It depends what the root note of your Aeolian is.
Assuming C Aeolian, E will become Eb.
When a note is not in the scale, FTS looks to see if the note 1 semitone
below is.
If that note is not in scale, it looks 1 semitone above.
It repeats this pattern, 2 below, 2 above, 3 below, 3 above, and so on until
it hits a note that is in the scale.

Internally, this isn't what happens in realtime...
There is a map table for each note in the chromatic scale, indicating which
note it should map to.
This map is calculated using the process desribed above whenever a new scale
is selected, or the current scale edited.
The practical upshot of which is that if I decide to provide direct access
to the map table, you could have an FTS scale that maps one note to another
'distant' note, where there may be other notes in between.
But that's for another day...

Assign aux A to 'rndmz aux C' with a value of 1. That should do it.

You could push the alternative values for the rel notes from another track,
and then use muting of that track to control which values are actually used.
