Boring But Very Useful: How to Prep A Mix In Ableton Live

One of the dullest parts of production, but one of the most important for properly finishing a track is preparing to mix it.  If and when people think of music production as a sexy and glamorous job, they are certainly not thinking of the time spent getting a track set up for a mix.  In terms of excitement this can rank up there with clipping toe nails, but like the aforementioned activity, it’s important to do it well to avoid some much bigger problems later on.

Essentially I see production and mixing as utilizing two different parts of the brain.  Production is a creative process where you want to let the ideas and inspiration flow.  Mixing, on the other hand, is a practice that is heavy on organization and more logical decision making.  This is not to say that there is no creativity in a mix – obviously there is.  There is a good reason why many producers (including myself) prefer that others mix their productions, even if they are excellent mixers, because it can often help the project to have someone else add their ears and sensibility to the music. Another way to divide the process, which I often do, is do a mix in a completely different DAW, say the production in Ableton and the mix in Logic.  This is not because of some magic sonic quality of the DAW.  Although I may get flack from the denizens of, I believe that mixing skills are 99% of the sound of the mix and maybe the DAW contributes less than 1%. After all, can the vast majority of humans (including myself) really tell what DAW a track was mixed it?  It is simply that it forces me to start with a totally different mind state.

In today’s world of laptop production and artist/producers it’s pretty common that you end up doing both the production and mixing – in the same DAW. So here are five tips to help you get your track ready to mix and make your mixing flow more easily and quickly.


The most basic part of the mix prep process is labeling every single track that is in your production.  Here’s a shot of what an organized set in Ableton live looks like:

Organized Mix

You should never leave any track looking like this track below that says ‘22 Operator’ – without a clear name:

Empty Track

If you have tracks like this, the way you label a track in Ableton live is by using Command-R and giving it a new name.  I would also strongly encourage you to color-code your tracks.  You do this by right clicking (Control-Click for you Mac users) over the name of the track:

Ableton Colors

I also like to color-code the clips in arrangement view to be the same color as the track as you can see from the shot of the organized set.   You do this by Rt-Clicking on top of the clips and the same info will pop up.


When turning a production set into a mix platform everything that’s not needed must go.  Any track that is muted should be deleted.  Also, since in Ableton the mix console is in session view, I get rid of every clip and scene.  This will help you with the CPU which we’ll talk about more in the next section.  Here’s what session view looks like in one of my mix sessions.

One of the really important things with a mix session is that you need to keep a lot of CPU available, especially if you are using external plug-ins.  (I use some fantastic external plug-ins for mixing, but more about that in other posts).  One basic way to do this is to go to the Audio Tab in Live’s Preferences and set the Buffer Size to 1024 or 2048:

High Buffer Size

The second and perhaps more important way to do this is to eliminate all of your MIDI tracks.  This serves two crucial functions.  Firstly, it saves CPU, but perhaps even more importantly, it forces you to stop producing.  Yes, it is really important that during the mix, you should not change parts unless absolutely necessary for the song and the arrangement.  Again, you do not want to remain in music creation mode while focusing on a mix and working in audio forces away from changes because they become more of a pain in the ass.  Of course, you always have the option of returning to an earlier version and flying something in if necessary, but this will take a couple of extra steps.

To turn a MIDI track into audio in Ableton Live you want to do the following:

  1. Rt click on the track name in Arrangement View and select “Freeze Track”:

Freeze Track

  1. Once you do this the track turns white.  Only then can you right click on it and select “Flatten”:

Flatten Track

  1. Once you do this, the track will turn to to an audio track as you can see by the wave forms in the clip:


Just a note here.  If you do this process, all of your instruments and effects will now disappear as they are written into the audio.  In general I believe that this is a good thing, but there are times when you want to keep some insert effects in the track so you can tweak the settings in a mix.  If that’s the case, a technique I use to preserve them is to Command-C (copy)them, Freeze and Flatten the track and then Command-V (paste) them back into the track.  This can be really useful when dealing with the hitch that you cannot Freeze and Flatten a track with a Side chained Compressor or Gate.  Just copy the device, delete it, Freeze and Flatten the track and paste it back in.


My colleague at NYU’s Clive Davis Institute of Recorded Music, the legendary mix engineer Bob Power, once told me that “A mix is a good arrangement.” As in so many things, Bob is absolutely right. What you are doing when you mix a track is making sure the production essentially tells a musical story – it rises, falls and climaxes in certain places.  Music, like film, is a time-based art and the listener waits for these moments as payoffs.  Therefore, there is absolutely no way you can truly mix a track unless you have an idea of the entire production.  One thing I do is add an arrangement track.

An arrangement track is simply a blank MIDI track that sits at the top of the production in arrangement view.  Part of the preparation to mix is mapping out the song in this track using blank MIDI clips.  To do this, simply select the bars of a section within the MIDI track and use Shift-Command M to make a MIDI clip.  Then use Command-R to rename it.

Now, of course you can do something similar with Ableton’s Locators which you will find in Ableton’s Create menu under “ Add Locator”.  I prefer the first method because I can color code the MIDI clips and that allows me to see the arrangement and sections very easily

Arrangement Track


This is one of the most important parts of a preparing a mix.  These days, many artist/producers do not have access to a perfectly tuned room and state-of-the-art speakers.  Therefore, having a reference track is one of the most important things that you can have for your mix.  A good reference track is firstly always a WAV of AIF file. Do not use a MP3 or any other compressed file.  You want to mix against the highest quality audio you can.  Secondly, pick a track in the approximate genre. You obviously don’t want to reference your house track against say Morton Subotnik’s ‘Silver Apples of the Moon.’  Thirdly, choose your references by producers rather than whether you like the song.  I consider Subotnik’s “Silver Apples of the Moon” a ground-breaking work of genius but if I was mixing a pop track, I would be referencing the hardest hitting contemporary stuff I could find since top charting pop often has fantastic production value, even if I’d rather be listening to something else in my free time.

To set up a reference track, I create an audio track below my arrangement track and simply load in my WAV/AIF file.  Often, I’ll chop it up and simply loop the heaviest 16 bars since I really don’t need to reference the synth intro or drum outro.  Other times I will use one reference for the kick and another for the voice.

The key to using a reference track is the ability to A/B it quickly with your mix.  In order to do this, you want to do a couple of things.  First, turn the volume down between -6 and -8 dB.  Any reference track will be mastered and therefore louder than your mix.  This is bad because your ears have a natural tendency to assume that louder sounds “better.”  Therefore, your mix and reference track should always be at the same volume.  Secondly, use Ableton’s Key Mapping To Set Up a Quick A/B Key.  I use Command K to enter Ableton’s key mapping function and map the period key to the track’s Solo button.  WIth that I can listen to the reference with the flick of a finger and then by hitting it again get back to my mix.

I hope this is useful as you prep your mix and I look forward to sharing some advanced mix prep techniques as well.
