Read full description

Concept: “shortReverse II” is the advanced version of “shortReverse” which was previously released. The second has the same functionality as the first but resolves professional needs, that is, the problem of restricted buffer size (2^N). Now the user can freely adjust the buffer size from 256 to 65536 (in 1 sample unit). Usage: The user can reverse an incoming audio signal in real-time only while pushing the button. "buffer size" slider is text-editable by clicking. Note: Button automation in DAW is not supported. System Requirements: AUv3 host stereo output: just plug headphone/mic or audio interface.

Heavier Metal is a modern distortion plugin based on one of the most aggressive pedals of the 1990s. Built using Artera DSP’s Parametric NAM engine, it delivers not just the sound — but the full behavior of the original circuit. Every knob. Every nuance. Captured with precision. This isn’t a snapshot. Heavier Metal is fully parametric — meaning all front-panel controls respond just like the original analog pedal. From razor-sharp riffs to soaring leads, it gives you the full expressive range of the original hardware, with the flexibility of a native plugin. Key Features – Fully parametric NAM model — not a static capture – Recreates the full tone-shaping behavior of the original HM-style pedal – Mid-forward gain structure with massive sustain and tight low-end – AUv3 plugin for macOS and iOS – Native support for Apple Silicon (M1/M2) – Ultra-low CPU usage and near-zero latency Compatibility Heavier Metal runs in any AUv3-compatible host such as Logic Pro (Mac/iPad), GarageBand (Mac/iOS), AUM, Cubasis, and more. Available exclusively on the App Store.
