Roar in Ableton Live 12, explained

Roar is a saturation and coloration device, new in Live 12, with up to three processing stages, seven routing modes and its own modulation matrix and feedback loop. It's built for far more than distortion: the same device works as a targeted EQ, a harmonic exciter, a stereo widener and a self-resonating feedback effect. Roar ships in Live 12 Suite only, and picked up MIDI sidechain, external-audio sidechain, a Delay routing mode and a new filter type in the Live 12.2 update.

This guide covers Roar's layout and routing modes, then walks through five practical uses from the video this guide is based on: EQ-style saturation, low-end cleanup, drum width, an 808 preset, and a vocal chain.

What you need

Like Meld, Roar's device browser entry simply doesn't appear outside Suite — there's no way to unlock it short of upgrading.

Roar's routing modes

Roar processes signal through up to two Gain Stages, and the Routing Mode you pick determines how those stages combine:

• Single — one gain stage only.
• Serial — two stages in sequence; Blend crossfades between Stage 1 alone and both stages combined.
• Parallel — two independent stages processing the same input; Blend crossfades between them. Good for combining two very different Shaper Types.
• Multi Band — splits the signal into Low, Mid and High bands via two crossover filters, each processed independently. This is what turns Roar into a saturation-based EQ.
• Mid Side — processes the mono (mid) and stereo (side) content independently, for width without a dedicated stereo imager.
• Feedback — feeds Roar's output back into its own input, for ringing, delay-like or self-oscillating textures.
• Delay — the second stage processes a delayed copy of the first stage's output, for single slapback repeats or, with feedback engaged, longer trailing repeats. Added in Live 12.2.

Each Gain Stage has its own Shaper Amount, Shaper Bias and Filter Frequency, plus a Shaper Type (12 options, including Soft Sine, Digital Clip, Bit Crusher, Tube Preamp, the Half/Full Wave Rectifiers, Fractal, Tri Fold, Noise Injection and Shards) and a Filter Type (9 options: LP, BP, HP, Notch, Peak, Morph, Comb, Resampling and Dispersion — Dispersion also arrived in 12.2).

Using Roar as a saturation-based EQ

The video's first use has nothing to do with obvious distortion:

1. Switch Routing to Multi Band.
2. Set the crossover points between Low/Mid and Mid/High to isolate the frequency range you want to shape.
3. Solo the band you're working on using its Stage toggle.
4. Raise Shaper Amount on that band only. At low Amount settings you need a lot of Drive to hear distortion; at high Amount settings the band saturates even at low input levels — so a small Amount increase on just the low band adds warmth without touching the mids or highs.
5. Pick a Shaper Type. Tube Preamp gives a smooth, analog-leaning result that stays musical even pushed hard.

The same Multi Band setup works in reverse for cleanup: turn a band's Stage toggle off entirely (for example, the Low band) to filter out mud without adding a separate EQ device.

Sound design with the Matrix

Roar's Mod Sources tab has four modulation sources — LFO 1, LFO 2, Env (an envelope follower driven by the input signal) and Noise — and its Matrix tab routes any of them onto any parameter. A simple example: set LFO 1 to a sine wave at a tempo-synced rate, open the Matrix, and drag LFO 1 onto Filter Frequency for a rhythmic filter movement on a pad or synth, without reaching for a separate LFO device.

The Env source is particularly useful for reactive processing — for example, following a snare in a drum bus and using it to pump Roar's Dry/Wet or Shaper Amount only when the snare hits.

Widening and brightening drums

Two routing modes do most of the work here:

• Parallel, with Noise Injection on Stage 1 and Shards on Stage 2, adds brightness and grit that a straight EQ boost can't — raising harmonic content rather than just gain in a frequency range. Blend the two stages and pull the overall Dry/Wet down to taste.
• Mid Side, with Noise Injection on the Sides stage and Shards on the Mid stage, widens a clap or hat group by adding stereo-only harmonic content, instead of using a dedicated stereo imager.

For a snare that needs to cut through a mix, Multi Band with the High band's crossover raised (for example from 4 kHz to 6 kHz) and Shaper Amount pushed on that band works like an exciter: it adds real harmonic content above the crossover point rather than just boosting existing highs with an EQ.

An 808 preset: Parallel plus a Rack, not Dry/Wet

For heavily processed low end, Parallel mode with Noise Injection on Stage 1 and Tube Preamp on Stage 2 gives two very different flavors of distortion blended together. Rather than relying on Roar's own Dry/Wet control, group Roar in an Audio Effect Rack next to an unprocessed dry chain, and set each chain's level independently in the Rack. It's more setup than a Dry/Wet knob, but it keeps the distorted and dry signals as separately mixable chains instead of one blended knob.

Feedback mode and a vocal chain

Feedback routing sends Roar's output back into its own input, which behaves like guitar amp feedback: the Feedback knob (in the dedicated Feedback section) controls how much signal recirculates, and five feedback modes — Time, Synced, Triplet, Dotted and Note — set how that feedback is clocked. Note mode tunes the feedback to a specific pitch, and since Live 12.2 it can follow an incoming MIDI note instead of a fixed pitch.

On a vocal, Roar works as a lightweight channel strip: a Tube Preamp shaper stage emulates analog warmth, the per-band filters double as a high-pass to clean up the low end pre-distortion, and Roar's own Compression Amount (in the Global section) can stand in for a separate compressor plugin. For something harsher on a lead hook line, swap Tube Preamp for Tri Fold, a triangular wavefolder that adds far more high-end harmonics.

What Live 12.2 added to Roar

If a Roar preset or tutorial looks different from what you see, it's likely a 12.2-era feature. Released 2025-06-11, Live 12.2 added:

• The Delay routing mode
• The Dispersion filter type
• External audio sidechain for the envelope follower, so Roar's Env modulation source can react to a different track instead of only its own input
• MIDI sidechain, so Roar's Note feedback mode can be pitched from incoming MIDI notes instead of a fixed frequency

All of these are documented in the Roar chapter of the Live 12 manual alongside the rest of Roar's parameters — this guide already reflects the 12.2 device.

Frequently asked questions

Is Roar available in Ableton Live Standard?

No. Roar ships in Live 12 Suite only. It isn't available in Intro or Standard.

What does Roar's Multi Band routing mode do?

It splits the input into Low, Mid and High bands using two crossover filters, and each band gets its own gain stage with independent Shaper and Filter settings. It's the routing mode to reach for when using Roar as a targeted, saturation-based EQ rather than an obvious distortion effect.

Can Roar be used as an EQ instead of a distortion effect?

Yes. In Multi Band mode, raising Shaper Amount on a single band adds harmonic saturation and perceived brightness or warmth to just that frequency range, without an audible "distorted" character if the Amount is kept low. Turning a band's Stage off entirely also works as a clean-up filter.

What's new in Roar since Live 12.2?

The Delay routing mode, the Dispersion filter type, external audio sidechain for the envelope follower, and MIDI sidechain for the Note feedback mode — all added in the Live 12.2 update, released 2025-06-11.

How many routing modes does Roar have?

Seven: Single, Serial, Parallel, Multi Band, Mid Side, Feedback and Delay.

What does Roar's Feedback mode do?

It routes Roar's output back into its own input, producing ringing, delay-like or self-oscillating textures. The Feedback Amount knob controls how much signal recirculates, and a built-in compressor in the feedback loop keeps loud signals from runaway feedback.

Does Roar have its own compressor?

Yes, in the Global section. The Compression Amount knob applies compression to Roar's output — and, because it sits before the feedback loop, to the signal being fed back into the device too.
