SetUp + Scales

[XORadmin]

Exactly, "You can change the scale per track and if you want to have sometimes notes that shouldn't be in the scale then turn the scale off for that step and on again after that step." But how do I do that (switch it on for one or more steps, and then off again)?

To be more precise, if that's useful, I have a piece where much of the melody is using C major. Then later (same track), I have a section where I'm using C7 (Mixolydian). To be more precise, I have a section where I'm using RN1 (range) for the notes, so I'd like to make sure they pick only notes from the C7 scale.   

By the way, the 'SetUp' I'm talking about it the second line of the scale section: Global & SetUp.

I hope that makes more sense?

Thanks in advance.

The scale can be simply changed from the FX at any time for both global and tracks (CBPB) on any step.
The other one is also very simple:

Global is the current selected global scale.
With setup you can edit another scale which doesn't have to be the global selected one at this point. It is just to edit another scale without changing the currently global selected one.

So it is mostly flexibility without the danger that your current running sequence switches to another scale unwanted.
