The unique pitch-shifting reverb in BLEASS Shimmer makes performances dance and sing in ways you never imagined possible. Harmonics are emphasised and new tonal colours emerge as luscious washes of reverb thicken and harmonise with your performance, opening up a whole new creative dimension of spatial and ambient effects. The flexible processing architecture makes BLEASS Shimmer a highly versatile plugin overflowing with creative musical possibilities. Shape the incoming sound with the multi-mode input filter, place the two pitch-shift modules at different points in the signal chain for wildly different results, and combine them with a clean, rich reverb. An integrated ducker helps the direct signal stand out from the reverb and is perfect for rhythmic and blooming effects. This vast sonic potential is easy to tame, both live and in the studio, thanks to a clear and tactile interface designed for hands-on exploration. More than 30 included presets reveal the depth of possibilities on offer while providing great starting points for your own sound designs. From guitars and synth pads to leads, vocals and drums, BLEASS Shimmer brings exciting new dimensions to your musicianship. More information and technical specifications available on https://www.bleass.com/shimmer/ BLEASS Shimmer can be launched as an AUv3 plugin or as a standalone app. BLEASS Shimmer is also available for Windows, and macOS.
