Go to Marker
Choosing New > Fader > Special > Go to Marker creates a fader that allows you to enter
a marker number (meta event 51).
The playhead moves instantly to the chosen marker number. Markers are numbered
sequentially, throughout the project, even if you have renamed them (from the default
numbers assigned when each marker was created).
Go to Screenset
Choosing New > Fader > Special > Go to Screenset creates a Screenset fader (meta event
49), allowing you to switch to the screenset number chosen with the fader.
Meta event 50 has no effect within Logic Pro, but you can use it to switch between songs
on an external hardware sequencer.
Meta event 52 allows you to interrupt playback at any position.
Note: To make the most efficient use of these faders, limit the value range to suit your
particular circumstances. For example, limit the faders to the number of markers or
screensets you’re actually using.
Working with SysEx Faders
The SysEx fader type is slightly different from other fader types. It allows you to create a
list of MIDI events that will be sent whenever the fader is moved or controlled remotely.
You can enter the messages that you want to send in a window that resembles the Event
List.
To open the SysEx Fader window
Do one of the following:
µ
Set a fader’s Output or Input definition to SysEx.
The SysEx Fader window opens automatically.
µ
Double-click the word SysEx in the fader’s parameter box.
