Hi Jean,I totally agree that the \instrumentSwitch and \addInstrumentDefinition functions are useless. Just use variables. (Contrary to what its name suggests, \instrumentSwitch isn't directly related to Instrument_switch_engraver.)Please take a look at https://github.com/openlilylib/snippets/tree/master/editorial-tools/auto-transpose and how \addInstrumentDefinition is incorporated there. Would you say variables are still better in that use case?
Yes. Don't you find
ebClarinet = \displayMusic {
\clef "treble"
\transposition ees
\set Staff.shortInstrumentName = "Es-Kl"
\set Staff.midiInstrument = "clarinet"
\set Staff.instrumentCueName = "Es-Kl"
}
easier to write and read than
\addInstrumentDefinition #"eb-clarinet"
#`((instrumentTransposition . ,(ly:make-pitch 0 2 -1/2))
(shortInstrumentName . "Es-Kl")
(clefGlyph . "clefs.G")
(middleCPosition . -6)
(clefPosition . -2)
(instrumentCueName . "Es-Kl")
(midiInstrument . "clarinet"))
?
You can *always* convert any use of \addInstrumentDefinition
/ \instrumentSwitch by turning
\addInstrumentDefinition "x" #`((prop1 . val1) (prop2 . ,val2) ...)
\instrumentSwitch "x"
into
x = {
\set Staff.prop1 = #'val1
\set Staff.prop2 = #val2
...
}
but with the latter syntax, you can also use any command
and not just \set Staff. ...
