926 Chapter 39 Working in the Environment
For text style faders, the first name always corresponds to the low end of the range,
and subsequent names correspond to incremental range values, up to the top range.
The number of names that can be entered into the window is limited by the range.
Val As
This parameter determines the way that numerical values are displayed by the fader:
 Num: The fader value is displayed as a number (0 to 127).
 Pan: Fader value 64 is displayed as “0”; smaller values appear as negative numbers
and larger values as positive numbers (–64 to 63).
 Hz, Oct, dB, ms: These display formats are tailored to various DSP functions.
 bpm: An offset of 50 is added to the fader value. This displays the correct tempo
settings for the Special > Tempo Control fader.
If none of the above formats is suitable, consider using a text style fader, and entering
the desired display values as text. Examples include: percentages, note names, and
program names.
Fader Functions: Filter
This parameter provides various filtering options for MIDI events:
Off
All incoming MIDI events are allowed to pass through. All events that match the input
definition are converted, in accordance with the output definition.
Other
All MIDI events that do not correspond to the input definition are filtered. All events
that match the input definition are converted in accordance with the output definition,
and allowed to pass through.
Match
All MIDI events that match the input definition are filtered, all others are allowed to
pass.
All
All incoming MIDI events are filtered.
Thru
All MIDI events coming from the Physical Input object are filtered. This is the same as
turning off all events coming from Logic Pro (from regions or the Environment).
Use this filter mode to prevent MIDI feedback, by blocking incoming MIDI events from
being sent back out.
Shot
When the fader is moved with the mouse, only the final value (the value when the
mouse button is released) is sent.
