*** 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.

BLEASS Delay is the ideal tool for adding depth, movement and interest to your mixes. Whatever style of music you produce and whatever instruments you work with, its versatility and ease of use help you achieve perfect results with the minimum of fuss.

BLEASS Delay also includes three LFOs, one each for the delay engine, the frequency shifter and the filters. As well as classic modulation effects such as chorus and flanging, these dedicated LFOs are ideal for creating exciting sound effects and epic, constantly-shifting soundscapes. FEATURES • Delay time synced to your host tempo (note values, including triplets) or set freely in milliseconds • Ping Pong mode with adjustable stereo width • Frequency shifter applied cumulatively to each repeat • Low pass and high pass filters: drag on the graph to set cutoff and resonance • Three LFOs, each with depth, rate and stereo phase offset up to ±180° • Feedback from a single echo to infinite repeats • Dry/Wet control • Preset manager with factory and user presets, plus a preset generator • Clear single-screen interface on iPad and iPhone WORKS WHERE YOU MAKE MUSIC BLEASS Delay is an AUv3 plugin.
