Event Operations : Step Input Command : Step Input Controls : Step Increment Section Controls
 
Step Increment Section Controls
The controls in the Step Increment section let you set the spacing and duration of MIDI events entered using the Step Input operation. You can select any size from whole notes to sixty-fourth notes (including dotted values).
Tuplet
Lets you input irregular note groupings (such as triplets or quintuplets). The tuplet length is calculated from the note spacing selection and the Tuplet values. For example, an eighth note equals 480 ticks, so tuplet eighth notes with 3 in time of 2 would yield a note spacing of 320 ticks (480 ticks / 3 * 2).
Note Length
Lets you select the note length as a percentage of the spacing value. For example, an eighth note equals 480 ticks, so an eighth note with an 80% duration would be 384 ticks long.
