ScorchCrafter ~ Guitar FX DAW Plugins


A group of audio DAW plug-ins targeting Windows (VST), Mac (VST/AU), and Linux, mostly for guitar amplifier simulation, with the C-120 being the flagship product (which started off long ago as a closed-source VST). Open source, mostly under GPL.

Features:

  • Up to 128-bit (internal) Multi-Stage Guitar Amplifier Layered Distortion, also runs in 64 and 32 bit modes
  • Native Mac and Linux ports coming soon
  • Advanced maths for tube-like guitar amplifier distortion, doesn’t use cheap waveshaping
  • Designed with dynamic response that changes according to the input level – Much more than just a basic “sample in, sample out”
  • Up to 12x Internal Oversampling, separate controls for live/online and off-line render
  • Multi-Band EQ – low, mid, high, contour, presence
  • Built-in custom convolution-based cab-mic effect, works with almost any sample rate and/or audio buffer size
  • New version of C120 has less clutter in GUI, separate page for advanced features
  • No commercial bloat!
  • GPL license, but just for the plug-in itself
  • Any rendered/processed audio is YOURS (any license you want)!
  • Hand-Coded in C++, pre-fab code or “wizards” were NOT used to build this!
  • Primarily built with MinGW-w64 and Code::Blocks IDE
  • NEW Jykwrakker plugin also features custom stereo reverb FX you won’t find elsewhere.
  • NEW Source code available under zlib license (long overdue)

Protoplug ~ Scriptable Audio Plugins


Create audio plugins on-the-fly with LuaJIT.

Protoplug is a VST/AU plugin that lets you load and edit Lua scripts as audio effects and instruments. The scripts can process audio and MIDI, display their own interface, and use external libraries. Transform any music software into a live coding environment!

Cross-platform: builds for Windows, Mac OS X and Linux. This means that all protoplug scripts are compatible with these platforms and can be loaded into a huge amount of audio software (glory to JUCE).

Fast: Use the speed of LuaJIT, and perform DSP tasks as efficiently as old school C implementations.

Free and open source: Want a new feature? Add it yourself. The source is MIT-licensed and available on Github.
