By Gazillion Industries, who make BEEFY. --- Roar is the biggest saturation device in Live, and it can be pointed at most jobs. Which is why the question comes up: if it already does everything, what is a second box for? Roar covers most of what a drum bus needs, so the first move is to use it better rather than stack something on top of it. Add a second stage only when that stage does a different job: Roar shaping the body in parallel, then something simple catching the peaks it leaves behind, or the reverse. Two devices doing the same job at half strength each sound worse than one doing it properly, because the second one distorts the first one's harmonics. Level-match before judging any of it. Most stacked chains get kept because they are louder. ## The short version - **Roar alone**: usually enough; learn its routing before adding anything - **Add a stage when**: it has a job the first one is not doing - **Series**: stage two distorts stage one's harmonics as well as the music - **Parallel**: keeps the dry transient; lets you push the wet path harder - **Before judging**: match the output to bypass with Utility - **The trap**: two soft saturators at half strength read as blurry, not rich - **Peaks**: a clipping stage last, doing only that ## What Roar is already doing Roar is a chain pretending to be one device. It has more than one shaper stage, a set of routing modes that put those stages in series, in parallel, split across frequency bands or across mid and side, a filter and tone section, a compressor, a noise generator, a feedback path and a modulation matrix that can move any of it. Told to, it can be a gentle glue stage, a bandsplit distortion, a mid-only color stage, or a mess. Which means most "I need another saturator" moments are routing questions. Harsh kit: multiband keeps the drive off the top. Dying transient: parallel gives it back. Smearing low end: mid/side leaves the center alone. None of that needs a second device, and all of it is easier to judge, because there is one thing to undo. Where Roar stops is legibility. When a preset is doing five things at once, you cannot tell which one you liked, and the next preset changes all five. That is a real reason to reach for something smaller, and it is a better reason than tone. ## What each Live device is actually good at Live ships more saturation than most people ever use. The devices are not interchangeable. - **Saturator**: one curve at a time, cheap, predictable; the reference stage - **Drum Buss**: drive, transient shaping and a tuned low boost, built for a kit - **Roar**: everything above plus routing, modulation and feedback - **Dynamic Tube**: small grit that follows the envelope; narrow range - **Overdrive**: band-limited, pedal-flavored, obvious fast - **Amp**: heavy mid-forward color; good on a loop, rough on a full kit - **Utility**: no saturation at all, and the most useful device in the list **Saturator** is the one to learn first. One curve, a drive control, a tone section, a dry/wet. It colors the whole signal evenly and has no idea what a transient is, which sounds like a limitation until you want a stage whose behavior you can predict. Soft Sine for weight, Analog Clip when the peaks should go too. **Drum Buss** is the only one on the list designed around a kit rather than around a waveform. Drive and Crunch do the distortion, Transients gives back the attack the drive just shortened, Boom adds a tuned resonance under the kick, and Damp keeps the top from coming with it. It stops where its voicing stops: there is one flavor, and on a busy kit the Boom can start playing a note of its own. **Dynamic Tube** earns its place when the grit should follow the playing. Its bias control ties the amount of distortion to the incoming level, so ghost notes stay clean and accents get dirty. Pushed, it goes woolly in the low mids. **Overdrive** and **Amp** are color devices rather than bus devices. Both change the midrange balance of whatever goes through them, which is useful on a single loop and expensive on a kit you are trying to keep clear. ## When a second stage helps, and when it is just more of the same The useful test is whether the new device has a job the old one is not doing. Three that pass: - **Color, then peaks.** Roar makes the kit denser and hotter; something after it takes the kick and snare spikes off so the group fits under the mix bus. Two different jobs, and the second one has a clear success condition. - **Parallel body, series glue.** A hard-driven parallel path adds weight under the kit, then a light stage across the whole group ties the blend together. The parallel path can be pushed far past anything you would accept in series, because the dry signal still carries the attack. - **Different frequency, different device.** One stage on the low end, one across the top. Roar does this by itself in multiband mode, which is usually the better answer. Three that fail: two drives set halfway because neither sounded right on its own; a second saturator added because the first one did not get loud enough; and anything added while the chain is louder than bypass. The last one is the most common by a distance. The background on what these devices are all doing to the waveform is in [saturation vs distortion](https://gazillionindustries.com/saturation-vs-distortion/), and the drum-specific version is in [how to saturate drums](https://gazillionindustries.com/how-to-saturate-drums/). ## Series or parallel In series, every device hears what the last one made. A saturator fed a signal that already carries a strong second harmonic does not just add more second harmonic to the fundamental: it generates harmonics of that harmonic, and sum and difference tones between the two. Those land at frequencies unrelated to the drum, they pile up in the upper mids where the ear is least forgiving, and they are why a chain of mild stages can sound worse than a single strong one. Each stage also shortens the attack, and the attack runs out. In parallel, the dry path is untouched, so the transient survives whatever you do to the wet path. That changes how hard you can push: a parallel stage sitting well under the dry path can be driven to the point of obvious distortion and still read as weight rather than as an effect. Live gives you three ways to do it. An Audio Effect Rack with two chains and the chain volume as the blend is tidiest, because it saves as one preset. A return track works and stays aligned, since Live compensates for device latency across tracks. A duplicated group is the most flexible and the easiest to lose track of. One caution: anything with filtering in it shifts phase, and a phase-shifted copy blended against a dry one can hollow out the low end. Roar's multiband mode, Amp, Overdrive and any EQ inside the parallel chain all qualify. Check the blend in mono and listen to the kick, not the kit. ## Level-match before you judge any of it Saturation raises the average level much more than the peak, which is the whole point of it and also why an untested saturated bus wins every comparison it is in. A drive stage that leaves the peak meter where it was has still raised the loudness, and a fraction of a decibel is enough to make anything sound better. - Put Utility at the end of the chain. - Play a loud section, note the loudness with the chain bypassed. - Engage it, pull Utility's gain down until the two read the same. - Now switch between them and listen to the hats and the snare tail rather than to the size. - If it still wins at matched level, keep it. Half the stacked chains in the world do not survive step 4. The ones that do are the ones worth building. ## Why two saturators that do the same thing sound worse Take a single drum hit. A soft curve rounds its peak and adds harmonics that decay as they climb, so the hit gets denser and slightly shorter. Feed that into a second soft curve and three things happen at once. The harmonics the first stage made become inputs to the second, so upper-mid energy stops growing in proportion and starts compounding. The intermodulation between the new harmonics and the original content fills in the space between them, which is heard as haze rather than as brightness. And the attack, already blunted once, gets blunted again, so the kit moves backward in the mix at exactly the moment you were trying to push it forward. Aliasing stacks the same way. Any nonlinear stage can generate content above what the sample rate carries, which folds back down at frequencies unrelated to the music, and the next stage distorts the folded-back content too. If a device offers oversampling, it is worth the CPU on a kit with cymbals in it. The fix is not subtle. Give each stage one job and set it so it clearly does that job on its own. A chain where every stage does a little is a chain where nothing can be adjusted, because every control changes everything after it. ## A chain that holds up - Group the drums and trim into the group, so the chain always sees a consistent level. - Pick one color stage and set it in context, not in solo. Solo flatters distortion. - If the top of the kit is getting harsh before the body is dense enough, move some of the job: multiband, or a parallel path, or less drive and a peak stage after it. - Put the peak stage last and give it only that job. Soft clipping is the usual choice here; the mechanism is in [soft clipping explained](https://gazillionindustries.com/soft-clipping-explained/). - Utility at the end, matched to bypass. Decide. ## Questions people ask ### Is Roar enough on its own for a drum bus? Usually, yes. Roar has multiple shaper stages plus serial, parallel, multiband and mid/side routing, so most reasons for adding a second saturator are answered by changing its routing instead. The common exception is a dedicated peak stage after it, which is a different job rather than more of the same one. ### Should Saturator go before or after Roar? Before, if you want Roar to react to an already-shaped signal, which makes Roar's compressor and feedback behave differently. After, if the job is catching peaks, in which case set Saturator to Analog Clip and use it for that alone. What does not work is both set to a mild drive, because each one is then distorting the other's harmonics. ### Drum Buss or Roar on the drum bus? Drum Buss when you want the kit-specific tools: transient shaping and a tuned low boost alongside the drive. Roar when you want control over where the drive lands. Running both is a stacking problem unless Drum Buss is there for Transients and Boom with its Drive near zero, which is a legitimate use of it. ### Does stacking saturators make a drum bus louder? It raises the average level, which is heard as louder, and that is why stacked chains feel like an improvement before they are level-matched. Whether it is still an improvement at matched loudness is a separate question, and often the answer is no. ### Why does my drum bus sound duller after adding saturation? Each nonlinear stage shortens the attack a little. Two or three of them in series shorten it a lot, and a kit whose transients are gone reads as distant even though it measures louder. Back the drive off, or move part of the work to a parallel path where the dry transient survives. ### How do I level-match in Ableton? Put Utility last in the chain, bypass everything above it, note the loudness on a loud section, then engage the chain and pull Utility's gain down until the two match. Compare after that. Matching peak meters is not the same thing, because saturation moves the average and the peak by different amounts. ### Does parallel saturation cause phase problems? Only when the wet path contains filtering, which shifts phase and can hollow the low end when it is blended back. Plain waveshaping stages are sample-aligned and safe, and Live compensates for device latency across tracks, so a return-track parallel path stays in time. Check the blend in mono either way. ## What BEEFY does here BEEFY is our saturation and loudness plugin, tuned by ear. One big **BEEF** control, and a **SOFT CLIP** stage that is on when it opens. On a bus that already has Roar on it, [BEEFY](https://gazillionindustries.com/beefy.html) is the stage after: weight, then a ceiling, set with one hand. Most drum buses are one device away from being finished, and one device past it. --- ## About BEEFY BEEFY — saturation and loudness plugin for Mac and Windows.
