Setting Control Surface Preferences
Various settings that affect the onscreen appearance and performance of control 
surfaces can be made in the Logic Pro > Preferences > Control Surfaces tabs.
To open the Control Surfaces preferences:
m
Choose Logic Pro > Preferences > Control Surfaces > Preferences (or use the Open 
Control Surfaces Preferences key command).
To temporarily disable your control surfaces:
m
Choose Logic Pro > Preferences > Control Surfaces > Bypass all Control Surfaces.
This command is useful for silencing motorized control surface faders when recording 
in the same room. It is also handy when troubleshooting MIDI data errors, or to reduce 
MIDI bandwidth requirements.
General Preferences
General control surface preferences include resolution of relative controls, maximum 
MIDI bandwidth, and other functions.
 Resolution of Relative Controls slider:  Sets the resolution of controls that change 
values in a relative manner. The default resolution is 128 steps. Choose a higher 
resolution value to divide the value range into finer increments. 
 Maximum MIDI Band Width slider:  Drag to set the maximum amount of MIDI 
bandwidth that your control surface can use. This is set to a default of 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 checkbox:  When active, touching a fader on the control 
surface selects the track corresponding to the fader. For this to work, the device must 
feature touch-sensitive faders.
 Control surface follows track selection:  When active, selection of a track in the Arrange 
window will automatically select the corresponding track/channel on the control 
surface.
