I would like to know if it is possible to change the tuning of A to say 432 or 415Hz. In the tuning systems dialog it seems the A is always fixed to 440, and there’s no way to change that. I’m interested in changing the tuning in the middle of a flow, the way Jacob Collier does, for instance.
The only workarounds that come into my mind are:
- Create a hidden accidental that shifts all the notes from A to G and put it in a key signature. Create new accidentals that are identical to the ones in use for A=440 in shape, but which include this shift in tuning. It could be created with a new tonality system to simplify things, although the inability to currently copy accidentals from one system to the other makes this process more tedious, especially if one has a lot of alterations in its tonality system!
- Create a different tuning system in which the divisions between A and B and between G and A reflect the change in tuning for all notes except A, and use a single hidden accidental for the note A. For instance, if I have a 1200 EDO system (cents) with A->200->B->100->C->200->E->100->F->200->G->200->A, and I want to shift everything down 20 cents, it would be A->180->B->100…F->200->G->220->A. That way, only the note A would be in 440. This reduces the amount of fake accidentals to just one note.
