I think we’re saying the same thing. My hypothetical \takeInstrument syntatic 
sugar would put the desired markup, \set the autoTransposition, and a number of 
other things, as set in some \addInstrument (or other) definition.

Agreed. I’ve been offering to sponsor this for nearly a decade — hopefully it 
happens soon!

Thanks,
