Music Stand by Worship Extreme allows you to easily build worship set lists using CCLI's Song Select. All that is needed is the name of the song, then Music Stand will find the chart and transpose to the desired key.
Musicians can easily switch between lyrics only, one column chord charts, two column chord charts, and Nashville number charts.
Each musician can easily take notes, add comments and markup their music. Guitar players can set a capo, automatically having their charts transposed.
Worship leaders can add songs or change keys on the fly and all devices will be updated instantly with the changes.
