate shifting equals out to keep
the loop still in sync with other track's loops after the script has

No need to torture brain cells with hard-ass theory like that! ;-))
All you have to do is play along with live audio that sounds
musically good together with the new pitch of the background.

So true! This is why I love Mobius Rate Shift and Augustus Loop on Mac!

I've seen that in looping software and never liked it. Brrrr.... ;-/
