Work with SysEx messages
There are several ways to enter SysEx messages in the SysEx Fader Editor window.
Teach the fader to learn a SysEx string
1 Click the MIDI In button at the top-right corner of the window.
2 Alter the parameter on your device.
The corresponding SysEx message is displayed. You can also enter SysEx messages in the SysEx
fader window by typing the SysEx string into the Event List. (Check your MIDI device manual for
SysEx documentation.)
Manually enter SysEx strings
m Choose Syst. Exclusive from the Event Type pop-up menu, then click the Add Event button.
Event Type pop-up menu Add Event button
A generic SysEx message appears.
•
The first data byte in the top line (directly after the word SysEx in the Num column) is
the manufacturer’s ID. This may be several data bytes long (as there are more than 128
manufacturers of MIDI devices).
•
The manufacturer’s ID is usually followed by a device type ID, an individual device ID, a data
type ID (which could be several bytes) and, if necessary, the number of the multi-timbral
subchannel, and the identification number or numbers of the sound parameters plus the value
of the sound parameter. There are no uniform standards that apply here.
•
Data bytes are normally input as decimal numbers. To enter them in hex, place a $ in
front of values when you type them. Choose View > SysEx in Hex Format to see all values
in hexadecimal.
•
The last data byte (the EOX indicating the end of the SysEx message) is entered automatically
by Logic Pro. The number of data bytes in the SysEx message can be decreased or increased
by clicking the Plus and Minus buttons before and after the word EOX.
