Value As
This parameter determines the way that numerical values are displayed by the fader.
• Number: 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, Octave, 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 display values you want 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.
• 14 Bit: The result of using this filter setting depends on how it is used.
• Used in conjunction with pitch bend, this allows 2-byte (fine-tuning) pitch bend
events.
• Used with controller messages, this causes the fader to send two MIDI controller
messages: one for the MSB (Most Significant Byte) and one for the LSB (Least
Significant Byte).
Note: The fader’s Input and Output definitions must be the same or the 14 Bit setting
will not work.
