Shimmer reverb: create pads that rise in octaves
2 min read · Updated
Shimmer reverb produces those luminous tails that seem to rise into the sky. The principle is simple: the sound is pitch-shifted inside the reverb loop, on every pass. Well dosed, it turns a held note into a pad; overdone, it takes over everything. Here is how to master it.
In short
- Put the shimmer on a send, at 100% mix.
- Start at +12 semitones (one octave), or +7 for a fifth.
- Raise the feedback to make the effect climb further.
- Lower the tone if it gets too bright.
- Keep it low under a vocal, higher on a pad.
How it works
In a shimmer reverb, a pitch shifter sits in the feedback loop. The reverberated sound is pitch-shifted, fed back into the reverb, shifted again: the tail gains an octave, then another. With a downward shift, the tail darkens instead of shining.
The settings that matter
Pitch shift: +12 (one octave) is the classic sound, +7 (a fifth) is more harmonic, +24 very airy. Feedback: the higher it is, the more the sound climbs and lasts. Tone: lower it if the highs get harsh. Size and decay set the space around it.
Lontana Shimmer offers three modes: Single, Dual (up and down) and Reverse, with a pitch shift of ±24 semitones and a stabilized loop that never runs away. Its 31 presets cover pads, guitars, vocals and cinematic sounds.
Where to use it
On arpeggiated guitar or piano, for an ambient pad. On a vocal, very subtly, to add air on held notes. At the end of a song, for a note that turns into texture. On a simple synth, to get a rich pad from a thin sound.
Avoid it on very rhythmic sounds: successive pitch shifts blur the attacks.
Frequently asked questions
- What is a shimmer reverb?
- A reverb with a pitch shifter in its loop: the tail rises (or falls) by an interval on each pass, creating luminous pads.
- Which pitch shift should I choose?
- +12 semitones (one octave) for the classic sound, +7 (a fifth) for a more harmonic effect.
- Why does my shimmer get shrill?
- Feedback or tone is too high. Lower the tone, reduce the feedback or cut the reverb's highs.
- Can you put shimmer on vocals?
- Yes, on a send and very subtly, especially on held notes: it adds air without blurring the lyrics.
