SysEx Events
System Exclusive Data (SysEx) is exclusive to individual MIDI devices. You can record
these events using the dump utilities of your synthesizers, allowing you to save patch
information outside the MIDI device. The arrows in front and behind the word EOX are
used to add or remove bytes.
Editing SysEx Events requires a thorough understanding of the data format used by the
MIDI device in question. Incorrect edits can lead to the corruption or loss of sound
data.
SysEx Data in Hex Format
You can select 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.
For more information on manually programming a SysEx message, check out the
Environment SysEx Fader section.
Meta Events
Meta events are control messages that are specific to Logic. They are used to automate
specific Logic functions, and organize notation objects which can’t be represented by
MIDI events.
To create a meta event, hold down Command and click on the Full Message button.
