The Arranger
Build the lineup
Add every instrument seat the tune needs.

- Open the Arranger and pick the song.
- In Lineup builder, type an instrument.
- Set its role: lead, section or rhythm.
- Press Add chair.
- Repeat for every seat in the arrangement.
Tip. Name chairs the way players search, for example Tenor Sax, not TS.
You will end up with: A full lineup of chairs, each ready for a chart.
