Every version.
What matters.

Added

• Hold Option on macOS or Alt on Windows/Linux while dragging Cutoff to tune in semitone steps (A4 = 440 Hz). Normal adjustment and DAW automation remain continuous.

Changed

• Alt/Option-click no longer resets any dial. Use double-click to reset it.

Added

• Cutoff shows the nearest note and cents deviation, and accepts note names as well as hertz. Notes without an octave use octave 1 (G = G1, about 49 Hz).
• Optional Help mode explains each control and the selected filter model.

Changed

• Gain and Drive are easier to adjust precisely, with finer control near 0 dB.
• Rate reaches 30 Hz for Phaser, Barberpole, Flanger and Barber Flange, with smoother control of slow modulation in both the plug-in and DAW automation.
• Output is now called Gain and adjusts only the filtered signal before Mix. Mix at 0% leaves the dry level unchanged.
• Shift-drag makes fine adjustments. Cmd-click on macOS or Ctrl-click on Windows/Linux opens keyboard value entry.
• Cutoff displays two decimal places across its full range for precise tuning.

Compatibility

• Saved settings are preserved, but existing normalized Gain, Drive and Rate automation maps to different values. Check those lanes after updating.
• Moving Gain before Mix can change partial dry/wet blends when Gain is not 0 dB.

Added

• One-command macOS installation with verified downloads and automatic selection of the appropriate package.
• macOS ZIPs include an offline AU, VST3 and CLAP installer. No administrator access is needed, and previous versions are backed up.

Installer update only: the plug-in remains version 0.3.3, with no audio changes.

Changed

• Cutoff extends down to 1 Hz, with a dedicated low-frequency range for smooth sub-bass sweeps. The dial and DAW automation use the same curve.
• Extended sub-audio operation across the filter engines, including Comb and Flanger, so the lower Cutoff settings affect the sound correctly.

Compatibility

• Saved Cutoff settings remain in hertz. Existing normalized automation curves address different frequencies after this range change; check existing sweeps.

Fixed

• Cutoff automation now follows the same logarithmic curve as the dial in VST3, AU and CLAP, including Bitwig. Knob position and automation now match.

Added

• Added a stereo output meter with peak memory and an overload warning.

Changed

• Reduced excessive level build-up at higher Quad Peak Resonance, without added latency or automatic gain pumping.

Added

• Added Quad Peak, a four-peak stereo formant filter. Radiate L/R independently controls peak spacing on each side; 4-Peak Mono combines all four peaks in one response. Works with Age for analog variation.
• Added Low Pass, Band Pass, High Pass and a dry-preserving Vocal response.

Fixed

• Improved CLAP parameter compatibility and value updates after restoring a saved project.
• Corrected macOS compatibility information for macOS 11 and later.

Changed

• Cutoff is easier to tune at low frequencies, without an oversized step between 20 and 21 Hz. Existing automation remains compatible with 0.2.0.
• Simplified the frequency readout for easier reading.

Added

• Improved antialiasing in the OTA and Transistor models for cleaner sound under heavy Drive and during resonant sweeps.
• Added 8x oversampling and improved oversampling quality throughout. Auto + Ultra selects the higher-quality processing path automatically.
• Added Age: component variation, slow thermal drift and internal headroom modelling for a more individual analog character. Each instance recalls the same hardware profile with the project; Age at 0% remains neutral.

Added

• Added a global dry/wet Mix control.
• Added native releases for macOS, Windows and Linux.

Changed

• Redesigned the interface with clear model descriptions and controls that adapt to the selected filter.
