You can define and use chord voicings in RapidComposer. Voicing is “simultaneous vertical placement of notes in relation to each other”. More than 20 predefined chord voicing files are included as .rcVOIC files in the RapidComposerV3/DB folder. There are two types of voicing in RapidComposer: voicing for a concrete chord, or universal voicing that works with any chords. Using acoustic guitar chords was an option in earlier versions, but from v3.4 guitar chords are handled as a 'voicing'.

The visual voicing editor opens when you click on the small V button in the Master Track, which allows you to conveniently set chord notes:

It is possible to assign a voicing to master track chords in the Quick Suggestions pop-up. Clicking on a chord will open Quick Suggestions, which offers a voicing editor:

You can also edit voicing by right clicking on a chord and using the voicing menu:

A voicing editor is added also in the Chord Selector, together with Chord Builder:

Universal voicings work with any chords, so during editing you work with 1st, 3rd, 5th, 7th, etc chord notes, rather than with concrete chord notes:

Save the voicing using the Save… button. Universal voicing can be assigned to tracks or phrases (in the Track Inspector and Phrase Inspector), or even to a chord on the master track by selecting a preset from the voicing menu. By default phrases use the track voicing, tracks use the master track voicing. 'Acoustic Guitar' is a special voicing where the chord notes are looked up from the guitar chord database.

In v3.5 you can not only use chord notes, but also add non-existent chord notes, e.g. a 7th note to a major chord. This means a phrase can use the 7th note, even if the master track chord is a simple major or minor chord. This means amazing flexibility. Use the “Add Extra Note” buttons.
