Meta Events
Meta events are control messages that are specific to Logic Express. They are used to
automate specific Logic Express functions, and to organize and arrange Score Editor
elements (particular notation symbols and formatting) which can’t be represented by
MIDI events.
The Num(ber) determines the meta event function, and Val(ue) determines the value that
is sent. You should only ever insert and edit the following Num(ber) column values in the
Event List.
• 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 full details about cable switchers, see
Cable Switchers .
• 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.
