These functions do not alter the bar position of the affected symbols and text events,
but their hor.pos. and vert.pos. parameters by ±1.
Editing or Deleting Notes and Symbols
Editing Using Tools
Velocity Tool
If you grab one or several notes with the Velocity tool, and move the mouse up or
down, you change the notes’ velocity values.
The value change can be seen in the help tag, and can also be heard if the MIDI Out
button is activated.
You don’t need to go to the Toolbox to get the Velocity tool: when you grab a note
while holding down Option-Control, the cursor becomes the Velocity tool. Once you
release these modifier keys, the cursor takes on its previous shape and function again.
Quantize Tool
For Quantizing and De-Quantizing (see “Event and Note Quantization” on page 43) the
MIDI playback of selected notes.
Layout Tool
With the Layout tool, you can change the horizontal graphic position of a note in
relation to its bar position.
Pulling the note to the right or left with that tool changes the displayed distance from
the adjacent notes or rests. The bar position (and the playback) will remain unaltered.
This is used, for example, to create space for a grace note, or for an arpeggio line. Also,
when symbols are moved with the Layout tool, their bar position will not be altered.
Instead, the hor.pos and vert.pos parameters are changed, which is indicated in the
help tag during this process.
There is a shortcut for grabbing this tool: pressing Control while grabbing the note
converts the cursor into the Layout tool.
