VoltusFX

VOLTUS FX is a free analog-modeled BBD delay and saturation processor for Windows and macOS.

Built around a custom Bucket Brigade Device delay line and a dual-stage saturation engine, Voltus FX is designed to behave like imperfect analog hardware rather than a clean digital delay. It intentionally avoids clinical oversampling, allowing the modeled circuits to intermodulate, color, degrade and break up in a musical way.

From warm vintage echoes and thick chorus to metallic flanging, string-machine style ensemble textures, tape-like drift and full signal destruction, Voltus FX delivers a wide range of analog-inspired effects in a simple, immediate interface.

Main features:

• Custom-modeled Bucket Brigade Device delay.
• Four delay modes: Delay, Chorus, Flanger and Ensemble.
• Dual saturation engine with Tube Drive and Diode Drive.
• Tube Drive: asymmetric triode-style soft clipping with warm harmonic character.
• Diode Drive: germanium-style clipping for harder, more aggressive saturation.
• Character control for clean-to-aged circuit behavior.
• Modeled circuit noise injected into the feedback path at higher Character settings.
• Six LFO waveforms: Sine, Triangle, Saw, Square, S&H and Drift.
• Drift LFO mode for random tape-like modulation movement.
• Chamberlin-style State Variable Filter with adaptive dynamic stability.
• Zero-latency processing for real-time performance.
• 30+ factory presets included.
• Free.

Technical specifications:
