Unfiltered Audio Sandman Pro
20 free presets for Unfiltered Audio’s incredible delay plugin ranging from hypnotic delays to downright weird textures for sound design. Just download, unzip and place the ‘Marula Music’ folder in your user presets folder. (MacOS: user/library/audio/presets/unfiltered audio sandman pro/)
Be sure to try them out on different source material. Some of them work better on pads and synths, others on percussion.
