# Scripter Overview

<Note>
  Articles about the Scripter plug-in and scripts are intended for advanced users who are developing their own MainStage programming.
</Note>

The [Scripter plug-in](https://support.apple.com/guide/mainstage/use-scripter-lgce728c68f6/mac) significantly expands the functionality of MainStage and Logic Pro by allowing you to create and run custom scripts. These JavaScript-flavored scripts can manipulate MIDI, and behave like any other plug-in in your concert.

MagicFox is pleased to [provide several scripts](https://magicfox.co/pages/mainstage-scripts). These scripts are freely distributed for personal, non-commercial use. Please [contact us](https://magicfox.co/pages/contact) to inquire about purchasing a license for commercial use.

## Installing scripts

The typical steps for installing a script in MainStage are as follows:

<Steps>
  <Step title="Download and uncompress the archive.">
    Scripts are saved as **.pst** files. To ensure successful downloads, we compress our scripts into a .zip archive.
  </Step>

  <Step title="Move .pst file">
    Move the **.pst** file to this folder on your computer: `(your username)/Music/Audio Music Apps/Plug-In Settings/Scripter`.
  </Step>

  <Step title="Add the Scripter plug-in">
    Click the **MIDI FX** button on a channel strip (e.g., a harp channel strip) and choose **Scripter**. The Scripter plug-in will open.
