Craft your own effects and instruments

Blue CatAudio's Plug'n Script is an audio and MIDI scripting plug-in that can be programmed to build custom effects or virtual instruments, without quitting your favorite DAW software.

With this plug-in, you can write your own plug-in with very little knowledge about programming. If you do not care about programming, Blue Cat's Plug'n Script can also be used as a regular multi effects processor with existing scripts or to get someone else write this very particular utility you have been searching for years and cannot find anywhere.

If you are an experienced programmer, you will find in Plug'n Script a powerful development environment for audio plug-ins: prototype algorithms quickly, generate a state of the art graphical user interface (GUI) without a single line of code, and export a VST, VST3 or Audio Unit plug-in, right from within your favorite DAW! Creating a plug-in has never been so fast!

This plug-in has been in Blue Cat Audio's lab for several years and has been used to prototype lots of their existing plug-ins. It supports both scripts distributed as source code and pre-compiled binary scripts.

For source scripts, it uses the high performance AngelScript scripting engine, originally developed for video games, with a JIT compiler that helps compiling scripts into machine code for optimal performance. Starting with version 2, the plug-in also supports native (compiled) code and can load binary scripts built from C or C++ (or any language that can export C functions, such as Delphi, Fortran, .Net...), using the same interface as the angelscript version.

The syntax of the AngelScript language is close to Java, C#, C++ or JavaScript, making it very easy to learn. It is also convenient to reuse your scripts into native code, or integrate code snippets found on the web into your script. Also, switching between angelscript and binary versions of the same script is very easy, requiring very few changes.

The plug-in includes dozens of audio and MIDI processing scripts as well as several virtual instruments and utilities to enhance your workflow. They can be used as is, or as examples to get started to write your own scripts. User scripts can be shared in the scripts repository, which also includes the factory scripts and native projects for reference.

To build complex effects chains using multiple scripts, you might be interested in Blue Cat's PatchWork, which can host multiple instances of this plug-in in series or parallel. While writing scripts, you might also want to use the analysis tools to check their effect on the signal.

Main Features :

• Audio and MIDI scripting plug-in.
• Build your own Audio and MIDI effects or virtual instruments.
• Export your effect or instrument as an independent VST, VST3, Audio Unit or AAX plug-in.
• Simple scripting syntax, using either the AngelScript language (similar to C++, Java or javascript) or C/C++ for native code.
• Native binary scripts support (compiled C, C++ or Delphi, Fortran...).
• Fully customizable user interface that adapts to scripts automatically. Build your own using Blue Cat's KUIML language.
• Up to 48 input parameters and 32 outputs, with full MIDI and automation control.
• Use your favorite Integrated Development Environment (IDE) for editing.
• Integrated JIT (Just In Time) compiler for optimal performance (scripts are not interpreted but compiled).
• Includes 57 scripts with source code and 267 presets for sound synthesis, MIDI FX, audio FX (comp, gate, tremolo echo, filters, looper...), waveform generation, file playback/recording and more.
• Side chain input and auxiliary outputs support.
• Surround support (up to 8 audio channels).
• Download free scripts from the audio & MIDI scripts repository.
