6.18 MIDI messages (din help v7.1)

Creating MIDI messages in Sibelius
Because Sibelius reads almost all markings in your score and automatically turns them into appropriate MIDI messages when playing back (b 6.6 Interpretation of your score), you’ll generally only need to enter messages manually in Sibelius in very specific circumstances. These include changing the sound of a staff mid-way through a score, e.g. when, say, a clarinetist doubles on saxophone in the same piece, or if you need to use a different sound for different timbres on the same instrument, e.g. muted and unmuted. The clearest way to do this is to define a new word in the playback dictionary (b 6.8 Playback dictionary).

However, you can also tell Sibelius to send any MIDI message you like at any point, by typing it in as text using the simple MIDI message commands described below.

These MIDI messages can be appended to ordinary text and are hidden, so if you write 2nd time molto vibrato ~C1,90 in, say, a repeated section of your music, Sibelius will reset controller 1 (modulation) to zero to silence the staff at the exact point where 2nd time molto vibrato appears on the printout. ~C1,90 is automatically hidden (and will disappear completely if View > Invisibles > Hidden Objects is switched off – so it’s a good idea to switch this on before working with MIDI messages).

If you need to mute lots of staves, you can of course copy 2nd time molto vibrato ~C1,90 using Alt+click or z-click to save you retyping, or you can add it to the word menu obtained when you right-click (Windows) or Control-click (Mac), and assign it a board shortcut at the same time

– see Creating and modifying word menus on page 409.

When you import a MIDI file, you can choose to have MIDI messages in the file written into your score, in which case any control changes etc. will appear as if you’d typed them in yourself. Should I use the dictionary or MIDI messages? Most situations are more conveniently dealt with using the Play > Interpretation > Dictionary dialog. Only the most esoteric adjustments require MIDI messages, typically to exploit subtle behaviours of specific devices. Certainly if you want your score to play back acceptably on other devices, you should avoid using MIDI messages wherever possible.
Syntax
You can type MIDI messages into your score using any staff text style – typically Technique or Expression text. MIDI messages can be written on their own, or put at the end of any other text (such as “mute”).
Messages take the form: ~ followed by a single command letter, followed by one or more numbers, which are usually separated by commas.
E.g. ~C64,127
(~ is informally called a “swung dash” or “tilde,” but the technical term is twiddle.)
Although using decimal (e.g. 0-127) is the most human-readable way of specifying the values, some manuals for MIDI devices specify values for MIDI messages in other ways, which can also be entered directly in Sibelius. Values can be specified using seven decimal bits (preceded by b, e.g. b0111101) or hexadecimal up to 7F (preceded by h, e.g. h5C), but unless you’re a computer, you won’t want to think about this for too long.
Note that:

• MIDI messages are case sensitive (i.e. you must type capitals or small letters as indicated) – so

~C0,0 is correct but ~c0,0 won’t work

• Hex digits themselves (e.g. 5C) are case insensitive, but the h that precedes the digit must always

be lower case

• You can write multiple messages in the same piece of text, separated by a space or Return (on

the main board), and with just one tilde at the start, e.g.: ~P43 A65 C64,127

• If you like you can also put spaces or Returns around commas and numbers.

You may wish to switch off the Transpose chord/note names option in Text > Style > Edit Text Styles for your chosen text style to prevent the capital letter at the start of MIDI messages (e.g. ~C) being transposed as if it were a chord symbol – b 5.6 Edit Text Styles.
