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.
Show the first data byte and set a value
The First Data Byte checkbox and pop-up menu are shown at the bottom of the inspector.
The name of the First Data Byte parameter reflects the chosen Status parameter, as
follows:
Fader, Meta, Control, Program: A number is shown as the first data byte.
Note, P-Press: Pitch is shown as the first data byte.
C-Press and PitchBd: The first data byte is dimmed, as it has no function.
1. Select the First Data Byte checkbox to show the defined first data byte. Select the box
a second time (unselected) to hide the first data byte. In the case of note events, the
velocity values of all notes (regardless of pitch) are displayed in the relevant lane.
2. Choose a value from the First Data Byte pop-up menu. The choices shown in the pop-
up menu depend on the parameter shown in the Status line:
If Control is chosen in the Status line, the First Data Byte pop-up menu determines
the controller type (controller number).
If Meta or Fader is chosen in the Status line, the First Data Byte pop-up menu
determines the meta or fader event type (meta or fader message number).
If channel aftertouch (C-Press), or program change events (Program) is chosen in
the Status line, the First Data Byte parameter setting is ignored and the first data
byte is displayed as a beam height.
When pitch bend data (PitchBd) is chosen in the Status line, the First Data Byte
parameter setting is also ignored because both data bytes are used to display the
beam height.
