You can include chord symbols in playback. They are played as sustained chords, with their duration taken from the gap between one chord symbol and the next. Chord symbols input via a MIDI keyboard use the voicing you played when inputting them, whereas chord symbols input via a computer keyboard use a default voicing.
Prerequisite
The Chords track is shown.
Procedure
In Play mode, activate Enable Chords Playback
in the Chords track header.
Result
Chord symbols in the project are included in playback. Dorico Pro automatically loads a piano sound in a new channel for chord symbol playback.
