Arpeggio, strum arrow, glissando (slide), portamento (glide), brass or wind instrument articulation (Fall, Doit, Plop and Scoop) and guitar slide in or slide out symbols are usually added from the "Arpeggios & Glissandi" palette.
To add to the score, use one of the following methods:
To adjust the length and height of a symbol:
After selecting a symbol, various useful properties can be adjusted in the "Glissando" or "Arpeggio" section of the Inspector.
Inspector:Glissando section
Inspector:Arpeggio section
If needed for future use, you can save the result in a custom palette.
When an arpeggio or strum arrow is added to the score, it initially spans only one voice. To change the height, see Adjust dimensions (above). Playback of the symbol can be turned on or off in the Inspector.
Add the arpeggio to the top staff, select it and use Shift+↓ to extend it downwards to the next stave without it affecting distance between those staves.
Note: For this to work the notes in the 2 staves need to be in the same voice. And it won't affect playback.
To add a slide or "portamento" between two notes, add a glissando symbol and change its appearance and playback.
To add a slide or portamento before or after a note before a note (a string instrument or guitar technique), add either one of the four wind instrument articulation symbols (Fall, Doit, Plop and Scoop) or a slide in/slide out. Alternative wavy symbols are found in the Symbols category in Master palette window. All of these do not affect playback, but you can mimic to an extent with a hidden Bends (found in Articulations Palette).
To control piano and vocal portamento playback, try Articulations and ornaments and Piano Roll Editor.
A Glissando or slide may be wavy or straight, and be with or without text. E.g.:
To move an end handle vertically or horizontally, from one note to the next:
This method change length and anchors together.
Use adjustment method (repeatedly) to create one.
Fall, Doit, Plop and Scoop symbols are provided. To change the length and curvature, select the symbol, enter edit mode and adjust the handles as described in Slurs: method 1. Do not affect playback.
Slide in and Slide out lines for guitar. To edit the length and angle of a line, double-click on it and drag the handle (or use the Inspector or keyboard arrows for finer adjustment). Do not affect playback.
