Sinevibes has released Array 4, a major update to their spectral sequencer effect plugin for Linux, Mac and Windows.

Using multiple crossover filters, Array splits audio into 8 frequency bands that are separated exactly one octave apart. Each band then runs through a gate controlled by an advanced step sequencer – allowing you to carve the audio spectrum in precise rhythmical fashion.

The official video intro:

The sequencer holds a total of 8 different gate patterns, with up to 32 steps each, and offers a wide range of timing settings for creating polymetric or polyrhythmic motion in any time signature.

The gate switches on every frequency band are shaped using a two-pole low-pass filter. Combined with the unique design of the filter section, this timing engine makes Array an versatile instrument for complex rhythmical manipulation of the sound spectrum.
Features:

• Clean, neutral -24 dB/octave crossover filters that split audio into 8 frequency bands, tuned one octave apart
• Optional state-variable, resonant band-pass filters per each frequency band, tuned one octave apart, with adjustable slope
• Individual gate sequence per frequency band, with 8 separate sequence patterns per preset
• Step sequencer with rhythmically correct swing, polymetric and polyrhythmic abilities
• Two-pole analog-style lag filters for variable gate transition smoothing
• Progressive bipolar pan spread between the frequency bands
• One-pole lag filters on all continuous parameters for smooth, click-free adjustment
• Supports mono › mono, mono › stereo, and stereo › stereo channel configurations

Compatibility:

• Linux: VST3 for Linux 2020 or newer (64-bit Intel and AMD
• Mac: AU/VST3/AAX for macOS 10.13 or newer (64-bit Apple Silicon and Intel)
• Windows: VST3/AAX for Windows 8.1 or newer (64-bit Intel and AMD)

Array 4 is available now for $29.
