Changing Event Definitions
You use the Event Definition Parameter box in the Inspector to alter the settings of the
selected event definition lane. The most important parameters are Status (and First
Data Byte). All display related parameters are covered in “
” on page 439. Information on all other parameters is found later in this section.
Altering the Event Status
The event status determines the type of event controlled by each event definition lane.
Click-hold the arrows to the right of the Status line, and choose one of the following
from the pop-up menu:
 Fader: To define a fader event lane. Fader event data can be used to control any
possible parameter (except channel volume and pan, which use controllers). Fader
data can also be used to create meta events.
 Meta: To define a meta event lane. Meta events are internal Logic Express commands
that can perform tasks such as screenset switching.
 Note: If you want to define a lane for a particular note pitch (perfect for drum
programming).
 Control: If you want to define a MIDI controller lane.
 C- Press (Channel Pressure): To define 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: To define 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: To define a lane for pitch bend information.
Important:
The choice made in the Status line directly affects the behavior (and
appearance) of the First Data Byte parameter.
As an example, if Note is chosen in the Status parameter line, you can use the first data
byte to determine the pitch (MIDI note number) of the selected event definition lane. If
the MIDI region is played by a mapped instrument, a pop-up menu of input note
names (drum sound names) appears here.
