Hidden Features in MReverb You Should Be UsingMReverb is a powerful, versatile algorithmic reverb that can deliver everything from realistic room spaces to lush, otherworldly atmospheres. Many producers use its basic controls — pre-delay, decay, diffusion, damping, and mix — but MReverb contains a number of lesser-known features and workflow tricks that can dramatically improve your mixes and speed up creative decisions. This article walks through those hidden features, explains why they matter, and gives practical examples for immediate use.
1. Early Reflection Shaping for Perceived Space
Most users tweak only the overall decay time and size, but the early reflections are what tell the ear about the room’s shape and proximity. MReverb’s early reflection controls let you sculpt the initial response separate from the tail.
- Why it matters: Early reflections influence perceived distance and width. A brighter, dense early reflection can push a sound forward; sparse, delayed early reflections push it back.
- How to use it:
- Increase early reflection level for close, intimate sounds (vocals, acoustic guitar).
- Reduce early reflection density and boost pre-delay to place a source farther back without muddying the mix.
- Combine asymmetric early reflections (if available) to add a lateral spaciousness that feels wider than simple stereo widening.
Example: For a pop vocal, set pre-delay to 18–25 ms, slightly raise early reflection level for presence, and lower tail level to keep clarity.
2. Modulation Section for Lush Tails and Movement
MReverb often includes modulation parameters that subtly pitch-modulate the reverb tail or apply stereo motion. These are commonly overlooked because heavy modulation can introduce chorus-like artifacts.
- Why it matters: Gentle modulation breathes life into static reverb tails, preventing metallic ringing and making pads, synths, and ambiences feel organic.
- How to use it:
- Set modulation rate very low (0.1–0.6 Hz) and depth modestly (1–8%) for natural motion.
- Increase depth for creative, dreamy textures on pads or vocal doubles.
- Use tempo-synced modulation where available for rhythmic movement tied to the track.
Example: On a synth pad, set modulation rate to 0.25 Hz and depth to 5% to create a slow, evolving shimmer.
3. Frequency-Specific Damping and EQ in the Reverb Path
Beyond a single damping control, MReverb’s internal EQ or multi-band damping lets you control how different frequency bands decay. This is crucial for avoiding low-end buildup and keeping reverbs from masking vocals.
- Why it matters: Different instruments excite different frequency ranges. Tailoring decay across bands keeps clarity and maintains tonal balance.
- How to use it:
- Low-frequency roll-off: tighten the low end by reducing decay time below ~200 Hz.
- Mid-range clarity: attenuate excessive 300–800 Hz energy to prevent boxiness.
- High-frequency shimmer: add a slight high-shelf boost in the tail for presence, or increase HF damping for vintage, darker rooms.
Example: For a snare reverb, shorten low-frequency decay and keep mid/high decay longer for snap without muddiness.
4. Predelay Modulation and Tempo Sync Tricks
Predelay is typically static, but adjusting it dynamically or tempo-syncing it can create rhythmic space and prevent masking. Some MReverb versions support tempo-sync or automation of predelay.
- Why it matters: Tempo-synced predelay places the reverb attack musically relative to the groove, and automating predelay can create creative transitions.
- How to use it:
- Sync predelay to dotted or triplet subdivisions to match the groove.
- Automate predelay during pre-choruses to push vocals forward, then shorten it in choruses for a more cohesive blend.
- Use very short predelays (10–30 ms) to keep perceived proximity while still separating direct sound.
Example: For a groove at 120 BPM, try a predelay of 125 ms (quarter note) or 83 ms (eighth-note triplet) to align the reverb with rhythmic hits.
5. Sidechain/ ducking and Dynamic Reverb Control
Dynamic control over reverb level is a powerful but underused technique. If MReverb has an internal sidechain or ducking capability, use it; otherwise, pair it with a compressor or gate on the reverb bus.
- Why it matters: Ducking prevents the reverb from competing with the dry signal during transient-rich parts, preserving attack and clarity.
- How to use it:
- Sidechain the reverb to the dry track (kick, vocal, or snare) so the reverb level reduces when the dry signal is present.
- Use a fast attack, medium release to let the tail return naturally.
- For gates: set the threshold just below the instrument’s sustain to clear reverb between phrases.
Example: Sidechain vocals so the reverb ducks while lyrics are sung, then breathes back in during gaps and longer notes.
6. Stereo Width and Mid/Side Processing
MReverb may include independent control over stereo width or an M/S mode. Using mid/side processing on reverb returns improves clarity and placement.
- Why it matters: You can keep the center elements tight while creating large, immersive side information without messing with mono compatibility.
- How to use it:
- Reduce mid reverb level and increase side reverb to widen ambience without blurring the vocal or lead.
- Use more high-frequency damping on the mid channel to keep center elements intelligible.
- When using an M/S-capable plugin, fold mids in mono occasionally to check phase and compatibility.
Example: For lead vocals, reduce mid reverb by 2–4 dB and raise side reverb for a spacious stereo image that doesn’t smear the vocal.
7. Reverse Reverb and Pre-Decay Effects
Some versions of MReverb include reverse or pre-decay features that create swells leading into transient hits. If not built-in, you can create reverse effects by reversing audio, applying MReverb, and reversing again.
- Why it matters: Reverse reverb is great for transitions, fills, and adding an ethereal character to vocals and leads.
- How to use it:
- Create a short reverse reverb tail and layer it under the main dry signal to create a sucking-swell effect into a phrase.
- Automate mix or pre-delay for controlled intensity.
- Use high damping on the reversed tail to avoid overwhelming low frequencies.
Example: Reverse a vocal phrase, apply MReverb with a short decay, re-reverse, and place it before the original phrase at -20 to -60 ms.
8. Tail Layering and Parallel Reverb Chains
Combining multiple MReverb instances or routing through different reverb types yields complex, realistic spaces.
- Why it matters: Real acoustic spaces contain multiple reflection densities; layering lets you simulate that complexity without unnatural artifacts.
- How to use it:
- Create a short plate-style reverb for presence and a long hall for ambience; blend to taste.
- Use different EQs on each reverb to carve space for each layer.
- Pan one reverb slightly and keep another centered for depth.
Example: Snare — short bright plate (decay ~0.6s) + longer room tail (~1.8s) with low-cut on both.
9. Using Preset Morphing and Focused Preset Editing
MReverb often ships with many presets; morphing between them or editing presets with focused changes is faster than building from scratch.
- Why it matters: Presets provide useful starting points. Morphing reveals intermediate textures you might not design intentionally.
- How to use it:
- Pick two contrasting presets (small room vs. large hall) and morph parameters where available to find unique hybrid spaces.
- Tweak only one parameter at a time (e.g., damping or diffusion) to hear its musical effect.
- Save user presets with naming that includes instrument/context (Vocal Short, Drum Ambience, Pad Dream).
Example: Morph between “Vocal Plate” and “Cathedral” and then reduce decay by 30% to fit the mix.
10. Automation for Expressive Spatial Design
Automating reverb parameters across a song creates evolving spaces that match arrangements and emotional arcs.
- Why it matters: Static reverbs can make long tracks feel stagnant. Automation turns space into a compositional tool.
- How to use it:
- Automate decay and mix for transitions: increase decay in breakdowns, reduce in dense sections.
- Automate predelay for perceived movement (longer in sparse sections, shorter in dense choruses).
- Automate high-frequency damping during bridges to create darker moods.
Example: Slowly increase decay by 30% over the bridge to enhance emotional lift into the final chorus.
Quick Workflow Cheatsheet (Practical Settings)
- Vocals (lead): Predelay 18–25 ms; decay 1.0–1.8 s; early reflections up; mid reverb down. Damping: moderate HF roll-off.
- Drums (snare): Short plate for snap (0.4–0.9 s) + longer room for ambience (1.5–2.5 s); low-frequency decay shortened.
- Pads: Decay 3–6 s; modulation low/medium; high damping lightly applied for sheen.
- Acoustic guitar: Small room with early reflections emphasized; predelay 10–20 ms; decay 0.8–1.6 s.
Common Mistakes and How to Avoid Them
- Overusing long tails: Duck or sidechain reverb to avoid masking.
- Ignoring EQ: Always high-pass the reverb bus ~80–120 Hz to prevent low-end buildup.
- Mono incompatibility: Check reverb in mono and keep critical mids conservative.
- Heavy modulation: Use subtle depth and slow rates unless intentionally creative.
