Aspen Instruments Black Diamond Distortion v1.1.23 VST3 AU WiN MAC LiNUX + Community Presets

Black Diamond Distortion is a free distortion plugin from Aspen Instruments that lets you design your own waveshaping curves rather than just picking a preset. It works as a VST3/AU plugin on Windows, macOS, and Linux, and fits into FL Studio, Ableton Live, or Logic. The engine combines four curve-editing modes—Harmonic, Spline, Brush, and Equation—inside a multi-lane mixer. You can blend, scan, or stack these lanes in series to create anything from gentle preamp warmth to harsh modern distortion. Version 1.1 adds magnetic hysteresis and diode surge simulations that react to your custom curves. A built-in preset browser lets you search local presets by artist, tags, or category, and you can preview and download community-shared presets without an account. Curves are saved as .tfunc files and nest inside system presets. The Harmonic Exciter uses trigonometric identities for precise harmonic control, while Spline and Equation modes offer gesture playback and constant sweeping. It is aimed at hobby producers who want flexible, hands-on distortion shaping without a steep learning curve.
