With up to four fully stereo chorus voices, BLEASS Chorus can create everything from subtle movement and gentle thickening to rich, complex modulations, while offering precise control over stereo width, prominence and intensity. In high-pass mode, the input filter is perfect for bringing out the space and airiness within a sound, before the advanced modulation engine makes that airiness shimmer and dance. Switching the filter to shelving mode opens up a whole new range of possibilities, from deliciously warm thickening effects to sparser, thinned-out lo-fi modulations. The detailed and colourful oscilloscope at the centre of the BLEASS Chorus interface shows you at a glance exactly what the plugin is doing. Thanks to the super-efficient BLEASS processing engine, this helpful visualisation won’t come at the expense of your system’s resources. More information and technical specifications available on https://www.bleass.com/chorus/ BLEASS Chorus can be launched as an AUv3 plugin or as a standalone app. BLEASS Chorus is also available for Windows and macOS.
