Control Surface Preferences
The Control Surface preferences window is accessible via the Logic Menu > Preferences >
Control Surfaces > Preferences menu.
General
Resolution of Relative Controls
This defines the default resolution of controls that change values in a relative manner.
The default is 128 steps.
As an example: adjusting the Sample Delay (value range 0 to 4000 ms) in/decreases
the value by 40 ms with every encoder rotation “tick”, if resolution is set to 100.
Maximum MIDI Band Width
This slider determines the maximum amount of MIDI bandwidth that can be used by
your control surface. By default, this is set to 50%, which should be suitable for most
situations. You can adjust the value if you find that your MIDI or Automation playback is
being affected.
Touching fader selects track
Activation of this parameter will automatically select the track that corresponds to the
selected fader. You require a device that features touch-sensitive faders for this
functionality to work.
Jog resolution depends on horizontal zoom
If your control surface features a jog/shuttle wheel (or similar), the precision of any
scrubbing is affected by the horizontal zoom level of Logic. To retain a consistent
resolution, regardless of Logic window zoom levels, disable this checkbox.
Pickup Mode
Enable this option to activate Pickup Mode. Pickup Mode is used by Controller
Assignments that use a scaled value mode and have either; no feedback or local
feedback (when the user operates the control, feedback occurs locally due to the
control’s mechanical nature). In Pickup Mode the current value must be reached
(“picked up”) by the control before a value change can occur. This link is broken (Pickup
Mode is non-functional) whenever the parameter changes its value by playing back
existing automation data. In this mode, move the control towards the parameter’s
current value (which is then “picked up”) if you want to change the parameter with the
control. When the Pickup Mode option is disabled, adjusting a fader modifies the
parameter immediately.
