    All scripts come with a free 14-day trial. In order to start the trial, follow the instructions below to install the script and leave the license key field blank when prompted.


    In order to install this script you will need to first install ReaPack. It's an amazing way for people to easily share REAPER scripts with other users and will allow for this script and all other scripts to be easily updated from within REAPER. For more info on how to use ReaPack go here.

    ReaPack Repository: https://nvk.tools/index.xml

    1. With ReaPack installed, select Extensions-ReaPack-Import repositories and paste the ReaPack Repository url above.
    2. Locate the scripts to install by selecting Extensions-ReaPack-Browse packages and searching 'nvk'. Then you can select the scripts "nvk_FOLDER_ITEMS", "nvk_TAKES", and "nvk_SUBPROJECT" and install them with Actions-Install and then Apply If you haven't already, you should also install "js_ReaScript API" which can be found in ReaPack as well.
    3. After you finish downloading the scripts, you can find them in your actions list by searching 'nvk'

    Note: If you would like to automatically stay up to date with this and other ReaPack Repositories, you can select Extensions-ReaPack-Manage repositories and then Options-Install new packages when synchronizing. Then, when you select Extensions-ReaPack->Synchronize packages it will automatically install all new scripts.


    Install ReaImgui from the ReaTeam Extensions Repository. This repository is included with ReaPack by default so you should have it already. The instructions are the same as installing the main script, just make sure you have the repository enabled, search for 'ReaImgui' in ReaPack and install it.

    js_ReaScript API

    Install js_ReaScript API from the ReaTeam Extensions Repository. This repository is included with ReaPack by default so you should have it already. The instructions are the same as installing the main script, just make sure you have the repository enabled, search for 'js_ReaScript API' in ReaPack and install it.

    SWS/S&M Extension

    Download SWS/S&M Extension and follow the instructions to install

    Activating the License Key

    Once you have the script installed, load your actions list and search "nvk" to locate the script. Double-click it or assign it to a hotkey and run the script. You will be prompted to input your license key, which you should have recieved immediately after purchasing the script.

    This script is only guaranteed to work on the latest version of REAPER and SWS/S&M 64-bit. 32-bit is not supported. Make sure you are up to date before contacting support.



    nvk_WORKFLOW is a collection of scripts for REAPER designed for extremely fast game audio workflows. It comes with three different sets of scripts that all work together

    nvk_FOLDER_ITEMS: Organize your projects with folder items: blank items which represent groups of items in a folder. These scripts allow for quick manipulation, renaming, and rendering of your assets with very little work on your end.

    nvk_TAKES: Embed take markers in your assets that have more than one variation, allowing you to quickly shuffle through variations.

    nvk_SUBPROJECT: A true swiss-army knife of a script. Create subprojects from either selected items or tracks, automatically trim and rename the variations, and re-render them from your main project with automatically generated start and end markers. Makes subprojects incredibly easy to incorporate in your projects by doing all the manual work for you.

    Folder Items


    To get started with folder items, run the script nvk_FOLDER_ITEMS. This script will automatically create folder items that match the length of items inside any folder in your project. You can then use the other scripts to manipulate these folder items. It's recommended to add this script as a startup action so that it runs every time you open Reaper. You could also add it to your toolbar or assign it to a hotkey so you can toggle it on and off.

    nvk_FOLDER_ITEMS - Settings

    This script allows you to customize the behavior of the other scripts in the FOLDER_ITEMS collection. If you create a new preset, the current preset will be saved with the project, so you can have different settings for different types of projects and they will be loaded automatically when you open the project.

    Which script should I use to create Folder Items?

    While nvk_FOLDER_ITEMS is the recommended way to create folder items, there are a couple of other options that might work for your specific workflow. Let's go over them:

    nvk_FOLDER_ITEMS: This script updates the folder items of the entire project each time you make a change. It creates markers and regions if you have those enabled. It also does things like automatically selecting children items when you select a folder item and in the future automatically selected tracks when you select items (just added this). It uses the settings in "nvk_FOLDER_ITEMS - Settings" to determine what to do. It's the most advanced of the 3 scripts the recommended one to use.

    nvk_FOLDER_ITEMS - Update (Manual): This script is the same as the above script except it doesn't automatically update the folder items. You have to run it manually. Recommended for use on extremely large projects where you might have performance issues with the automatic updating. It also doesn't have the automatic selection features but if you still want those you can have nvk_FOLDER_ITEMS running uncheck the Folder Items -> Enable checkbox in the settings.

    nvk_FOLDER_ITEMS - Add new items to existing folder: This is the most minimal script. It only adds new items to the folder track you have selected or the parent track of the items you have selected. If you have a time selection and no items selected it will only create folder items in the parent track that are within the time selection. If you use this, it can work well as either a hotkey or a track double-click mouse modifier. It doesn't create markers and isn't aware of item numbers outside of the current selection. Recommended if you want full control over where your folder items are created and want to keep your project as tidy as possible.



    With version 2 of nvk_WORKFLOW, nvk_TAKES is now a script which runs in the background similar to nvk_FOLDER_ITEMS. It's recommended to add this script as a startup action so that it runs every time you open Reaper. You could also add it to your toolbar or assign it to a hotkey so you can toggle it on and off. While the script is running, take markers will be automatically added to the first selected item in your project. This means that when you import items into your project, you can immediately start using the take markers without having to run the script again. You can then use these take markers to quickly cycle through variations of your assets.

    Essential scripts

    nvk_TAKES: as mentioned above, this script runs in the background and automatically adds take markers to the first selected item in your project.

    nvk_TAKES - Select previous/next take SMART: this script will either move the item contents to the previous/next take marker or if there are no take markers, it will go to the next take. If there are no more takes, then it will go to the start of the first take or the end of the last take depending on which direction you are going. This is the recommended way to shuffle through takes.

    nvk_TAKES - Duplicate items and select next take SMART: this script does exactly what it says, it's great for quickly making variations of a sound.

    nvk_TAKES - Reverse: this is an improved version of the built-in reverse action that works better with the take markers workflow. It preserves the take marker positions and also works with multiple items selected. It's recommended to use this instead of the built-in reverse action.



    To use nvk_SUBPROJECT, select the items or tracks you want to create subprojects from and run the script. It will create a subproject for each item or track and automatically trim and rename the variations. While inside the subproject, you can run the script with no items selected and it will automatically fix the start and end markers. If you have your subproject selected from the main project, it will re-render the subproject and automatically split your items for you.

    nvk_SUBPROJECT - Settings

    Hopefully coming soon, this will allow you to customize the behavior of the script. For now, you can edit the script directly to change the settings.

    Known Issues

  • New hidden tracks setting in Reaper 7 can cause issues with certain scripts (if you find any report them)
  • With hidden tracks setting, grouping must be enabled with the setting selecting one item in the group selects them all or else folder items will not move items in hidden tracks.

  • Big names setting doesn't make folder items name very big on retina displays
  • Changelog
