To temporarily disable your control surfaces
µ
Choose Logic Express > 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 for reducing
MIDI bandwidth requirements.
General Preferences
General control surface preferences include resolution of relative controls, maximum MIDI
bandwidth, and other functions.
• “Bypass All while in background” checkbox: Allows you to share your control surface with
other applications, when Logic Express is not the active program.
• 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.
