Fader functions: range, value as
The following parameters determine the minimum and maximum values of a fader, and how the
fader displays these values:
•
Range: Contains two numbers—the left one sets the lowest possible fader value, and the right
one sets the highest. Note that these limits can be exceeded by MIDI remote control. When
the fader style is a button, the range determines the in and out position values of the button.
For text style faders, the rst 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.
•
Value as: 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 oset 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: lter
This parameter provides various ltering options for MIDI events:
•
O: All incoming MIDI events are allowed to pass through. All events that match the input
denition are converted, in accordance with the output denition.
•
Other: All MIDI events that don’t correspond to the input denition are ltered. All events
that match the input denition are converted in accordance with the output denition, and
allowed to pass through.
•
Match: All MIDI events that match the input denition are ltered; all others are allowed
to pass.
•
All: All incoming MIDI events are ltered.
•
Thru: All MIDI events coming from the Physical Input object are ltered. This is the same as
turning o all events coming from Logic Pro (from regions or the Environment).
Use this lter 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 nal value (the value when the
mouse button is released) is sent.
•
14 Bit: The result of using this lter setting depends on how it’s used.
•
Used in conjunction with pitch bend, 2-byte (ne-tuning) pitch bend events are allowed.
•
Used with controller messages, the fader sends two MIDI controller messages: one for the
MSB (Most Signicant Byte) and one for the LSB (Least Signicant Byte).
Note: The fader’s Input and Output denitions must be the same or the 14 Bit setting will not
work.
For controllers, the MSB uses the Input denition controller number, and the LSB uses
the controller number 32 or higher. This conforms to the MIDI standard for sending 14-bit
controller data.
