Spring Reverb models the sound and character of popular spring reverbs found in guitar amplifiers, popularized by Surf, Garage and Rockabilly music. Spring takes this a step further by allowing manipulation of physical parameters not normally available in a real spring tank. The results vary from faithful recreations of real springs to distinctive new sounds that push the physical boundaries of reverb. Guitarists love the revered surfer vibe but all creative musicians will find that Spring makes any synthesizer, drum, or vocal stand out in a mix. This vintage reverb sound originally derived from the reflections of sound waves traveling through springs has been given an overhaul for the 21st century and beyond. Eventide Spring contains two different sized ‘spring tanks’ along with the ability to morph between one and three springs. Easily program The Ribbon to seamlessly transition between any two settings in real-time! The added tube-amp-style tremolo can be routed before or after the spring resulting in an unrivaled ability to craft your own unique reverb sound. Alter the intensity by changing the tremolo depth and adjust the tremolo rate in Hz, or note value when tempo-synced to your project. Features: - Artist presets by Matt Lange, Nick Hook, and Nu-Trix. - Tempo Sync reverb decay to your DAW. - Craft original sounds by changing the number of springs and damping frequency. - Alter overall resonance by selecting the size of the spring tank. - Tube-amp-style tremolo that can be routed pre- or post-reverb. - Create chorus-like effects by altering Modulation Level. - The Ribbon controller allows for dynamic modification of several knobs at once to easily morph between settings. - Programmable Hotswitch provides the ability to jump instantly to an alternate sound at the push of a button. - Available as an Audio Units AUv3 plug-in and Standalone App.

In our seventh collaboration with Berlin-based musician Hainbach we listen to the stars: Moon Echo is a free to download delay based on a communications technique that uses our closest cosmic neighbor, the moon, as a reflector for radio waves. This results in some rather crunchy and lively echoes, modulated by the movement of Earth and moon. The moon's surface is an imperfect mirror and creates artifacts, unlike any other echo technique. Moon Echo is both a musical lo-fi effect and a playful tool for teaching about space. Available as AUv3 and Standalone.
