Play mode
Play mode allows you to change how your music sounds in playback, including by changing the playback template and assigning VST instruments, inputting automation, adjusting the mix, and changing the sounding duration of notes in playback without affecting their notated duration.
Playing back music
You can listen to the music you have written from the beginning of your project or from a specific point. You can also use the playback key commands in any mode.
Changing the pre-roll duration
In Dorico Pro, pre-roll is the time added to playback before the first beat of the first bar in each flow. You can change the pre-roll duration, for example, if some flows in your project start with grace notes.
