Temperaments and Pitches

Allowing the option to have different tuning temperaments would be such a useful feature to have, especially if one is trying to recreate or arrange pieces of a baroque style or when writing for harpsichord, for example Bach's Well Tempered Clavier. Even if there's only a few, such as Valloti, Kirnberger, Werkemeister or meantone besides just an equal temperament this is a feature I would love to see implemented.
Also, another good feature is having the option to hear the piece played at different pitches, like Baroque pitch or Viennese pitch. Solo pitch would also be particularly useful for when writing a concerto, for instance. Being able to set the solo instrument to solo pitch would be nice, to obtain the greater brilliance of sound. Having just a quick way of doing this is much easier than fiddling with the master tuning, or transposing the entire work down a semitone for Baroque pitch.
