Open the SysEx Fader Editor window
In Logic Pro, select the fader, then choose SysEx from either the Output or Input pop-up
menu in the inspector.
The SysEx Fader Editor window opens automatically.
You can also specify SysEx as an Input definition, but this has limited usefulness because
the incoming message (presumably SysEx) must be very short in order to be recognized.
(Because SysEx messages can be of any length, Logic Pro must break them into small
packets to avoid interrupting other MIDI activities.)
An important thing to remember about the SysEx fader is that only selected events have
their value altered by the fader value when the SysEx fader window is closed. Events that
are not selected are sent exactly as they appear in the window.
For SysEx messages, you can determine:
The bytes that are altered
The format (MSB/LSB, BCD, nibbles, and so on) of the value
You can also specify a checksum format, if necessary.
SysEx messages in the Logic Pro Environment
