Note On
Applies the Change Velocity options to
the MIDI Note On.
Note Off
Applies the Change Velocity options to
the MIDI Note Off.
Set All To Sets all velocities to the specified value
(1–127).
Add
Adds to existing velocity values by the spec-
ified amount (1–127).
Subtract
Subtracts from existing velocity values
by the specified amount (1–127).
Scale By
Scales all velocities by a percentage
amount (1–400%).
Change Smoothly
Allows velocities to change
smoothly from one value to another over time.
Change Smoothly by Percentage
Allows veloci-
ties to change smoothly from one percentage
value to another over time.
The curve for this change can be adjusted
(+/– 99) to affect how gradually the change oc-
curs.
Limit To
When selected, restricts the
Change Ve-
locity command to a minimum and maximum
range after the selected Change Velocity option
has been applied (and also after any randomiza-
tion has been applied).
Randomize
When selected, the selected Change
Velocity option is randomized by the specified
percentage value after the selected Change Ve-
locity option has been applied. For example,
with the
Set All To
option enabled and set to a
value of 64, and with
Randomize
enabled and set
to a value of 50%, the resulting velocities will be
anywhere between 48 and 80 (+/– 25% of the
velocity value).
To randomize selected velocities without applying
any other Change Velocity options:
1
Enable the
Scale By
option and set it to 100%.
2
Enable
Randomize
and set the amount of ran-
domization you want.
3
Click
Apply
.
Velocity Ranges
The valid range for MIDI note velocities is
1–127. The Change Velocity command will
never result in moving velocities outside this
range; 1 is always the lowest and 127 is always
the highest. This means that you can encounter
situations where the Change Velocity command
has no effect on a particular note.
For example, if a note with a velocity 64 is scaled
by 200%, the new velocity would be 127. At-
tempting to scale or increase the velocity any
further yields no further change.
Fading Velocities
To change velocities smoothly over time:
1
Select the range of MIDI notes to be edited.
2
Choose Event > Event Operations > Change Ve-
locity
.
3
Select the
Change Smoothly
option with the
range set from 127 to 0.
4
Click Apply .
While there are options for adjusting both
the Note On (attack) and Note Off (release)
velocities for notes, most MIDI devices ig-
nore release velocity information. To see if
your instrument supports release velocities,
refer to the manufacturer’s documentation.
