Set the MIDI channel number for a lane
1 Select the MIDI channel checkbox.
•
If selected, the display is restricted to events on the set channel.
•
If unselected, the Channel parameter is ignored, and matching events on all channels
are displayed.
2 Choose a MIDI channel number from the pop-up menu to the right of the Channel parameter.
Simultaneously change the parameters of multiple lanes
Just as you can adjust the parameters for several MIDI regions at once, you can set the
parameters of several lanes simultaneously.
Do one of the following:
m Hold Shift, then click several lanes in the Name column.
m Choose Lanes > Select All Lanes, then deselect lanes you don’t want to change by
Shift-clicking them.
Any alterations you make in the inspector affect all selected lanes.
Change the event type
The event status determines the type of event controlled by each lane.
m Drag the event type shown beside the Status parameter vertically to choose one of the
following:
•
Fader: Defines a fader event lane. Fader event data can be used to control any possible
parameter (except channel volume and pan that use controllers). Fader data can also be used
to create meta events.
•
Meta: Defines a meta event lane. Meta events are internal Logic Pro commands that can
perform tasks such as screenset switching.
•
Note: Defines a lane for a particular note pitch (useful for drum programming).
•
Control: Defines a MIDI controller lane.
•
C-Press (Channel Pressure): Defines a lane for channel pressure (also known as aftertouch), a
feature of many synthesizers that adds vibrato, for example, when you press down on MIDI
keyboard keys that are already held.
•
P-Press (Polyphonic Pressure): As above, but each note can be independently modulated.
•
Program Change: Defines a lane that is used to create and send MIDI program change events,
allowing you to switch between sounds (electric piano and clavinet, for example) midway
through a region.
•
Pitch Bend: Defines a lane for pitch bend information.
Important: The chosen Status parameter value (event type) directly affects the behavior (and
appearance) of the First Data Byte parameter. For example, if Note is chosen as the Status
parameter type, you can use First Data Byte to determine the pitch (MIDI note number) of the
selected lane. If the MIDI region is played by a mapped instrument, a pop-up menu of input note
names (drum sound names) appears here.
