Meta Event Faders
Meta faders generate special meta events, which are used to control certain Logic Pro
functions, but have no MIDI meaning, and are never sent to the MIDI output.
In some cases (such as Go to Screenset, Go to Project, and so on), you do not need to
cable meta faders into another object for them to work. Even in these cases, you can
use cabling to process meta events in the Environment, and alter their effect.
In the majority of cases, however (Set fader range minimum, Bang!, Set Transformer
Operation Minimum, and so on), the meta fader must be cabled to the object being
affected.
Here’s a quick summary of the currently implemented meta events that can be
generated by faders:

Bang! Causes the fader to re-send its current value. The bang data value can be used
to make the fader increment-without-rollover (127), decrement-without-rollover (125),
increment-with-rollover (123) or decrement-with-rollover (121). Use values one less
than those shown, to have the bang” passed through to all connected faders.
