guitarix is a virtual guitar amplifier for Linux running on Jack Audio Connection Kit. guitarix takes the signal from your guitar as any real amp would do: as a mono-signal from your sound card. The input is processed by a main amp and a rack-section. Both can be routed separately and deliver a processed stereo-signal via Jack. You may fill the rack with effects from more than 25 built-in modules including stuff from a simple noise gate to brain-slashing modulation f/x like flanger, phaser or auto-wah.

This package contains Purr Data, which is a fork of Pure Data that bundles a lot of useful extensions, and brings a modern HTML5-based user interface.Pure Data is an open source visual programming environment that runs on anything from personal computers to embedded devices (ie Raspberry Pi) and smartphones (via libpd, DroidParty (Android), and PdParty (iOS). It is a major branch of the family of patcher programming languages known as Max (Max/FTS, ISPW Max, Max/MSP, etc), originally developed by Miller Puckette at IRCAM.Pd enables musicians, visual artists, performers, researchers, and developers to create software graphically without writing lines of code. Pd can be used to process and generate sound, video, 2D/3D graphics, and interface sensors, input devices, and MIDI. Pd can easily work over local and remote networks to integrate wearable technology, motor systems, lighting rigs, and other equipment. It is suitable for learning basic multimedia processing and visual programming methods as well as for realizing complex systems for large-scale projects.
