The Audio Mixer

Logic Audio features an audio mixing console with full automation facilities. You can record fader and pan pot moves, mute and unmute tracks and DSP effects, send multiple tracks to different busses in series or parallel configurations and can even bounce your audio with all mix automation to a stereo file for CD mastering.


The Channel Strip

The different parts of the channel strip are indicated in the diagram below. Using this as a guide, you should have no trouble with the insertion of effects, use of the EQ, bus sends and channel volume. See the information following the image for specific details.

Equalization Section

Each channel can have up to four-band EQ. Clicking on the Thru panel opens a flip menu where you have five EQ types to choose from. The ON button to the top right is a toggle switch with which you can automate your EQ, or use to isolate particular frequencies.

Channel Inserts

Each channel in Logic Audio can have up to eight separate insert effects. Clicking on the panel/s below the "Inserts" text will open a flip menu showing you Logic Audio's extraordinary range of over 40 high-quality effects plug-ins. Just scroll to the desired effect in the list and release the mouse button to select an effect.

To edit the effect's parameters, double-click on the insert panel with the newly activated effect insert. Active inserts are shown in blue, as above, and indicate the name of the selected effect.

When an effect is opened for editing, a new window will appear onscreen. Many of Logic Audio's effects have an enhanced graphical interface that gives visual feedback of parameter changes, making editing easier.

All effects have an "Editor" mode, which displays effects parameters as a set of horizontal sliders. This mode is useful for displaying information in a smaller onscreen window.

Bus Sends

As with the other audio channel interface elements, clicking onto the panel beneath the "Sends" text will open a flip menu with a range of bus options. Logic Audio supports up to 16 bus sends per channel.

As these are activated, an onscreen pan pot will appear to the right of the bus selection panel. Clicking and dragging on this pan pot will adjust the bus send level.

To switch between pre and post fader modes, click on an ACTIVE bus selection panel, where a flip menu will appear allowing you to make the choice. By default, this is always set to post fader mode.

As each channel is capable of using multiple busses, setting up parallel effects configurations is as simple as the selection of two or more busses.

The busses themselves handle effects inserts like the channel strips and also have further bus send routings.

Input/Output Selection

If the computer system on which Logic Audio is installed has supported audio hardware with multiple audio inputs and outputs, each channel can use a specific mono in/output or stereo in/output pair.

From the output selection panel, you can also choose to use...

Surround Sound Panning

For supported audio hardware with multiple outputs, Logic Audio also features Surround Sound panning in all current formats.

Output selection is handled on a per channel or per bus level via an extremely easy to use graphical interface as shown below. Due to it's flexible implementation of surround panning on both channels and busses, it is possible to use multiple surround formats simultaneously in Logic Audio.

Accessing this enhanced Surround Panning view is via a double click on the surround pan control on the channel or bus strips.

The remaining channel strip controls are for volume, mute and solo and record arming, which should be straightforward enough to use.

The final control is for stereo/mono "ganging". This button, to the left of the REC button at the bottom of each fader is used to link adjacent audio channels for control using a single fader. i.e. channels 1 and 2, channels, 3 and 4, 5 and 6 a.s.o. can be controlled as stereo pairs using the left-hand fader.


Other Audio Objects

Apart from the standard audio objects discussed above, Logic Audio offers other types of audio objects. These are;

The Bus and Master objects behave as you would expect on a traditional mixing console, and adjustment of parameters plus the insertion of effects is as per the standard audio fader covered earlier.

The Audio Input objects are a different type of fader that, as the name suggests, offers control over the input of audio entering the program. With these objects, you can monitor your audio input signals through Logic Audio's internal effects.

The Audio Instrument objects support Emagic's EXS24 Extreme Sampler and ES1 synthesizer plus VST 2.0 compatible software "instruments". The EXS24 and ES1 are designed to be used exclusively in the Logic Audio sequencers.

Logic Audio supports up to 24 discrete Audio Instruments, dependent on available CPU resources and system RAM.

Audio Instruments are accessed via the insert points on Audio Instrument faders, just as you would insert an effect on a standard audio fader.

The advantage of the integration of sampling and synthesis within Logic Audio is that all of the tools necessary for audio recording, sample playback and synthesis plus effects and mixing can occur within your computer.

For more information about the EXS24 and ES1, please visit our website at:

Audio Mixing Facilities

You can automate volume, pan and many other MIDI-controllable effects parameters using dynamic events by selecting the "Audio Mix" track in the Arrange Window's Track List, dropping into record and moving your Audio faders, pots and buttons onscreen.

Alternately, you can use HyperDraw within the Arrange window to do the same job but with a couple of important differences.

Using HyperDraw is as per the instructions covered in the Arrange section.


Bouncing Audio

Included in Logic Audio is the bounce facility.

On each master fader, a "Bnce" button is available. When this button is pressed, a further window will give you options for the type of file you would like to create and also the left and right boundaries of the region you would like to select.

On clicking the OK button, Logic Audio will then play through your selected region and all audio routed to the selected Master output, including effects and mix automation, will be bounced to a new mono/stereo file.

This file can then be mastered to CD or further processed.
