What FX Chains Are & Why They’re Important

Before we get into how exactly you can create the most beneficial FX chains with Sound Doctor, let’s just quickly recap what FX chains are for.

And how they can seriously enhance your tracks too.

FX chains are groups of insert effects lined up one after another on your audio track.

Think of it like stacking different layers of effects (like EQ, compression, saturation, delay, and reverb) to shape and improve your track’s overall sound. 

For example, say you’ve got a vocal track that sounds flat and boring…

Just add an FX chain preset with an EQ to cut out unwanted frequencies, a compressor to even out the dynamics, some saturation for warmth, and then a touch of reverb and delay for depth. 

Instantly, your vocal will sound epic, polished, and ready for release. 

Besides how they operate, the order you choose to place these effects in your FX chains is key as well. 

For example, if you put your EQ before your compressor, you’re shaping the audio before you control the dynamics, which gives you way more clarity and punch. 

On the flip side, if you place your compressor first and then EQ after, you’re compressing the raw, unfiltered audio signal.

This will give you a much smoother, more glued-together sound 一 perfect for buses or master tracks where cohesion is everything.

Another quick example: imagine your lead synth sounds thin and lifeless. 

You could drop in a stereo chorus set to around 35% depth first to widen the image, then follow it with tape saturation (about 20% drive) to add warmth/harmonic richness.

It’ll instantly transform your synth into a fuller, more powerful presence in your mix.

Bottom line, knowing how to properly set, adjust, and apply FX chains is a game changer in the production world, which we’ll break down today.

It can literally be the difference between amateur-sounding tracks and professional-quality audio, so you’ll want to pay close attention.

Sound Doctor by Unison Audio is honestly one of the best plugins around when it comes to quickly creating epic FX chains for your tracks. 

And believe me, I’m not just being biased; it’s freakin’ legendary.

It comes with 25 super high-quality insert effects built right in 一 everything from reverb, delay, chorus, and flanger, to powerful EQ, compression, and saturation. 

Plus each one has tweakable parameters, so you can easily customize your sound exactly how you want it. 

Sound Doctor also includes 250 ready-to-go factory presets, which means you can load up a killer FX chain preset on your track with just a few clicks.

No need to waste time searching through endless options or building chains from scratch, which is a huge perk (and time-saver, I might add).

All you have to do is:

#1. Select 一 Select your preferred style & formula.

#2. Generate 一 Press the button to instantly generate a perfect FX chain.

#3. Customize 一 If you’d like, you can regenerate certain parameters, add additional FX and customize to taste.

One of my personal favorite things about Sound Doctor is how user-friendly the interface/display is. 

You can quickly adjust, edit, and rearrange effects on your track without any hassle or confusion like some other plugins. 

If you’re serious about creating professional-sounding FX chains without all the extra work, Sound Doctor is exactly the kind of plugin you’ll need.

Key Features

Now that you got the basics down, let’s dive into why Sound Doctor is invaluable when it comes to creating professional-quality FX chains. We’ll kick things off with the key features because they’re the reason it can completely change how you apply effects to your tracks.

• Customizable FX Chains

The first thing you’ll notice about Sound Doctor is just how flexible and customizable it is when creating your FX chains. 

You have access to 8 effect slots/channels in total, which means you can load up to 8 different insert effects on any given track. 

These effects include everything you’ll need, like: 

• Compression
• EQ
• Saturation
• Distortion
• Reverb
• Delay
• Chorus
• Modulation effects like phasers or flangers

So, imagine you’re mixing a vocal track…

First, you might load a surgical EQ in slot one to cut around 80-100 Hz to remove unwanted rumble, and gently boost around 12kHz for extra clarity and air. 

Right after that, add a smooth opto-style compressor in slot two, set to about a 4:1 ratio with a -15 dB threshold to tame dynamics without losing expression.

Next, you could apply a subtle analog-style tape saturation effect in slot three, setting the drive around 15% (just enough to give the vocal track a warmer character/feel). 

Follow this up by placing a stereo chorus in slot four 一 adjusting the depth parameter to roughly 35% and the rate around 1.2Hz.

This will add width without sounding too obvious or distracting.

In slot five, you can then load up your favorite tape-style delay effect, set to an eighth-note timing synced to your project tempo.

I suggest the feedback dialed around 20%, so it’s subtle yet adds space, but it’s dealer’s choice (remember, it’s all about tweaking things to fit your unique taster).

Finish the FX chain off in slot six with a medium room reverb, set to about 1.2 seconds decay time, and a wet/dry mix of around 18% to give the vocal track depth while keeping it front and center.

Just make sure to always save your custom FX chain presets once you nail down a great sound that you’re completely happy with.

This way, you won’t have to rebuild it every time, and your workflow becomes way more efficient, which frees you up to stay creative for any task.

• 25 World-Class Effects

Another major reason why Sound Doctor stands out is its impressive collection of 25 seriously powerful, studio-grade effects, even more rare ones like bitcrush, tremolo, and detune.

They cover every possible scenario in your production workflow, hands down.

For instance, it includes a pristine digital parametric EQ with multiple bands so you can pinpoint frequencies with surgical precision.

This is absolutely perfect  for removing mud around 250-300 Hz on a drum bus or adding sparkle to vocals around 10-12 kHz.

It also packs super versatile compressors, like the “Studio Compressor,” which lets you adjust attack and release times in milliseconds. 

I typically set an attack of about 20 ms and a release around 100ms when processing drums, making them punchier and cleaner without losing natural dynamics. 

When it comes to vocals, you might go quicker, around 5-10 ms attack, to catch transients and even out the performance smoothly.

The delay options are just as killer, featuring effects like “Vintage Tape Delay,” where you can choose between synced eighth-note or quarter-note delays.

Or, manually set a delay time in milliseconds; I personally love setting mine around 250ms for vocals, but again, totally up to you.

You can also dial in feedback to about 25% for subtle repeats that give depth without overwhelming the track.

The modulation effects (chorus, phaser, flanger) are also top-tier, and can help give your tracks unmatched dimension and width. 

For example, when using the chorus effect on a guitar or synth pad, setting a depth between 30-50% and a rate around 0.8-1.5Hz can instantly add thickness and a stereo spread that makes your track stand out in the mix.

Having all these effects in one place means you’ll spend less time browsing through your plugin library and more time knocking out legendary sounds. 

Trust me, it makes a huge difference in your final mix quality, not to mention your overall workflow speed.

Here are all the effects, so you can see for yourself:

1. Parametric EQ for precise frequency adjustments to shape your sound.​

2. Compressor to control dynamics by reducing the volume of loud sounds.​

3. Limiter to prevent audio signals from exceeding a set threshold, avoiding distortion.​

4. Saturation to add harmonic richness and warmth to your tracks.​

5. Distortion, which introduces grit and edge by altering the waveform.​

6. Bitcrusher to reduce bit depth and sample rate for a lo-fi effect.​

7. Chorus to create a thicker sound by duplicating the signal with slight variations.​

8. Flanger, which produces a sweeping effect by mixing the signal with a delayed version of itself.

9. Phaser, which generates a swirling sound by shifting the phase of the signal.​

10. Tremolo that modulates the amplitude to create rhythmic volume changes.​

11. Vibrato for slight pitch variations for expressive effects.​

12. Delay, which repeats the audio signal after a set period, creating echoes.​

13. Reverb to simulates acoustic spaces, adding depth and ambiance.​

14. Stereo Widener to expand the stereo image for a broader soundstage.​

15. Auto-Pan, which automatically moves the audio signal between stereo channels.​

16. Pitch Shifter, which alters the pitch of the audio without affecting its duration.​

17. Ring Modulator, which combines two signals to create metallic or bell-like sounds.​

18. Filter to shape the frequency content by attenuating or boosting certain frequencies.​

19. Gate, which reduces noise by silencing signals below a certain threshold.​

20. De-Esser to tackle sibilance in vocal recordings.​

21. Transient Shaper to enhance or attenuate the attack and sustain of sounds.​

22. Exciter, which adds brightness and presence by enhancing high frequencies.​

23. Tape Emulator to simulate the warmth and saturation of analog tape.​

24. Vinyl Simulator, which adds vintage vinyl characteristics like crackle and hiss.​

25. Lo-Fi Effect that introduces imperfections for a nostalgic, degraded sound.​

• 250 Factory Presets

Sound Doctor is also such a lifesaver in the studio because it comes packed with 250 professionally designed factory presets as well (can you say cherry on top).

Each one is built to enhance your tracks, no matter the genre or audio material you’re working with at the time.

For example, if you’re struggling to get your drums to punch through the mix, you can simply choose the “Punchy Drum Bus” preset.

This typically features a combination of a compressor with around a 3:1 ratio, fast attack (10-15ms), and medium release (around 80-100ms) 一 paired with a subtle EQ boost at about 100 Hz and 8kHz to add weight and clarity to your track.

If you’re working on vocals and need them to sound polished fast, the “Vocal Shine” preset instantly applies a gentle high-pass EQ filter around 120Hz.

It also adds a touch of smooth optical compression with settings around a 4:1 ratio and -18 dB threshold. 

Plus a warm analog-style delay with a subtle eighth-note timing synced perfectly to your project tempo to make the final connection.

Bass tracks are equally easy to transform…

Simply load the “Deep Bass Enhancer” preset, which usually combines low-frequency saturation around 60-80 Hz with a precise compressor dialed in at a: 

• Moderate ratio (like 3:1)
• Controlled attack around 20ms
• Quick release (40-60ms) to keep your bass punchy yet controlled

The real beauty of these presets is how much time they save 一 letting you quickly load epic FX chains, while still being able to easily adjust and tweak parameters.

Everything can be set to match your unique, regardless of vibe, style, or genre.

And again, don’t forget to play around with these presets and save your absolute favorites as custom FX chain presets to make similar audio tasks much easier/quicker.

Creating Professional FX Chains with Ease Using Sound Doctor

I know I’ve given you some killer examples now, but I figured I’d break down some more so you can really see how powerful Sound Doctor is even more. If you want your tracks to have professional-grade FX chains, buckle up.

• Enhancing Your Drums & Percussion

When your drums aren’t cutting through the mix, Sound Doctor can quickly solve that issue, like we touched up. 

Try selecting the “Tight Drum Enhancer” preset, which typically includes a compressor set to a medium-fast attack (around 12-15ms) and short release (around 50ms) to keep your drum transients tight without killing their punch. 

Next, blend in some subtle parallel saturation, around 20-25% drive, to add warmth and energy, which is super useful for snare hits or percussion loops. 

Personally, I also love tweaking the stereo image by applying slight mid-side EQ adjustments.

Make sure to gently narrow frequencies below 150 Hz to mono keeps the kick punchy, while a subtle stereo boost at around 4kHz-8kHz opens up cymbals and hi-hats.

• Processing Vocals and Melodies

Vocals need clarity and brightness, that’s a given, and luckily Sound Doctor has got your back in this respect as well.

Instead of reaching for standard vocal presets, try customizing your FX chain by first applying a transparent compressor (like the “Modern Vocal Comp”).

I recommend a moderate ratio of about 3:1, fast attack (10ms), and smooth release (about 100ms) to control dynamics naturally. 

Afterward, add an airy EQ lift at roughly 15kHz (2-3 dB) and roll off unnecessary lows below 100Hz to maintain vocal presence without muddiness. 

Follow this with a stereo slap-delay effect set to around 120 ms delay time with feedback under 15% 一 perfect for adding depth without cluttering your mix. 

My only comment would be to finish off your chain with a subtle plate reverb (about 1-second decay) at around 15% wet to provide space.

This will keep your vocals upfront and professional-sounding all day.

• Transforming Bass & 808s

To get your bass tracks sounding clean yet powerful, try creating an FX chain specifically for low-end definition. 

Begin with Sound Doctor’s parametric EQ to create a focused bass tone by cutting muddy frequencies around 250Hz by about 3-4 dB.

Then boost the sub-region slightly around 50-70 Hz for extra weight. 

Next, carefully apply harmonic saturation (around 15-20%) to enhance higher bass frequencies between 200Hz-500Hz.

This makes it easier to hear on smaller speakers without losing depth. 

Follow this with precise compression, using settings around a 4:1 ratio, medium attack (around 30ms), and a fairly quick release (50-60ms), to control dynamics while keeping the attack intact. 

One of my favorite pro moves is subtly adding a mono-compatible chorus effect at about 8-10% depth only to mid-bass frequencies.

It’ll give your bass lines a fuller character without sacrificing any low-end integrity.

Bonus Tips for Maximum Creativity

Last but not least I’ll leave you with some bonus tips for MAX creativity because there’s much more you can do with Sound Doctor other than just loading factory presets. 

One thing I’d definitely suggest is that you take full advantage of its user-friendly window and edit your FX chains directly from the plugin’s browser.

This way you can choose and assign parameters quickly while never getting blocked creatively (which is a big deal to producers like us).

For example, try creating your own custom FX chain preset by loading unique combinations of modulation effects.

You can pair a phaser (set at a slow 0.3Hz rate and medium depth) with subtle stereo delays around 150ms for captivating textures on melodic audio tracks. 

Another helpful procedure is to clearly name and save your customized presets after tweaking the parameters 一 placing them neatly into folders so they’re easy to find.

You can even switch between saved FX chain presets in real-time while your track is playing back, comparing options without disrupting your creative flow. 

Also, don’t overlook Sound Doctor’s built-in search feature, which helps locate the perfect preset or individual effects instantly.

I know it seems like a tiny little thing, but it can really speed up the creative task, leaving you more time to experiment, and every minute counts. 

And, for performance-heavy audio sessions, remember to adjust and display only necessary insert effects on your tracks.

This will reduce CPU load and help you maintain a smooth workflow. 

Finally, don’t forget to regularly check Unison Audio’s website and update page to navigate new bundles, options, and helpful buttons that can keep your FX chains fresh, professional, and inspiring every time you produce.
