Aqeel Aadam Sound has introduced a playable harmonic filter for Windows, macOS and iOS.
Designed for adding tonality, motion, and interest to sound, Sightlines is built around an idea from Outgrowth‘s harmonic filter, but turned into a smaller, more focused instrument.
The plugin can be loaded as either an instrument or an audio effect, tuned to a fixed frequency like a resonator or played over MIDI to bring it alive as a pitched voice. As an instrument it filters noise, samples, or oscillators into new sounds; as an effect it adds movement and tonality to any incoming audio, even unpitched material. The filter bank concept first appeared in the developer’s sampler Outgrowth and has now been expanded into a dedicated, more affordable standalone tool.
Sightlines features
- Noise and sample sound sources, with samples playable as one-shots or infinite loops.
- Overtone manipulation for stretching, bending, and reimagining the harmonic series.
- Frequency quantizing to snap all filter bands to a chosen scale.
- Band balancing through scanning, tilting, and spreading across the harmonic space.
- Built-in chorus, BBD-style delay, and reverb.
- Modulation via multiple LFOs, sequencers, smooth random sources, and performance effects, plus full cross-platform preset support.
Sightlines also integrates with the Waymaker sequencing application for additional pitch and control options.
Available in VST3 and AU plugin formats for Windows and macOS, Sightlines is on sale at an introductory price of $20 USD for a limited time (regular $30 USD). The iOS/AUv3 version is $7.99 USD on the App Store.
