Editing MIDI Events in the Event List
SysEx Data in Hex Format
You can choose whether SysEx data is displayed in hexadecimal or decimal, in the
Event List or the SysEx fader editors, with the View > SysEx in Hex Format command.
Hexadecimal digits are preceded by a $ symbol in Logic Express.

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 indeed.
 Num = 48 (Switch Fader): This will send MIDI events to a particular output number
(Val) on a cable switcher (see the Environment chapter for details). You first need to
connect a cable between a track instrument and the cable switcher in question.
 Num = 49 (Go to screenset): This event selects a screenset. Val determines the
screenset number.
 Num = 50 (Project Select): This event will switch projects on a MIDI data filer/player.
Val determines the stored project number.
 Num = 51 (Go to Marker): When this event is sent, playback will jump 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.
