Using a Control Surface with the Audio Mixer
A control surface is a hardware device with faders, knobs, and buttons that can control
the Final Cut Pro Audio Mixer. You can use a supported control surface to remotely
control track faders, pan settings, mute and solo buttons, and even the transport
controls in your sequence. Control surfaces emulate traditional audio mixing consoles,
giving you tactile control over multiple faders at once.
Connecting a Control Surface
Control surfaces send and receive MIDI data to communicate fader positions, pan knob
settings, track names, and timecode.
To set up your control surface, you need the following:
 An external MIDI interface with at least one input and output
 Mac OS X MIDI driver software that corresponds to your MIDI interface (if necessary)
 One or more supported control surfaces
Select one or both of
these checkboxes to
delete keyframes from
overlays.
What Is MIDI?
Musical Instrument Digital Interface (MIDI) is a standard protocol that allows
electronic music devices and control surfaces to send and receive performance data.
This allows you to do things such as control a synthesizer with a keyboard or control
an audio mixing application such as Final Cut Pro with a control surface.
