How to get there

Click the MIDI Tool $image\MIDI_Tool.gif$ . Select a region of measures. (If you’re editing only a single staff, double-click the highlighted area to enter the MIDI Tool window.) Specify the MIDI data type you want to edit by choosing Note Durations from the MIDI Tool menu. If you’re in the MIDI Tool window, select the region you want to affect by dragging through the "graph" display area or by selecting the handles of individual notes whose MIDI data you want to edit. Choose Percent Alter from the MIDI Tool menu.

What it does

This dialog box’s function is to change the duration of every note in the selected region by a percentage of its current value. Because it changes the data of every selected note by a percentage, the Percent Alter command preserves the relative proportions of the existing values.

___ percent of current value. In this text box, enter the percentage by which you want the note durations changed for the selected notes. This value can be any number above zero—you can enter 300%, for example, to make a particular value three times its current value. The number in this text box represents the amount by which you want to shorten or lengthen the playback durations of all selected notes (regardless of their notated durations). Note that this is the only MIDI Tool command that directly modifies the durations of existing notes (the other commands modify the notes’ durations indirectly, by manipulating their Start and Stop Times). For example, if you want a region of eighth notes and quarter notes to play back staccato, enter 50 (%) in this box; the notes will be sustained for only half their original durations.
OK • Cancel. Click OK to confirm, or Cancel to discard, the MIDI data changes you’ve specified. You return to the MIDI Tool window (or the score).
