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 gap or over-
lap 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
gap in beats and ticks.
Transform Sustain Pedal To Duration
The
Transform Sustain Pedal To Duration
option
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 sustain pedal
goes up (0 to 63). Enable the
Delete Sustain Pedal
Events
option to convert sustain pedal events to
note durations. Converting sustain pedal events
to note duration can greatly simplify editing
while maintaining the desired performance ef-
fect. For example, if a sustain pedal down event
is deleted while editing, the subsequent MIDI
performance looses its legato effect.
Change Continuously Option
The Change Continuously option lets you change
the duration of notes continuously in ticks or by
percentage. Adjust the Curve slider to modify
the shape of the change.
Change Continuously in Ticks
Allows note
lengths to change smoothly from one duration
to another over time. Duration values are speci-
fied in quarter notes and ticks.
Change Continuously by Percentage
Allows note
lengths to change smoothly from one percent-
age value to another over time.
The curve for this change can be adjusted
(+/– 99) to affect how gradually the change oc-
curs.
Limit Range When selected, restricts the Change
Duration
command to a minimum and maxi-
mum range (in quarter notes and ticks).
Randomize When selected, the Change Duration
command is randomized by the specified per-
centage value. For example, using “Set all to”
with a value of 480 ticks, along with a Random-
ize value of 50%, yields durations anywhere be-
tween 360 and 600 (+/– 25% of the duration
value).
Change Duration Examples
To make notes more staccato:
1
Select the range of MIDI notes to be edited.
2
Choose
Event > Event Operations > Change Du-
ration .
3
Select the option for
Scale By
with a percent-
age value of 50.
Press Alt+P on Windows or P on
Mac to open the Change Duration window.
