Music Production

When enabled, the Elastic Time plug-in analyzes two dimensions of your audio in order to calculate the recorded performance’s tempo. It looks at the audio region’s duration in bars and beats, and it looks for transients that represent a regular periodic rhythm in the recording. In theory, if the rhythmic content of your recording is clear, with distinct transients, Elastic Time can figure out a performance’s tempo regardless of whether the audio region is trimmed to a perfect loop or not. This is really neat when it works, but it doesn’t perform miracles (nor should you expect it to, that’s not producing your own music).

Instead of relying blindly on Elastic Time to perform your beat matching (as in, crossing your fingers and hoping for the best), there are several simple steps that you can take ahead of time to prepare the audio and ensure perfect results every time. Performing this pre-processing, even though it’s a tedious task, helps to preserve the audio quality and the groove of the original performance after your tempo change.

The easiest way to demonstrate my pre-processing approach is to take you step by step through the process. This is the best way to understand not only the steps in the process but the logic behind my approach. (Try it a different way and you’ll find out just how quickly you can end up with a train wreck.) The DRM (Digital Rights Management) free stems being offered for your remixing pleasure by Radiohead, of their song “Nude”, on iTunes is perfect for this example. The stems are $0.99 each and you only really need two of the five available, the “Drum Stem” and the “Voice Stem”. But, it’s nice to have all of the stems in your session, even if you don’t use the “Bass Stem” and “Guitar Stem” they’re handy for finding the key of the original, and the “String FX Etc. Stem” contains several sounds that are perfect for a remix.

Remixing Radiohead

1. Create a new Pro Tools session and import all of the “Nude” stems. When prompted, select the import Destination as New Track with a Location of Session Start.


2. Arrange the tracks in the Edit window with the Drum Stem on top and the Voice Stem just below.


3. Mute all of the tracks except the Drum Stem. Use Tab to Transient to locate the very first downbeat in front of the vocals (approximately 1946229 samples in from the session’s start) and separate the regions.


4. Select the Edit Group, double click on the latter Drum Stem region and separate all of the regions.


5. Select the Shuffle Edit Mode and delete the first set of regions so that the downbeat of the second set of regions scoots to the beginning of the session.


6. Disable the Edit Group and using Tab to Transient find the downbeat every two bars in the Drum Stem and separate the regions. (The only region that I left as 4 bars is the drum break, having 2 bars before the break itself.) In some instances, you can make the separations every 4 bars, but with “Nude” there’s a lot of human tempo variation and every 2 bars will produce the most precise overall beat match.


7. Select the Edit Group and double click on each 2 bar Drum Stem section and separate the sections.


8. Select each 2 bar section and apply Identify Beat to generate a tempo map for each section. This will beat match and lock each 2 bar section to your session’s tempo grid. (You could use Beat Detective to generate a tempo map, but my method preserves the original performance’s groove every two bars, while simultaneously guaranteeing that the original’s downbeat is locked exactly to the grid every two bars. This way, your beat match never drifts.) At this stage, it’s also helpful to create a Click track in order to audition your tempo lock.


9. Change the Timebase selector for all of the tracks to Ticks. This will lock the regions to their relative bar and beat positions so that they stay in beat when you make your tempo change. Then, enable the Elastic Time plug-in for each track. Set the Drum Stem to Rhythmic, the Voice Stem to Monophonic, the String FX Etc. Stem to Polyphonic, the Bass Stem to Monophonic, and the Guitar Stem to Polyphonic. Give Pro Tools time to analyze the audio. (For now, leave the Elastic Time plug-in set to Real-Time Processing.)


10. In the Transport bar, disable the Conductor and enter a new tempo in the Current Tempo field, or experiment with the Manual Tempo Slider. Since the original tempo is about 42 BPM, it’s nice to bring the tempo up to about 62 BPM. At this tempo you can then record drums in double-time (124 BPM) and be at a dance tempo! (Once you decide on your remix target tempo, if your computer is running short on processing power, your can set the Elastic Time plug-in to Rendered Processing.)

Here’s what the final results sound like, using all of the stems at 62 BPM, some effect processing, and backed by Digidesign’s Strike virtual drum instrument playing in double-time at 124 BPM:
Nude – The Strike Remix (by Erik Hawk)

Do you think you’re set with one pair of professional studio monitors? If so, think again. Most home-studio owners purchase one good pair of powered reference monitors and that’s it. However, to truly hear how your music will translate to the outside world, the real world beyond the four walls of your comfy studio, you should be working on at least two sets of speakers: your main near-field monitors and a set of small, inexpensive desktop computer speakers (minimonitors). This dual monitor approach will let you hear how most listeners will be hearing your tracks—over a cheap home stereo system, a television, or computer speakers—instead of the precise, accurate, and “flat” sound of your pricey studio reference monitors.

Of course, chances are that your audio interface only has one set of monitor outputs (a pretty standard design). This begs the question, “Where do I connect another set of speakers?” The solution is to add an analog monitor control box to your system. The stereo mix coming out of your audio interface’s monitor output is then connected to this box and split (multiplied) into several monitor output paths, each of which can be sent to its own monitor destination (including headphones). Two of the most popular solutions on the market are the PreSonus Monitor Station ($400) and the Mackie Big Knob ($390). Each of these units is designed to sit on your desktop and provide ergonomic monitor control, making it easy to switch between monitors while you’re mixing without losing your “sweet spot” (the listening position between your monitors that sounds the best).

The point of near-field monitoring is to remove as much room coloration from your listening position as possible. Though it’s no less important to tune your room for better acoustics (a topic for another blog), a proper near-field setup can reduce much of the room tone that you would normally hear if you were seated farther away from your monitors, outside the sweet spot. Today, most well-designed studio reference monitors feature frequency fine-tune controls for tailoring a speaker’s response to best fit your listening environment. For example, to compensate for a room that adversely emphasizes low frequencies, you could roll off your monitor’s low-frequency response by a couple of dB. Foam speaker-isolation wedges (such as the Auralex MoPAD) are also an option and allow a monitor to be decoupled from what it sits on, preventing the speaker from transferring sound to the surface in a way that might adversely affect what you hear.

Now, for the speakers. Keep in mind that the size of the low-frequency drivers (the woofers) determines your monitors’ low-frequency output. The larger the woofer, the more bass you’ll hear in your mix. Consequently, you should stick with a 6-inch woofer or larger for your main monitors. In my opinion, the best enclosure-size-to-bass-output ratio for your dollar comes from monitors with 8-inch woofers (such as the Mackie HR824 or Event Studio Precision 8). Of course, you can add a subwoofer to augment monitors with small woofers, but for most music-production applications, having the bass in your face is preferable to having it under your seat or to the side of your workspace. By comparison, your minimonitors should have a 3- to 4-inch woofer (such as the Edirol MA-7A or M-Audio StudioPro3). And, for the sake of quality and convenience, the minimonitors should be self-powered, just like your main monitors.

How your speakers are set up is also crucial for good monitoring. For the best near-field monitoring possible, make sure that your speakers are upright and level with your head. When seated in the sweet spot between your speakers, your head and the two speakers should comprise the three points of an equilateral triangle. You can place the minimonitors just to the inside of your main monitors. Make sure that the speakers are as far away as possible from any walls to avoid potential low-frequency interaction with your room’s physical structure. Pushing your speakers against the wall or shoving them in a corner is never a good idea. Remove any impediments that might interfere with a clear line of sound from the speakers to your ears (such as plastic figurines and stuffed animals—really, I’ve seen it done). And, watch out for possible reflective surfaces just beneath the monitors (such as a large mixer or laminated tabletop) that may cause high-frequency reflections to bounce off and sully your sweet spot.

Between your main monitors, a pair of minimonitors, and a studio-quality pair of headphones (such as the Sony MDR-7509 or Ultrasone Proline 750), you can construct a clear picture of how your mix will sound in the real world without ever leaving your studio. Plus, with a good monitor controller you’ll never need to move from your sweet spot to switch monitors. Now, with all of this control at your fingertips, the only trick is to remember to get up and use the restroom every so often. Though, seriously, if that’s not inspiration enough, many an award winning mix engineer has been known to walk outside the studio, and down the hall, in order to hear how their mix sounds from a completely different perspective—for real, it really does work.

A mashup (AKA bootleg) is taking two songs and beat-matching them together to create a new blended mix of both songs. For example, the classic mashup of Kylie Minogue’s “Can’t Get You Out of My Head” and New Order’s “Blue Monday.” It’s often done using full stereo mixes (with vocals), or, alternately, an a cappella and a stereo mix (possibly an instrumental). To hear a variety of well crafted mashups, check out Party Ben.

Mashups became such a hit on the dance-floor that some producers (such as Richard X) went on to remake parts of the original songs in order to clear the entire mashup for commercial release. For example, the 2002 UK hit by the Sugababes, a combination of the lyrics from Adina Howard’s “Freak Like Me” and the music of Gary Numan’s “Are Friends Electric?”

The point behind my little history lesson is, you don’t always have to play a traditional instrument, or even record a track, in order to be wonderfully creative with music. I have the privilege of working with music production students at all levels of experience, some are seasoned musicians while others are just starting piano lessons. Obviously, for our production project in class, I expect students to create their own tracks, one way or another. It’s a snap for experienced players to record a performance, but a serious challenge for students just beginning an instrument to record something decent. As an alternative, I encourage the use of MIDI files, a cappella mixes, and sampling. (For educational purposes only, of course.) These resources can provide a signal and a musical performance with which to practice your production chops whether you play an instrument or not.

However, if you have never worked with samples or imported a MIDI file, taking advantage of these resources can be intimidating. One of the best ways I know to explain the whole process is to show you in a song. So, without playing a darn thing, just using my ears and production skills, I produced a mashup in Reason 4 using an a cappella, a MIDI file of a cover tune, and a sample of the original tune — all items I found for free on the Web. This mashup features Tone-Loc’s “Funky Cold Medina” and Kraftwerk’s “The Model.”

You can download the Reason 4 song file below (it’s about 8 MB) and explore the production, from its samples to its mix. To download an MP3 of the mashup, visit my myspace page.

There’s a lot that goes into producing a convincing drum track, especially when your drummer is a software sampler (such as Reason’s Redrum and NN-XT, Native Instrument’s Battery, or MOTU’s MachFive). Indeed, the shear number of techniques employed to create a great drum track would keep me writing blogs for months to come. But, rather than go on and on about how to produce realistic sounding drums, let’s cut to the chase and look at how it’s done in a Reason song file.

Using Reason 4, I’ve cooked up a song file that demonstrates how to produce and mix realistic sounding drums. I’m using only samples found in Reason’s Factory Sound Bank and Redrum as the sample playback device. You can do much more with the NN-XT in terms of the shear number of samples and velocity zoning. However, since most beginners reach for Redrum first, I decided to hold off on the NN-XT. The mix is not mastered (there’s no Mastering Combinator or Maximizer in the rack) so that you can see and hear how your drum levels should be hitting before mastering. (Mastering should be used to make a great mix sound awesome. Unfortunately, mastering is too often used to make a poor mix sound passable. But, that’s a subject for another blog.)

If you have Reason 4, you can open up this song file and explore the connections and settings. Of course, your drum tones and compression levels will vary with each individual mix, in relation to the other instruments in your song. For example, you might want your snare to have less compression on the initial attack of its waveform, for greater snap, or your kick to exhibit more mid frequency pop around 8 kHz. Fine adjustments such as these are easily accomplished when your devices are properly set up and routed, as they are in this song file. Alternately, if your drums aren’t properly routed, fine tuning your drum mix can be an exercise in frustration. Many of the techniques employed in this drum mix are the sorts of things that I teach in my Berkleemusic course, Producing Music with Reason.

Here’s a list of the production techniques used to produce this drum track:

· Compression and parametric EQ inserts
· Parallel compression
· Group effects
· Individual outputs
· Gesture sampling
· Proper levels and gain structure
· MIDI performance sample (a drum sequence created by a real drummer)

Turn your speakers up and have fun exploring this song file!

During this season of gift giving and gear lust I would like to remind us all (myself included) that it’s not the gear that makes great music. You’re the one that writes, plays, and produces the music, not the equipment. In fact, I bet, if you put your mind to it, you could write a cool beat with a kazoo and some cardboard boxes, and nary an AC outlet in site. But, instead, you’ve embraced high-tech music gear as your recording instrument of choice.

Sure, quality recording products give you the tools to make excellent sounding recordings. Assuming, of course, that you have some basic knowledge of music and recording engineering. However, ultimately, it’s the quality of the song that matters the most, because no matter how well a bad song is produced, it’s still a bad song. By comparison, a well crafted song that is also well produced has the potential to be a hit.

So, when purchasing your next amazing high-tech music making gizmo, keep in mind that it will not be able to magically make your songs better. If you already own all the equipment to record your tracks (for example, a computer, DAW software, audio interface, MIDI controller, and quality studio monitors), and you imagine that this next piece of gear will make your productions that much better, think twice before you spend your hard earned cash. Sometimes, it’s not a lack of gear that’s holding you back, but a lack of knowledge about how to use the gear you already have to its absolute fullest potential.

Fortunately, there is today a wealth of resources available to help you improve your craft, on both technical and creative fronts. If you can play an instrument and have a decent grasp of music theory and notation, you’re ready to jump right into production classes (such as Pro Tools 101 and Producing Music with Reason). If you’re shaky on the fundamentals of music and have not mastered an instrument, than you should start at square one and study music theory and an instrument (such as Music Theory 101 and Berklee Keyboard Method). If you’re not currently in a position to take Berkleemusic online courses, to start you on your way, treat yourself to a couple of books from Berklee Press (such as Instant Bass and Producing in the Home Studio with Pro Tools).

Lots of enthusiasm for making music is excellent, and most certainly a necessary ingredient to being successful in this industry. However, along with all that enthusiasm you’ll also need to know which end of a microphone boom to sing into. (See the YouTube video below.)

Happy Holidays! Have a safe and musical New Year!

Of course, just because you don’t understand compression doesn’t mean that you’re mentally challenged. As a rule, the compressor, and how it controls a signal’s dynamics, is one of the more challenging processors to grasp. Learning how to effectively apply compression in your mix can take a significant amount of study time, patience, and good old fashioned experience.

Now, I could explain what each parameter of a compressor does and how it affects the signal. I could even give you some compression presets to get you started. But, this approach would be old hat and does nothing to help you actively hear compression and how each of its components work. You see, without the ability to hear in your mind how compression colors a signal, and to then know which parameters on a compressor to reach for in order to achieve your sound, you’re just fumbling blindly.

The skill necessary to properly operate a compressor is comparable to the ability you developed as a toddler to recognize and apply colors. You learned to visualize what color you wanted to apply to the flower in your coloring book, and you learned which color to reach for in your box of crayons to achieve your objective. The trick with compression, as with any type of processing or synthesis used in music production and sound design, is to know, instinctively, which parameters to reach for in order to create the sound you’re hearing in your head. It’s a deceptively simple process because it’s so easy to quantify, but as we all know from experience, it’s tough to put into practice.

With all this in mind, I’ve cooked up an interactive compression lesson to help you better hear compression, and learn to associate compression colors with specific compressor parameters. It’s a Reason song file full of MClass Compressors, with each Compressor adjusted slightly differently, but applied to the same snare drum signal. Each compressor’s label reflects its parameter change (such as “More Attack” or “Less Attack”), so that you can easily identify the Compressor’s parameter that you’re hearing, in relation to a base compression setting (the “Basic Compression” device). And, since a sound is rarely heard on its own, but, instead, always with accompaniment, I’ve included the rest of the drum mix as a stereo stem on Channel 12 of the mixer.

Here’s How You Work It
Press Play to start the drum pattern, then, to hear each compression setting, solo each snare drum signal on the mixer (Channels 1 to 10), one channel at a time. Leave the drum mix on Channel 12 in solo mode so that you can hear how the different compression settings make the snare “sit” in the drum mix.

Many of the changes to the snare drum’s sound are subtle and a challenge to hear, especially if you’re new to this sort of critical listening. Accurate monitors are also key in being able to hear the differences in the drum’s sound. So, if you’re not hearing the differences right out of the gate, not to worry, below is a description of what you’re listening for in each compression setting.

Channel 1: “No Compression”
This is the snare drum dry, with no compression processing.
Channel 2: “Basic Compression”
This is a decent snare drum compression setting. It is the starting point from which a single parameter is changed in the following Compressors. For example, on the “More Attack” Compressor, all the parameters are identical to the “Basic Compression” settings except the Attack parameter.
Channel 3: “Less Threshold”
Increasing the Threshold means that less of the incoming signal will be compressed. Another way of putting it is that the threshold at which the signal will begin being compressed is higher.
Channel 4: “More Threshold”
Decreasing the Threshold means that more of the incoming signal will be compressed. Another way of putting it is that the threshold at which the signal will begin being compressed is lower.
Channel 5: “Less Ratio”
There’s no easy way to explain the compression ratio. It’s math, there’s no getting around it. Ratio sets the amount of input signal necessary to cause a 1 dB increase in output signal. For example, with a ratio of 4:1, an 8 dB increase in input will produce a 2 dB increase in the output. So, less Ratio means that an increase in input signal will sound louder at the output, less compressed compared to the original “Basic Compression” setting.
Channel 6: “More Ratio”
With more compression ratio applied, more input signal will be required to produce a 1 dB increase in output signal. Consequently, the output signal will sound more compressed when compared to the original “Basic Compression” setting. At high compression ratios, limiting occurs, where, at the most extreme settings, the output level stops increasing no matter how loud the input level becomes (referred to as “brickwall” limiting). In situations where the output level is very low in volume, you can use the Compressor’s Output Gain control to turn it up.
Channel 7: “Less Attack”
The Attack parameter sets how quickly the compression will begin. So, turning the Attack up means that less of the signal’s initial transient (the very beginning of its waveform) will be compressed. This is good if you want to retain the crack and pop of the waveform’s start.
Channel 8: “More Attack”
Turning the Attack down means that more of the signal’s initial transient will be compressed. This is good if you want to diminish the crack and pop of a waveform’s start.
Channel 9: “Less Release”
The Release parameter determines how long it will take for the compression effect to fade out. So, less Release equals a shorter release time and the signal’s waveform will be compressed for a very limited duration. This is good if you want to retain the natural decay of a waveform.
Channel 10: “More Release”
Turning the Release up means that the time it takes for the compression effect to fade out will be longer. This is good if you want to compress the natural decay of a waveform, like increasing the volume as the signal fades out.

After you’ve listened carefully to each compression setting, try describing the changes in the sound that you hear. This will connect what you’re hearing to a concrete idea in your mind. And, ultimately, help you to associate a compression color with a specific compression parameter. Once you master hearing what each compression parameter can do on its own, then you will begin to hear how all of the compression settings work together to create a variety of compression effects and sonic colorations.

Here’s the Reason song file. Remember to press Play before you begin soloing each snare drum signal, and only audition one snare signal at a time.

It seems like the Pro Tools Accelerated Videos (http://www.digidesign.com/accelerated) are often overlooked as an educational resource. Sure, they’re clearly for promotional purposes, extolling the virtues of Pro Tools. But, at the same time, they are an excellent overview of Pro Tools centered music production techniques and features, both new and old. The videos aren’t nearly as in-depth as our twelve week courses here at Berkleemusic, but if what you need is a quick blast of information, an overview of a feature or technique, the Pro Tools Accelerated Videos are just perfect.

The Pro Tools Accelerated Videos can also be seen on YouTube. Here’s one on using Reason Adapted with Pro Tools and setting up the ReWire connections:
