*** Note: this is an Audio Unit Effect Plugin (AUv3) which requires a compatible host or DAW to work. *** Kosmonaut is Multitap Delay with a twist. In addition to adding echoes to your audio, it packs a bunch of extra tools to put your music in space: - Tape looper with with variable sound-on-sound decay level - 4-Tap Delay (placed in series for complex feedback loops) - LP/HP filters with LFO - Autopanner - Ambiance Generator - Haas Effect Processor (aka 'wavefront precedence effect') All features are demonstrated extensively in a ton of factory presets, and you can easily add your own user presets, which will automatically carry over across different host apps. All variables are exposed as AU Parameters in hosts which support automation. It also has a smart Random-feature, which may come up with usable results :-) Check out ruismaker.com for the user manual and audio demos.

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.
