Great advice, and speedy, thanks, Marc! But my inspection so far has not lead to any revelations.
My goal: change transposition on one staff without changing instrument
Why I want this:
19th century brass parts often switch keys, so quickly that it’s obvious even the original players were not switching instruments or crooks, but only reading different transpositions on the same horn (the way all players do today). I want to take for example a B♭ Trumpet, say simply “in F” right before an entrance and later switch back to B♭ and have it play back correctly. What Sibelius calls an “instrument change” object does this job (and handles the key signature, if any).
There’s no need for a separate staff cluttering up Galley View because it isn’t a real change of instrument, and also I don’t want to say “To F Trumpet” at the end of the previous passage. I know this has been requested several times, and I have read those threads carefully. I have looked at “Clef and Transposition Overrides” and that is not what I’m after. This is not at the level of flows or layouts, but within a flow, in all layouts.
I have made:
- a Playing Technique that is waiting for an EM assignment
- an Expression Map called “up 5th” with Base: Natural transposing up 7 semitones (on the model of EM “Transpose up 1 octave”)
- another EM to undo the transposition (is this the wrong approach?)
- a new playback technique which I have assigned to my Playing Technique, but which doesn’t do anything
I still cannot see how to connect an EM to a Playback Technique. Maybe I’m going about it wrong. But I have seen mentions on here of temporarily transposing playback by other than an octave, and I have wondered for a month now how it can be done. Thanks for any insight.
