Lesson 8

Changing Software Instruments And Loops To Audio
Up to this point we have been working with MIDI data only, not audio. Logic allows you to export an entire project as an MP3, Wave, or AIF file. You can also covert a single Software Instrument track into an audio file.
Bouncing A Project
Let's start by bouncing an entire Logic project down to a stereo file. This is a simple way to export your project to an MP3, WAV, or AIF file.
Open up your C Major scale project from the last lesson. If you have deleted it, simply recreate it again.
I am going to add a simple drum loop to this project, so that I will have two MIDI tracks (I am using a MIDI loop rather than an audio loop). My
Arrange window looks as follows:
Screen Shot 2014-02-07 at 4.18.22 AM
Yes, this is a simple Logic project, but it will serve as an easy example on how to bounce a project down to a stereo file.
Once you are happy with your mix, you can now bounce the entire Logic project down to a stereo file.

Set your
Cycle from your song start to your song end. This will tell logic when to start and stop the bounce. In this case, it is short!

Customize Toolbar

I like to have my Bounce icon located in my Toolbar.

Note, if your Toolbar is not showing click on the Toolbar icon (third from the right) to show your Toolbar

Screen Shot 2014-02-07 at 4.24.16 AM

To customize your Toolbar, Control-Click on the Toolbar. You will now see the following icon.

Screen Shot 2014-02-07 at 4.21.35 AM Click on it and you will now see the Customize Toolbar edit window

Bounce and click OK

Screen Shot 2014-02-07 at 4.21.45 AM

 The Bounce icon will now appear in your Toolbar
Screen Shot 2014-02-07 at 4.21.59 AM

Click on the
Bounce icon in your Toolbar or go to File, Bounce, Project or Selection. Or use the keyboard command Command B

You will now see the following dialog box:
Screen Shot 2014-02-07 at 4.32.08 AM

Logic provides you with a variety of methods to bounce your projects. I prefer the above settings. This will give me an
Interleaved Stereo AIFF file.

Wav Files

The Wav format is a PC file format, but can also be read my Macs. I prefer this method for film scoring projects since Wav Files are Timed Stamped.
I will cover this more later in the tutorial when I introduce film scoring techniques. Basically this means that when you import a Wav File into Logic it will contain
SMPTE info to place the file in the correct location on your movie.

Bouncing As A WAV File

To bounce as a Wav File select the following settings:

Screen Shot 2014-02-10 at 3.59.46 AM

Feel free to experiment with the different bounce settings.
I am going to Bounce my short piece as a
Wav file.
Once I choose the settings in the Bounce Window. I then click Screen Shot 2014-02-10 at 4.06.40 AM

You will then see the following dialog box:
Screen Shot 2014-02-10 at 4.06.24 AM
Click on
Bounce again. 
Logic will now bounce your project down to a stereo
Wav file located in your Bounces Folder in your Logic Project Folder
Screen Shot 2014-02-10 at 4.09.11 AM
A very easy and straightforward process!
Bouncing A Pre-Recorded MIDI Track
For this next example I am going to show you how to bounce individual Software Tracks that you have already recorded, but want to turn into audio tracks.
Why would you want to do this? A lot of time when I deliver a project to a client, they want audio stems of each track. This is one method of changing a Software Instrument track into an audio track. I will also show you another method that you can do on the fly!
Let's start by turning our piano track into an audio track.
Solo the piano track by clicking on the s button next to the track name in the Arrange Window.

 Screen Shot 2014-02-10 at 4.10.15 AM

By doing this, Logic will only play the piano track.
My piano track is only four measures so set up the
Cycle region for four measures.
Screen Shot 2014-02-10 at 4.10.55 AM

This way we are not recording empty measures that take up valuable audio space in a project.
Click on the
Bounce Regions icon located in the Toolbar Window.
 Screen Shot 2014-02-10 at 4.11.27 AM

You will now see the
Bounce Regions In Place dialog box. But this time note the changes that I have made:

 Screen Shot 2014-02-10 at 4.14.47 AM
I have named the track
OK and notice that the Piano Audio track has been added to your Tracks.

Screen Shot 2014-02-10 at 4.15.01 AM

Piano Audio has also been added to the Audio Files in your Logic Project. Select the Browser Icon located in the upper right hand corner of the Arrange window.
Screen Shot 2014-02-10 at 4.18.31 AM

You will now see your piano audio track:

Screen Shot 2014-02-10 at 4.18.36 AM

You can also drag this track to your arrange window by clicking on the
Piano Audio name and dragging it on to the Arrange Window:

 You can now delete the MIDI piano track if you so desire. You may also add effects, etc to your newly created piano audio track.

Signal Flow In Logic
Up to this point we have only been routing our audio to
Out 1-2 in our Logic projects. For this tutorial we are going to be working with the Mixer in Logic.

First, let’s create a new project and add four
Audio Tracks and name them as follows:

Screen Shot 2014-02-12 at 5.39.12 AM

There are two ways to bring up the mixer:
X on your computer keyboard.
Click on the
Mixer icon at the top left hand side of the Arrange Window.
 Screen Shot 2014-02-11 at 4.01.56 AM

Mixer window looks just like a mixer in the "real" world. I have set up a short project for recording a drum set with four microphones.
Screen Shot 2014-02-12 at 5.40.34 AM
You will also notice that all the audio outs are routed to
Out 1-2 or Stereo Out.

 Screen Shot 2014-02-11 at 4.04.25 AM

Adding A Bus
We are now going to change our audio output for our Drum Audio tracks. Instead of going to
Stereo Out we are going to set up a Bus to route our audio.

Make sure that you have
Aux selected in the track show window:
Screen Shot 2014-02-12 at 5.41.39 AM

You may also notice two more icons:

Screen Shot 2014-02-12 at 5.42.00 AM

The right icon allows you to view the mixer in
Narrow View (when you have a ton of tracks)

The left icon allows you to view the mixer in
Wide View when you don’t have a lot of tracks.
Let’s start with the piano. Under
I/O in the mixer track Kick on Stereo Out and select Bus 1
 Screen Shot 2014-02-11 at 4.24.20 AM
Notice that the
Stereo Out in the kick track now reads Bus 1.
Screen Shot 2014-02-11 at 4.27.37 AM

You will also notice that a
Bus 1 channel strip appears in the Mixer Window titled Aux 1 with its output set to Stereo Out.
Repeat the above process and set the
I/O to Bus 1 for all the tracks.

Screen Shot 2014-02-12 at 5.45.50 AM

Adding A New Audio Track
We now need to add an audio track so that we can route our bus tracks into the audio track.

 Select the last track so that it is highlighted (I do this to save a step) The new audio track will now be inserted directly below the
Kabasa track.
Screen Shot 2014-02-12 at 5.46.36 AM

Locate the
+ icon next to Global Tracks and click on it.
Screen Shot 2014-02-12 at 5.46.25 AM

You will now see a familiar dialog box. Enter in the following: Notice that I have selected
Bus 1 (Aux 1) for my Input.
This will make more sense soon!
Screen Shot 2014-02-12 at 6.04.55 AM
Arrange window should now look as follows:
Screen Shot 2014-02-12 at 5.49.11 AM

You may have noticed that I have recorded some audio tracks. You may want to do the same. For this tutorial I just want you to understand basic signal flow.

 By enabling
Input Monitoring, it allows us to hear the audio before it reaches the Audio Out 1-2 so that we can determine if the signal is hot enough to record or too hot so that the signal is clipping.
To view your audio signal using
Input Monitoring, click on the first Audio FX slot in your audio track.
Screen Shot 2014-02-12 at 5.54.49 AM

Metering, Level Meter, and then Stereo or Mono depending on the type of audio track you have.
Screen Shot 2014-02-12 at 5.54.35 AM
You will now see a
Level Meter for your audio 1 channel, allowing you to monitor the signal input.
Screen Shot 2014-02-12 at 5.56.33 AM

When I play my sequence I can see the
Level Meter in action:
Screen Shot 2014-02-12 at 5.56.45 AM

I strongly suggest that you insert a
Level Meter into each track so you can monitor the incoming audio signal.
This is what our
Mixer window should now look like:
Screen Shot 2014-02-12 at 6.08.25 AM

Notice that I have place the
Level Meter in my Mixer window for better monitoring of the audio signal.
Recording and Bussing Audio
We are now ready to record some audio!
If you were recording “live musicians”, you would use your level meters to view the levels and make sure that they were strong, but not clipping.
I have already recorded my mini drum section and now I want to mix it down into a single stereo track. We can do this via the bus setup that we have configured.

I am now going to label my newly created audio track
Drum Mix by double clicking on the track name in the mixer and changing the name.

 Screen Shot 2014-02-12 at 6.09.11 AM
You will now see your drum audio track in the
Mixer Window
Screen Shot 2014-02-13 at 8.29.12 AM

My goal is to make a stereo mix of my four percussion parts by bussing all the parts to a single track. To do this, first solo all the tracks that you want to bus into your
stereo mix track.

In this case I am going to solo all my percussion tracks. Now only the soloed tracks will sound. You do this by selecting the
S on the tracks:
Screen Shot 2014-02-13 at 8.32.27 AM

Notice that your audio regions are surrounded by a yellow line indicating that you are in solo mode.
Now play your sequence and check the
Level Meter. You may have to adjust the volume of the drum track using the fader on the drum track.
The picture below shows a fairly robust signal.
Once you have set your
Level, rewind your sequence to the beginning.
Make sure that the
Metronome is turned off, especially if you are recording a MIDI track as the metronome will also be recorded.
Arm the
Drum Audio Track for recording by clicking on the R in the channel strip (it should start blinking)
Screen Shot 2014-02-13 at 8.37.48 AM

Hit the
* key on your extended keyboard or click on the Record button in the Transport window to begin recording.

 Screen Shot 2014-02-13 at 8.38.25 AM
Hit the
Spacebar to stop recording and the drum audio file should now appear in your Arrange Window.

 Screen Shot 2014-02-13 at 8.37.06 AM
In the screen shot above, I have muted all the percussion tracks so that I can hear my stereo percussion mix.

This is an easy way to set up several different drum mixes that can be mixed down to a stereo track.
While this method is somewhat slower than the
Bounce method described earlier in this tutorial, you can monitor your input signal as you go. Also, remember that you can set up different bus channels so that you can record more than one audio track at a time!
