Change the note velocity in the Piano Roll Editor in Logic Pro for iPad
Velocity indicates how hard a key or a pad was struck when the note was played on a physical controller, which usually corresponds to the note’s loudness (the MIDI velocity range is 1–127, with 127 being the loudest). Velocity can also control other synthesizer parameters, such as filter resonance or cutoff, alone or in conjunction with volume level.
In Logic Pro for iPad, inside the horizontal note bar that represents the MIDI note in the Piano Roll Editor is a horizontal line (visible if you zoom in close enough). The vertical position of the line relative to the overall height of the note bar shows the note’s velocity. You can also display velocity using different colors, by choosing Set Note Color > By Velocity from the More menu 
in the Piano Roll Editor menu bar. Colors gradually change from purple to green to red.
Color coding makes it easy to see the velocity of individual notes and the overall range of velocities in a MIDI region. As you change the velocity of the notes, their color changes in real time.
Note: Note velocities can be offset during playback by the Velocity Offset parameter and Dynamics parameter in the Region inspector.
Change note velocity graphically
In the Piano Roll Editor menu bar, tap the Velocity button
.Tap a note to select it, or select multiple notes.
Drag one of the selected notes up or down.
The vertical line in the note bar moves up or down accordingly, and a help tag appears, showing the velocity value.
When you edit the velocity of multiple notes, the relative differences in their velocity values are retained. If the velocity value of any of the selected notes reaches the minimum or maximum value (1 or 127), none of the notes can be adjusted further.
Change note velocity in the Note inspector
In the Piano Roll Editor menu bar, tap the Trim button
.Tap a note to select it, or select multiple notes.
Tap the Inspector button
in the view control bar to open the Note inspector.Tap the Details disclosure arrow to show the Details parameters.
Drag the Velocity value up or down, or tap the Velocity field to open the numeric input dialog and enter a numeric value.
Note: You can change the display of the Velocity field to show values in higher MIDI 2.0 resolution. See View settings.
