14 Bit: The result of using this filter setting depends on how it’s used.
Used in conjunction with pitch bend, 2-byte (fine-tuning) pitch bend events are
allowed.
Used with controller messages, the fader sends two MIDI controller messages:one
for the MSB (Most Significant Byte) and one for the LSB (Least Significant Byte).
Note: The faders Input and Output definitions must be the same or the 14 Bit setting
do not work.
For controllers, the MSB uses the Input definition controller number, and the LSB uses
the controller number 32 or higher. This conforms to the MIDI standard for sending 14-
bit controller data.
When this filter setting is chosen, the faders Range can be set to a maximum value of
16,383. A fader value of 8192 represents no pitch bend.
Feedback: When the Feedback parameter is turned off (unselected), the fader
automatically prevents feedback loops resulting from circular cabling. (The fader
remembers when a specific MIDI event has passed through it and does not allow it to
pass through again.)
In some instances, you may want to enable feedback—to allow a MIDI event to change a
cable switchers position after it has passed through the switch, for example. Selecting
the Feedback checkbox allows this behavior.
Vector fader in the Environment in Logic Pro
Vector faders function like joysticks. They can be moved in two dimensions:up and down
and left and right. Each dimension generates its own MIDI events, so each time you change
the position of the crosshair with the mouse, two MIDI events are sent.
Most faders have Input and Output definitions, which determine the MIDI events sent
by the fader (Output), and those it reacts to (Input). (See Fader: range, value as in the
LogicPro Environment.)
For vector faders, Input and Output definitions are replaced with Vert and Horz definitions,
which determine the MIDI events that correspond to vertical and horizontal motion. If
corresponding MIDI events are received by the vector style fader, its crosshair display
updates accordingly.
