Meta Event Faders
Meta faders generate special meta events, which are used to control certain
Logic Express 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:
For more on Meta events 124 to 127, read the section on Remote Controlling the
Condition and Operation Values (see “
Transformer Object ” on page 918).
Meta event Controlled Logic Express function
46 Assign Alias
49 Go to Screenset
50 Go to Project
51 Go to Marker
52 Stop Playback
96 Set fader range minimum
97 Set fader range maximum
98 Set the fader value without sending.
99 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.
100 Tempo Control (see “ Using the Tempo Fader ” on page 681)
122 Set transformer map value for the currently selected map position.
123 Select transformer map position.
124 Set transformer condition maximum (bottom) parameter, if any. (This applies to all
conditions not set to All).
125 Set transformer condition minimum (top) parameter, if any. (This applies to all
conditions not set to All).
126 Set transformer operation maximum (bottom) parameter, if any. (This applies to all
operations not set to Thru).
127 Set transformer operation minimum (top) parameter, if any. (This applies to all
operations not set to Thru).
