Re: state-of-the-art multi-instrumental/transposing mechanism

[Jan-Peter Voigt]

Hi again,

it needs some more thinking, how key signatures can be treated right for 
this case. It is all about the timing - if you set the 
instrumentTransposition with the editionEngraver, the properties are set 
early and the keys look fine here.
I am going to add key-sigs to the EE, so that they can be added as 
editionMods.

Best
