Meta events
Meta events are control messages that are specific to Logic Pro. They are used to automate
certain functions, and to organize and arrange Score Editor elements (particular notation
symbols and formatting) that can’t be represented by MIDI events.
The value in the Number column determines the meta event function, and the value in the Value
column determines the value that is sent. You should only ever insert and edit the following
column values in the Event List.
•
Ch(annel): MIDI channel of an event from 1 to 16.
•
Num = 47 (Send Byte to MIDI): This sends the track instrument any byte value (Val) between 0
and 255 ($00-$FF). As a usage example of this meta event: If you send 246 as the byte, this is
equivalent to a MIDI tuning request message. The display will show Send Byte $F6. Only use
this meta event if you know what you’re doing—if you don’t, your sound modules and synths
may start to behave very oddly.
•
Num = 48 (Switch Fader): This sends MIDI events to a particular output number (Val) on a cable
switcher. You first need to connect a cable between a track instrument and the cable switcher
in question. For details about cable switchers, see
on page 797.
•
Num = 49 (Go to screenset): This event selects a screenset. Val determines the screenset number.
•
Num = 50 (Project Select): This event switches projects on a MIDI data filer or player. Val
determines the stored project number.
•
Num = 51 (Go to Marker): When this event is sent, playback jumps to another marker. Val
determines the marker number.
•
Num = 52: This meta event stops playback.
Meta events can also be generated by fader objects in the Environment. See
