Minimal Audio Flex Chorus — Free Download
Flex Chorus is a dual-mode chorus plugin from Minimal Audio, offering up to 24 voices, multi-band processing, and flexible controls for creating depth, width, and movement in audio.

Purpose and Core Modes
Flex Chorus is designed to add movement, width, and depth to audio using two distinct chorus algorithms. The Smooth mode leverages human frequency perception to produce a rich, deep sound, while the Glass mode uses a modern multi-stage approach for bright, glistening stereo effects. These modes offer contrasting characters to suit different musical contexts.
Both modes are built for flexibility, allowing you to shape the effect from subtle to extreme. The choice between Smooth and Glass lets you match the chorus to the source material, whether you need a warm analog-style thickening or a sparkling, modern texture. This dual-mode design gives you a creative starting point for various production styles.
Key Capabilities
The plugin supports 2 to 24 voices, each with independent time and modulation depth controls, enabling everything from classic chorus to massive unison effects. Per-voice randomization adds organic variation, and BPM sync allows rhythmic modulation. The Lush Feedback feature introduces detuned tails or resonant spaces depending on the selected style, while multi-band and filtering controls let you isolate the effect to desired frequency ranges.
A visual delay-tap display shows how voices are distributed across the stereo field, making it easy to understand and adjust the spatial image. In-app tooltips provide guidance for learning the plugin, and the preset library includes over 40 presets for a variety of uses, from essential stereo enhancement to dense detuned spaces.
Workflow and Integration
Flex Chorus is designed for seamless integration into a mix. The onboard multi-band and filtering controls let you preserve low-end clarity or widen only the high end, ensuring the effect doesn’t muddy the mix. You can activate these modes to keep the chorus exactly where you want it, whether on a specific instrument or across a full mix.
The flexible controls, including independent time and depth, per-voice randomization, and BPM sync, make it suitable for both subtle stereo enhancement and dramatic, detuned textures. The delay-tap display provides real-time visual feedback, helping you fine-tune the stereo image. The preset library offers a quick starting point for different styles, and tooltips aid in learning the plugin’s workflow.
Practical Applications
Use Flex Chorus for essential stereo enhancement on tracks that need width without excessive movement. The multi-band mode is ideal for keeping the low end centered while widening guitars or pads. The Glass mode excels on high-frequency elements, adding a glistening sheen to synths or cymbals.
With up to 24 voices, you can create dense detuned spaces for sound design or massive unison leads. BPM sync ensures the modulation is in time with your project, making it practical for rhythmic parts. The diverse presets provide a convenient starting point for styles like pop, electronic, and experimental music.
