Yep. I think he does too 😉
I realise this is MainStage, but Tunings (Temperaments) are dealt with in the Logic Pro manual (p.948):

+Each semitone can be detuned (moved away) from equal temperament in semitone steps. To do so, just click-drag—vertically—on each semitone box until the desired value is reached.+
The reason alternative tunings are mentioned in the Logic Pro manual (in the "Project Settings" section), and not in the Mainstage manual, is that they only apply to Logic projects. Mainstage does not directly support altered tunings.
The 'Persian Santoor' setting referred to by the previous poster is a Garageband 'Strings' instrument setting. This can be opened in the EXS24, both in Mainstage and Logic.
It may have been possible to alter the tuning of the individual samples within the EXS editor, but in this particular case, the samples are mapped across several semitones. I suspect that your need to alter the tunings may not be possible with this patch (without a lot of work).
Note that, although there is a button on the EXS interface, the EXS Instrument Editor cannot be opened within Mainstage; only in Logic.
