How to Get a Dreamy Lo-fi Reverb Sound (Meet MWA Haze)
By Omar Meho, 13 November 2026
That dreamy, worn sound on lo-fi house keys and melodic pads is not one effect. It is a reverb plus a bit of tape, a bit of age and a bit of dust. Here is the recipe, and the plugin I built to do it in one go.
The recipe
- A big, soft reverb with a darker tone, so the tail sits behind the sound.
- Movement inside the tail, so it never sounds static.
- Tape drift: a slow wobble in pitch, like a tired tape machine.
- Warmth: gentle saturation that rounds off the edges.
- Age: trim the very low and very high end so it sounds older.
- Dust: a little crackle and hiss, only while the music plays.
Keep it out of the way
The trick that makes it sound expensive is ducking. The reverb dips while the chords play and swells back in the gaps. Your keys stay clear and the space still feels huge.
MWA Haze
Haze puts all of that in one window. On the left: size, decay, pre-delay, tone, width, shimmer, movement, ducker and FREEZE. On the right: Drift, Warmth, Crush, Age and Dust, with one Colour knob that turns all five up together. You choose whether the colour goes on the reverb only or on everything.
There are 11 presets, from Dream Pad Space and Melodic Techno Lead Wash to Lo-fi House Keys and Old Cassette. Mac (AU and VST3), £29, and included in the MWA Bundle.
A quick move to try
Put Haze on a return track, send your chords to it, load Lo-fi House Keys, then switch on FREEZE on the last chord before a drop and off on the first kick.
