A duet file contains karaoke data for two (or more) singers. In the library, you can split a duet into separate tracks and, vice versa, merge tracks into a duet.

  • Menu > Extras > Merge selected files
  • Menu > Extras > Split into tracks

You can safely delete track files and regenerate them from the duet file. Or recover a missing duet file by merging the track files. If you edit track files with another tool, don’t forget to merge your changes back to the duet file.

Left side: The duet file [MULTI] contains notes/lyrics for singers P1 and P2. Right side: When editing a duet, it is split into separate track files [P1] and [P2].

As you start editing, a duet is automatically split into tracks. All tracks are shown on the timeline; the active track is editable. In the track overview you can activate a track, jump to any track’s page, and review track errors. Changes are saved per track and instantly merged back to the duet file.

The editor saves changes in [P1] and [P2], and also in [MULTI]. You can edit P1 (blue) in the timeline, or switch to P2 (green) in the track overview (bottom).

Set the track name to the singer’s name. If you start with a single track, you can add a second track later – the duet file is created automatically. If you delete a track, the duet file will be removed.

  • Menu > File > Rename Track…
  • Menu > File > Add Track
  • Menu > File > Remove Track…
Track-To-Singer Mapping

One track can target one or more singers. Two singers might sing lines together and still differ in timing and pitches (or even lyrics), resulting in different P1 and P2 data. If, however, they share a line exactly, karaoke players can show a single line for both. In the duet file, shared lines are stored as P3 data. P3 is a virtual track that has no track file; it is not shown in the track overflow. Instead, shared lines are directly shown in P1+P2.

More combinations for three (P4) or four singers (P8) are shown below. But wait… before you start creating elaborate ABBA songs… three or more singers are not supported yet. Yet.

P 4 and beyond can not be used in Yass Karaoke Editor, nor in your karaoke players (as far as I know, I’d be happy to hear different…)

Comparing Song Versions

You can use tracks to compare different karaoke files for the same song. Just select both in the song library and open the editor. Both versions are shown simultanously and you can quickly review the differences.

You cannot edit multiple tracks if they are part of a duet (= a matching duet file exists).
