chart-editor's Issues

Implement transposition with enharmonics

Currently, the transposition does not take into account enharmonics (coming from the fact that a note can have multiple names, like C# and Db.

The implementation might be pure or practical (eliminating the odd chord names).

While transposing the chart key doesn't change

During the elm-europe demo I realised the key of the chord stay the previous note rather than the transposed one.
