To change the velocity of multiple notes in Logic Pro, you can use the Velocity tool in the Piano Roll Editor. Here’s how you can do it:
1. Open the Piano Roll Editor by double-clicking on a MIDI region or selecting it from the Window menu.
2. In the Piano Roll Editor, select the notes you want to adjust the velocity for. You can do this by clicking and dragging over the notes or by using the marquee tool (shortcut: M) to make a selection.
3. Once you have the notes selected, you can change their velocity using the Velocity slider in the header of the Piano Roll Editor. Dragging the slider to the left will decrease the velocity, while dragging it to the right will increase it. You can see the velocity values changing in real-time as you drag the slider.
4. If you want more control over the velocity adjustments, you can also use the Velocity tool. You can select it from the Tool menu or press Control-Command (⌃⌘) to temporarily change the Pointer to the Velocity tool.
5. With the Velocity tool selected, you can click and drag vertically over a note to change its velocity. Dragging upwards will increase the velocity, while dragging downwards will decrease it. This allows you to adjust the velocity of individual notes within the selected group.
6. You can also use the Velocity tool to create velocity ramps or curves by dragging diagonally over multiple notes. This can be useful for adding dynamics and expression to your MIDI performances.
7. If you want to reset the velocity of selected notes to a specific value, you can double-click on the Velocity tool icon in the Piano Roll Editor toolbar. This will open a dialog where you can enter the desired velocity value.
By using the Velocity tool and the Velocity slider in the Piano Roll Editor, you have precise control over the velocity adjustments for multiple notes in Logic Pro. Experiment with different velocities to add dynamics and expression to your MIDI tracks.
