You can click on the symbol or on your numeric keypad type “1” for one bar repeat, “2” for bar repeat, or “4” for bar repeat. Music notation purists will tell you a four bar repeat is incorrect notation, but I’ve seen it come in handy many times in real world charts—especially arrangements for live performance.
If you look at the example above, you’ll see a number in parenthesis (2, 3, etc.) over the bars. This helps the drummer see at a glance how many times the figure is repeated.
The parameters of this feature are defined in the Engraving Ruleson the “Bar Rests” page. You can set your one bar repeats to be numbered every 1, 2, 3, 4, or 8th bar. For most drum charts it’s less cluttered to number the bar every four or eight bars.
Underneath the table are new options to this release that are now also present when you import a MIDI file and MusicXML file. These allow you to control the preview on the right hand side. For very large scores, importing can take a second or so for each assignment, so you can now untick “Generate Preview after every change”, and you will notice that the score preview is blurred out. Now each assignment is instant, and you can click “Generate Preview” to check on progress.
