# VST:n ja VSTi:n käyttö

## Introduction to VST

Virtual Studio Technology (**VST**) is an audio plug-in software interface licensed under Steinberg that integrates software synthesizers and effects units into digital audio workstations. Most VST plugins are either instruments (VSTi) or effects (VSTfx). VSTi includes software simulation emulations of well-known hardware synthesizers and samplers.

## Installing VSTs

In MuseScore Studio 4, any compatible VST plugins installed on a **Windows** or **MacOS** computer will automatically be made available in the [Mixer](https://handbook.musescore.org/fi/sound-and-playback/mixer), where you can easily configure playback settings for all instruments in a score.

Since version 4.6.0, VST3 support has also been enabled for **Linux**.

{% hint style="info" %}
Since VST3 support for Linux is relatively new to MuseScore Studio, not all plugins may work as expected. If a particular instrument or effect doesn't work on your system, it may be due to an issue specific to that plugin. In most cases, it's best to raise an issue in our \[issue tracker]\(<https://github.com/musescore/MuseScore/issues>) so we can triage it for investigation.
{% endhint %}

After installing new VSTs on your computer, you may have to restart MuseScore to make them visible in the mixer. If this doesn't work, you can *force* a re-scan of VSTs by deleting previous cache settings before restarting. On Windows the relevant file can be found at:

`C:\Users\[username]\AppData\Local\MuseScore\MuseScore4\known_audio_plugins.json`

MuseScore 4 tukee suoraan *vain* VST3-liitännäisiä (ei VST1- tai VST2-versioita) lisenssirajoitusten vuoksi. Jos käytössäsi on VST1- tai VST2-liitännäisiä, katso ohje: [Kuinka käyttää vanhempia, muita kuin VST3-liitännäisiä MuseScore 4:ssä](https://musescore.org/en/node/352231).

{% hint style="info" %}
Sound settings in the \[Mixer]\(mixer.md) are saved with the score, but not to the program.
