An EQ band that only works when it needs to. Pick a real trance problem — kick fighting the bass, a lead that spikes on certain notes, a clap that rings — and watch the band duck and let go against the static cut a normal EQ would leave on all the time. Ableton ships no dynamic EQ, so there are three ways to build one at the bottom.
Everything the tool above teaches, written out. What each control on a dynamic EQ band does, and six specific problems in a peak-time trance mix that a dynamic band solves better than a static cut.
What each control does on a dynamic EQ band, and how to find the right setting rather than guess at it.
Where the band sits. Everything else is relative to this — get it wrong and no amount of Range or Q will fix the right problem.
How to find it: The reliable way to find it: make a narrow boost, sweep until the problem gets obviously worse, then turn the boost into a cut without moving the frequency.
How wide the band is. Low Q is a broad tonal lean; high Q is a surgical notch.
How to find it: Rule of thumb: resonances want narrow, tonal problems want wide. If you need Q above about 8 you are probably chasing something that should be fixed at the source.
How far the band is allowed to move once triggered. This is the ceiling on the effect, not a fixed cut — the band only reaches it when the trigger is well past the threshold.
How to find it: Almost always less than you think. Three to five dB does most real work. If you need more than about 8 dB, the arrangement or the sound choice is the actual problem.
The level the trigger has to cross before the band moves at all. Below it the band is completely flat and your sound is untouched.
How to find it: Set it so the band is working on the problem moments only. Watch the meter: if the gain reduction never returns to zero, the threshold is too low and you have just built an expensive static EQ.
How fast the band moves once the threshold is crossed. Fast catches transients; slow lets the front of the sound through before ducking.
How to find it: For anything triggered by a kick, fast — you are trying to catch a transient that is over in milliseconds. For sustained sources like pads, slow it right down or it flutters.
How long the band takes to return to flat after the trigger falls back below the threshold.
How to find it: Tempo matters more than people expect. At 140 BPM a beat is about 428 ms, so a release past ~150 ms on a kick-triggered band is still holding when the next musical event arrives.
The problems a dynamic EQ solves better than a static cut or a full-band sidechain, with a starting band for each.
The most common low-end problem in peak-time trance, and the one most people solve with too blunt a tool. Sidechain the whole bass and you duck its mids and body as well, when only the bottom was ever in the kick's way. The bass goes hollow every beat and the mix starts to breathe in a way you did not ask for.
A band at 60–90 Hz keyed off the kick pulls down only the range that actually clashes. Everything above stays put, so the bass keeps its weight and character right through the kick hit.
What to listen for: Solo kick and bass. You want to hear kick then bass as two separate events, not one continuous rumble. If the bass still smears into the kick, go deeper on Range before you go wider on Q.
What to watch out for: If the bass sounds like it is pumping, your Release is too long — it is still holding the cut when the bass needs to come back. At 140 BPM you have roughly 428 ms a beat, so anything past ~150 ms starts eating the note.
Lower and narrower than the bass case. The sub and the kick fundamental are often within a few Hz of each other, and when they overlap they sum into a boom that reads loud on a meter and mushy in a club.
A tight band right on the kick's fundamental, keyed off the kick, gives the transient its own window without thinning the sub everywhere else. Many producers do this with a permanent notch — that works, but it costs you sub weight on every beat where the kick is not even playing.
What to listen for: Listen for the kick's attack surviving. If the front of the kick is still swallowed, the problem may be timing rather than level — check the Attack is fast enough to catch the transient.
What to watch out for: Go too narrow and too deep here and you carve an audible hole. The sub should still feel continuous between kicks; you are making room, not removing a note.
Every supersaw has one. A frequency that behaves for most of the riff and then spikes viciously on a handful of notes, usually near the top of the phrase. Because it only misbehaves occasionally, a static cut is a bad trade — you dull the entire lead for all eight bars to fix the two that hurt.
A narrow band on internal trigger sits out of the way until that note arrives, takes the top off it, then releases. The lead keeps its brightness everywhere else.
What to listen for: Sweep a narrow boost first to find it, then flip to a cut at the same spot. The frequency you are hunting usually sits between 2 and 5 kHz and will make you wince when you land on it.
What to watch out for: This is the one case where high Q is right. If you find yourself widening Q to catch it, you have probably found a tone problem rather than a resonance — that belongs on the synth, not the EQ.
Sampled claps and snares almost always carry a boxy resonance somewhere around 300–600 Hz. At low level it reads as body and you want it. On the loud hits it rings and clutters the exact region your bass and low mids are trying to occupy.
Dynamic here keeps the body on the quieter hits and only tames the ring when it actually rings. A static cut takes the body away permanently and the clap ends up thin.
What to listen for: Play the clap against the bass, not soloed. Box is much easier to hear in context — soloed it just sounds like character.
What to watch out for: Short Release matters. A clap is a fast event; if the band is still holding 200 ms later it will duck whatever comes next.
The mix sounds full in the breakdown and cluttered in the drop, and the usual reason is that the pads and the lead are both occupying the upper mids. Turning the pads down works but costs you the width and depth that made the breakdown good.
A wide, shallow band on the pads keyed off the lead lets the pads stay big and only steps back where the lead needs the room, exactly when the lead is playing.
What to listen for: You should not be able to hear this working. If you can hear the pads dipping, either Range is too deep or Q is too narrow. Three dB across a wide band is plenty.
What to watch out for: Slower Attack and Release than the drum cases — pads are sustained, so fast timing makes them flutter. Think of it as a slow lean rather than a duck.
Open hats and rides tend to have a spike in the 6–9 kHz region that only bites on the accented hits. Across a long DJ set that is the frequency that causes listening fatigue, and it is why a mix that measures fine can still feel tiring at club volume.
A dynamic band takes the edge off the loud hits and leaves the quiet ones alone, so the hats keep their air and stop stabbing.
What to listen for: Check this at higher volume than you would normally mix at, briefly. Harshness scales with level — at low volume it barely exists, which is how it survives to the master.
What to watch out for: Do not confuse harshness with brightness. If the whole top end is too much, that is a shelf and a level decision. Dynamic is for the spike inside it.
