Editing Csound (section)

== Csound 5 ==
Version 5.01 was released on March 18, 2006, 20 years after Csound's first release. Csound 5 is available in binary and [[source code]] for [[Linux]], [[Microsoft Windows]], and [[macOS]] from the [[SourceForge]] Csound project.<ref>{{cite web|url=http://sourceforge.net/projects/csound/|title=Csound |website=SourceForge.net}}</ref> It is much improved and expanded compared to the original software, effectively made into a [[software library]] with an application programming interface ([[API]]). A variety of [[Frontend and backend|frontends]] have been developed for it. Beyond the basic [[C (programming language)|C]] API, there are also [[C++]], [[Java (programming language)|Java]], [[Python (programming language)|Python]], [[Lisp (programming language)|Lisp]], and [[Tcl]], among other bindings, like one from [[Haskell]] which allows control of Csound from a purely [[functional programming]] environment.

The use of [[Plug-in (computing)|plug-ins]] allows added abilities without modifying the Csound code, as there is the possibility to write user-defined opcodes as extensions to the original language. Linux Audio Developer's Simple Plugin API ([[LADSPA]]) and [[Disposable Soft Synth Interface]] (DSSI) are supported, but [[Virtual Studio Technology]] (VST) support has been removed.

In the 1990s was added real-time performance via Musical Instrument Digital Interface ([[MIDI]]), and support of Fast Light Toolkit ([[FLTK]]) widgets ([[graphical user interface]] components with sliders, knobs, etc.) to control real-time audio, and integrating custom graphical interfaces written in Python.
