Change Duration
The Change Duration command adjusts dura-
tions for selected MIDI notes. Use it to affect the
articulation of the selected notes by making
them more staccato or legato.
Set/Add/Subtract/Scale Option
Set All To Sets all durations to a length specified
in quarter notes and ticks.
Add Adds to the durations by a specified number
of quarter notes and ticks.
Subtract Subtracts from the durations by a spec-
ified number of quarter notes and ticks.
Scale by Shortens or lengthens durations based
on a percentage value (1–400%).
Legato
Enable the legato option to add legato to the
MIDI selection. Select Gap or Overlap from the
Legato pop-up menu and enter the desired gap
or overlap in beats and ticks.
Remove Overlap
The Remove Overlap option removes any note
overlap for all notes of the same pitch. This
command is different from Legato in that non-
overlapping notes of the same or different
pitches remain unchanged. To create a gap be-
tween previously overlapping notes, enter the
desired gap in beats and ticks.
Transform Sustain Pedal To Duration
The Transform Sustain Pedal To Duration op-
tion extends the length of all notes that are
sounding when the sustain pedal (controller 64)
is down (64 to 127) to the point when the sus-
tain pedal goes up (0 to 63). Enable the Delete
Sustain Pedal Events option to convert sustain
pedal events to note durations. Converting sus-
tain pedal events to note duration can greatly
simplify editing while maintaining the desired
performance effect. For example, if a sustain
pedal down event is deleted while editing, the
subsequent MIDI performance looses its legato
effect.
MIDI Operations window, Change Duration
The settings in the Change Duration page
are saved with each session. To store your
favorite settings as the default for use in fu-
ture sessions, save them as part of a session
template (see “Creating Custom Session
Templates” on page 91).
You can also change note duration nonde-
structively in real-time using MIDI Real-
Time Properties. See “MIDI Real-Time
Properties” on page 607.
