Choose Drum Notation from the Option menu to set up the display of your drum tracks in the Score Editor. Your drum tracks are the ones which have a single-line or five-line drum clef.
The top of the Drum Notation dialog shows the drum notes as they will appear when they are displayed. Below this are the MIDI note numbers for the drum notes. Below the note numbers is another display of the drum notes in music notation, so that you can more easily see what pitch your drum notes correspond to.
You can change the display of any drum note you want. Select the note you want to change by clicking on the note. The note will be highlighted in red. If the note you want to change is to the left or right of the screen, move the slider on the bottom of the dialog until the note appears and then select it. Now move the note to the line or space you want it to be displayed in the Note Display window by dragging it with the mouse. Select the note head you want by clicking on the diamond beside the note head you want in the Note Head area of the dialog. Select the accent you want by clicking on the diamond beside the accent you want in the Accent area of the dialog. You can reset the drum display to the defaults by clicking on the Reset button.
Note: If you have a single-line drum staff, all drum notes are drawn on the line, so the position you set in the Drum Notation dialog is not important.
