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.
Tips for Numerical Input
Numerical input (by double-clicking) is always independent of the current display
mode or event type, and can be used in many other areas of the program. Here are
some of the possible methods. You can type in:
• Decimals: 1, 01, 2, 3, 4, 127, …
• Hexadecimals: $1, $01, $2, $3, $A, $0A, $7F
• Notes: “C3”, “C#3”, “Cb3”, “C##2” (equivalent to D2), “Dbb2” (equivalent to C2)
If you double-click on the note “E3”, you can enter a decimal value such as “64” or a hex
value of “$40” instead of the note itself.
In many parts of Logic, mathematical operations can also be used to change values. As
examples:
• adding two existing values: “
+
5”, “
+
$10”
• subtracting from the existing value: “
−
5”
• summing two values: “38
+
17”
• subtracting two values: “38
−
17”
• multiplying two values: “7
∗
8”
• dividing two values: “80/5”
