Read full description

EverSpace is an algorithmic reverb designed for creating enormous spaces, evolving ambience and richly modulated echoes. Built upon the CloudSeed engine by Ghost Note Audio, its architecture draws inspiration from the algorithmic studio reverbs of the 1980s, where networks of delays and diffusion were used to create spaces that extended far beyond the limits of the physical world. Rather than attempting to recreate a particular room, hall or vintage hardware unit, EverSpace embraces the more creative possibilities of algorithmic reverb. Dense diffusion, multiple delay stages and extensive modulation allow sounds to bloom into vast, constantly moving environments — from spacious reflections and drifting echoes to seemingly endless atmospheric tails. At more extreme settings, EverSpace becomes much more than a conventional reverb. Simple sounds can be transformed into thick evolving pads, shimmering textures and expansive ambient soundscapes, with subtle variations within the reverb network ensuring that the resulting space remains alive and in motion. EverSpace can be used as a traditional send or insert effect, but it is at its best when treated as a creative sound-design tool where the reverb itself becomes part of the sound. Features ○ CloudSeed algorithmic reverb engine — a sophisticated multi-stage architecture inspired by classic algorithmic studio reverbs. ○ Early reflection and diffusion network — control density, delay, modulation and feedback to shape the initial character of the space. ○ Extensive late-reverb section — create everything from diffuse ambience to enormous, slowly evolving reverb tails. ○ Deep modulation — independently shape the movement of diffusion and delay stages for lush, animated spaces. ○ Multi-tap delay stage — adds rhythmic reflections, echoes and additional complexity before the main reverb network. ○ Integrated equalisation — low and high frequency shaping plus filtering to sculpt the colour and decay of the reverb. ○ Seed controls — regenerate the internal delay and diffusion structures to produce different variations from the same settings. ○ Interpolation modes — alter the behaviour and character of the internal delay network. ○ Real-time visualisation — waveform and frequency displays provide visual feedback as sounds enter and evolve through EverSpace.

Make noise, texture, and percussion sing. Add motion and stereo spread to basic sounds. Load samples and sculpt them endlessly. Leave your mark on any sound with harmonic filtering. Sightlines is a playable harmonic filter. Built from a collection of resonant bandpass filters tuned to the harmonic series, designed to bring out a customizable set of musical frequencies in any sound. Tune it to a fixed frequency like a resonator, or send it MIDI to make it come alive as an instrument. Sightlines can be loaded as an instrument or an audio effect. As an instrument, use it with samples, noise, or oscillators to construct sounds never heard before. As an effect, add movement and interest to any sound, and even impart tonality onto unpitched input. SOUND SOURCES • Noise – filter variable color noise and random noise bursts for Sightlines’ simplest and quickest output. • Samples – send samples through resonant filters as one-shots or infinite looping versions of themselves, great for found sound and tonal samples alike. • Synth – skip the filters entirely and use Sightlines as a harmonic synth, where you can customize and modulate the proportion of each harmonic in the signal. • Audio effect – use Sightlines as an audio effect on any track. MOVEMENT AND EFFECTS • Manipulate overtones – stretch, bend, and reimagine the harmonic series to retune Sightlines’ output into realistic or indescribable sonic spaces. • Quantize frequencies – snap all of Sightlines’ filters to a scale, to impart that key quality onto any sound. • Balance bands – maneuver through the harmonic space by scanning, tilting, or spreading Sightlines’ bands. • End of chain – make your output shine with a built-in chorus, BBD-style delay, and reverb. FEATURES • Modulation – modify any control in Sightlines with multiple LFOs, sequencers, smooth random sources, and performance effects. • Presets – full preset control over every parameter in Sightlines. Cross-platform preset format for sharing with friends. • Waymaker – connect to Sightlines’ sibling application, Waymaker, for direct sequencing of Sightlines’ without MIDI routing. Also available for macOS and Windows in VST3 / AU / AAX formats from Aqeel Aadam Sound.
