VST (Virtual Studio Technology)

Steinberg’s Virtual Studio Technology (VST) is an interface for integrating software audio synthesizer and effect plugins with audio editors and hard-disk recording systems. VST and similar technologies use Digital Signal Processing to simulate traditional recording studio hardware with software. Thousands of plugins exist, both commercial and freeware, and VST is supported by a large number of audio applications. The technology can be licensed from its creator, Steinberg.

VST plugins are generally run within a Digital Audio Workstation, providing the host application with additional functionality. Most VST plugins can be classified as either instruments (VSTi) or effects, although other categories exist. VST plugins generally provide a custom GUI, displaying controls similar to the physical switches and knobs on audio hardware. Some (often older) plugins rely on the host application for their UI.
VST instruments include software simulation emulations of well-known hardware synthesizer devices and samplers, emulating the look of the original equipment and its sonic characteristics. This enables VSTi users to use virtual versions of devices that may be otherwise difficult to obtain.
VST instruments require notes to be sent via MIDI in order to output audio, while effect plugins process audio data (some effect plugins do require a MIDI input too though, for example they might use MIDI sync to modulate the effect in sync with the tempo). MIDI messages can often also be used to control parameters of both instrument and effect plugins. Most host applications allow the audio output from one VST to be routed to the audio input of another VST (known as chaining). For example, output of a VST synthesizer can be sent to a VST reverb effect for further processing.

The VST interface specification and SDK was released in 1996. Coinciding was the release of Steinberg Cubase 3.02. Included with Cubase were the first available VST format plugins. Espacial, Choirus, Stereo Echo and Auto-Panner.[1]
The VST interface specification was updated to version 2.0 in 1999. One of the additions was the ability for plugins to receive MIDI data. This allowed for the introduction of VSTi (Virtual Studio Technology Instrument) format plugins. VST Instruments can act as standalone software synthesizers, samplers or drum machines.[2]
Neon[3] was the first available VST Instrument (included with Cubase VST 3.7). It was a 16-voice, 2-oscillator virtual analog synthesizer.[4]
The VST interface specification was updated to version 2.4 in 1999. Changes included the ability to process audio using 64 bit precision.[5]
The VST interface specification was updated to version 3.0 in 2008. Changes included:[6]
Audio Inputs for VST Instruments
Multiple MIDI inputs/outputs
Optional SKI (Steinberg Kernel Interface) integration
[edit]VST plugins

There are three types of VST plugin.
VST instruments generate audio. They are generally either virtual synthesizers or samplers. Some, such as Native Instruments’ Pro-53, specifically recreate the look and sound of famous synthesizers from years past (in this case, the Prophet-5).
VST effects, such as reverb and phaser effects, process audio input. Other monitoring effects provide visual feedback of the input signal without processing the audio. Most hosts allow multiple effects to be chained.
VST MIDI effects process MIDI messages prior to routing the MIDI data to other VST instruments or hardware devices; for example, to transpose or create arpeggios.
[edit]VST hosts

A VST host is a software application or hardware device that allows VST plugins to be loaded and controlled. The host application is responsible for handling the routing of digital audio and MIDI to and from the VST plugins.
There is a wide range of VST hosts available, including the following:
Ableton Live
Adobe Audition
Adobe Premiere Elements
Adobe Premiere Pro
Steinberg Cubase
Steinberg Nuendo
FL Studio
There are also stand-alone “dedicated hosts” whose sole purpose is to serve as a host for the VST plugins rather than as an extension of their sequencing or audio capabilities. These are usually optimized for live performance use, with features like fast song configuration switching. Examples of popular dedicated VST host software include:
Brainspawn Forte
Tobybear MiniHost
VST plugins can be hosted in incompatible environments using a translation layer, or shim. For example, FL Studio fundamentally supports only its own internal plugin architecture, but a native “wrapper” plugin exists that can, in turn, load VST plugins, among others. As another example, FXpansion offers a VST to RTAS (Real Time AudioSuite) wrapper (allowing VST plugins to be hosted in the popular Pro Tools digital audio workstation), and a VST to Audio Units wrapper (allowing VST plugins to be hosted in Apple Logic Pro Digital Audio Workstation).
Hardware VST hosts can load special versions of VST plugins. These units are portable and usable without a computer, although all editing is done on a computer. Other hardware options include PCI/PCIe cards designed for audio processing, which take over audio processing from the computer’s CPU and free up RAM. Examples of hardware VST hosts are RECEPTOR (Muse), Plugzilla and V-Machine (SM Pro Audio).
Audio data can also be sent over a network using appropriate software, allowing the main host to run on one computer and VST plugins to run on peripheral computers.
[edit]VST plugin standard
The VST plugin standard is the audio plugin standard created by Steinberg to allow any third party developers to create VST plugins for use within VST host applications. VST requires separate installations for Windows, Mac OS X and Linux. The majority of VST plugins are available for Windows due to both Apple’s proprietary Audio Unit software for OS X and the lack of information and patent encumbrances that make development difficult for Linux platforms.

VST plugins often have many controls, and therefore need a method of managing presets (sets of control settings).
Steinberg Cubase VST introduced two file formats for storing presets: an FXP file stores a single preset, while an FXB file stores a whole bank of presets. These formats have since been adopted by many other VST hosts, although Cubase itself switched to a new system of preset management with Cubase 4.0.
Many VST plugins have their own method of loading and saving presets, which do not necessarily use the standard FXP/FXB formats.

[edit]Programming languages

Steinberg’s VST SDK is a set of C++ classes based around an underlying C API. The SDK can be downloaded from their website.
There are several ports available, such as a Delphi version by Frederic Vanmol, a Java version from the jVSTwRapper project at sourceforge.net, and a .NET version – Noise. Another .NET implementation is VST.NET. This open source project also includes a framework which makes creating VST plugins easier and result in more structured code. VST.NET also provides support for writing managed host applications with a managed class that allows loading an unmanaged Plugin. A notable language supporting VST is Faust considering that it is especially made for making signal processing plugins, often producing code faster than hand-written C++.
In addition, Steinberg have developed the VST GUI, which is another set of C++ classes, which can be used to build a graphical interface. There are classes for buttons, sliders and displays etc. Note that these are low level C++ classes and the look and feel still have to be created by the plugin manufacturer.
A large number of commercial and open-source VSTs are written using the JUCE C++ framework instead of direct calls to the VST SDK, because this allows multi-format (VST, AudioUnit and Real Time AudioSuite) binaries to be built from a single codebase.
