First Data Byte
The bottom line shows the -1- parameter, where you can determine the first data byte
of the displayed event.
As an example, if Note is set as the event status, you can determine the pitch (note #)
that should be displayed in this event definition line. If the edited MIDI Region is played
by a mapped instrument, a pull-down menu that features the names of the input notes
(drum sound names) appears here.
As with the MIDI channel, the checkbox determines whether (if checked) only events
with the defined first data byte should be displayed, or whether (if unchecked) the
setting should be ignored. In the case of note events, the velocity values of all notes
(regardless of pitch) would be displayed in the relevant event definition line.
If Control is set as the event status, you can use a pull-down menu to determine the
controller type (controller #).
With channel aftertouch (status C-Press), or program change events (status Program)
the setting of the -1- parameter is always ignored, and the first data byte is displayed as
a beam height. With pitch bend data (status PitchBd), the setting is also ignored,
because both data bytes are used to display the beam height.
Making Different Definitions Simultaneously
Just as you can adjust the parameters for several MIDI Regions at once, you can set the
parameters of several event definitions simultaneously. Select several event definitions
in the name column, by holding down Shift and clicking on them. You can also use
Hyper > Select All Event Definitions to select all event definitions, and then deselect some
of them by Shift-clicking on them.
Any alterations made in the Event Definition Parameter box affect all selected event
definitions.
