What EFEKTOR GrandMaster does
The plugin groups three overdrive and distortion types under one interface, named Drive, Gvnr and Shred, each modeled on an authentic British sound as the developer describes it. Oversampling reaches up to 8 times, and a dry/wet control sets the balance between the original signal and the processed sound.
Formats are VST3, VST2, AU and AAX for Windows and macOS, with native support for Apple Silicon listed. Pro Tools is the host the developer names. The window can be resized, and the plugin can also be loaded as a module inside Amplifikation 360.
Key features
- Three British overdrive types. Drive, Gvnr and Shred are the three voicings, each covering a different overdrive or distortion character.
- Up to 8x oversampling. Oversampling can be raised up to 8 times to keep the processed signal smooth at high drive settings.
- Dry/wet control. A dry/wet control lets the original signal be blended with the affected sound in any proportion.
- Resizable window. The interface window can be resized to suit the screen space and workflow of the user.
- Single-screen interface. All controls sit on one screen, so the overdrive and distortion settings can be dialed without switching pages.
- Amplifikation 360 module. The plugin is available as a module for Amplifikation 360, placing it inside that environment.
Compatibility
Available as VST3, VST2, AU and AAX for Windows 7 and later and macOS 10.11 and later, 64-bit, with native Apple Silicon support listed.
