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.
First Data Byte checkbox
and pop-up menu
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.
