There’s 100s of scripts out there that offer the user an efficiency or quality-of-life boost, but here I aim to showcase the scripts that quickly demonstrate what Reaper’s scripting environment is capable of. There’s some scripts out there that surpass anything listed, but they require a bit more time to fully appreciate their power.
All of these scripts are cross-platform and work equally well on macOS and Windows. Most of them work on Linux-based operating systems too.
Note - These videos are shot at 15fps to save bandwidth. The GUIs very often perform much better live.

The world of audio is particularly intriguing for those with limited or no sight. Fortunately OSARA is here to provide a comprehensive set of scripts that make using Reaper with a Screen Reader much easier.
OSARA isn’t just for those with impaired sight. It can make the process of operating Reaper while you’re not looking at your screen a breez.
Every Reaper user should give OSARA a try, and if you know any sight-impaired musicians then they need to know about it.
Radial Menu - Thread
Browsing menus is tedious. Radial Menus makes browsing menus easy. Your own custom selection of actions can be laid out for quick access.
Radial menus has a number of options for how the mouse interacts with the menus and an awesome keyboard shortcut feature. The keyboard shortcuts allow you to have an almost vim-like set of tiered and contextual shortcuts.
LBX Stripper - Thread
LBX Stripper is a system that allows you to create your own custom interfaces for FX chains. If you’re familiar with Logic’s Smart Controls then you have an idea of 1% of what LBX is capable of.
Build your own beautiful GUIs for your FX chains, and more, with LBX Stripper.
CC, Automation and parameter control
Envelope based Compressor v2 - Thread
Envelope-based Compressor v2
Envelope-based compressor is a compressor that applies the amplitude changes to the track’s envelope. This allows you to have a compressor that’s freely editable on a timeline.
If you’ve ever struggled trying to get vocal compression just right by fooling with a series of compressors and automation, then Envelope-based compressor is a godsend.
Envelope based De-Esser - Thread
Envelope-based DeEsser applies frequency-sensitive compression on the track’s envelope. It’s just like Envelope-Based Compressor except the signal is routed through a filter first.
Another amazing script for vocal editing.
LFO Tool - Thread
LFOs. Shaped, mangled, varied and wherever you want them! LFO Tools gives you extreme control over LFO-based automation.
LFO Tools Midi
There’s even a selection of LFO tools for various MIDI-based functions.
Mapping Panel - Thread
Mapping Panel allows you to link together parameters across effects and tracks with optionally complex scaling..
Macro controls on steroids.
Align Takes - Thread
Have you ever tried to record a bunch of takes of vocals to create a chorus part, done dialog replacement or tried to layer some lead guitars, but the end result sounds like a total mess?
Maybe you’d have used Vocalign in the past, but in Reaper you can freely download and use Align Takes!
Align Takes analyzes nearly an unlimited number of audio items, finds the near-similarities between them then intelligently warps the dub track to the reference track. The result: perfectly timed overdubs.
AB Level Matching - Thread
When trying to A/B things it’s important to manage volume levels so that you’re not tricked by the ‘louder is better’ phenomenon.
This can be difficult to manage with complex sessions, tracks and having to setup various routing for realtime A/B. The A/B Level Matching tool makes it easy and offers a number of advanced options for really getting a hold of your A/B sessions.
Stretch Marker Guard - Thread
Stretch Marker Guard
When using stretch markers naively, the transient is stretched as much as the rest of the sound. For things like percussion it’s important that the impact of the sound be retained, and stretch marker guard allows you to do this will still warping your hits in to place.
Stretch marker guard easily allows you to place new stretch markers around the existing markers, either before, after or both. This makes it so that when stretching, the transient is guarded from an extreme stretch. Since stretch markers only affect the area between markers, the transient is given its own small area where minimum stretch occurs, and then the rest of the movement ideally happens during the sustain of the sound.
This is an exceptionally useful tool and can make a huge difference in the impact and fidelity of your drum sounds.
Articulation Manager - Thread
Articulations are a concept that allows you to trigger specific performance-related attributes in a synth or sampler. They can be very complex to manage, especially for large projects.
Articulation Manager may not make working with articulations easy (nothing can), but it makes it as pain-free as possible.
Midi Editor Tools - Thread
So many MIDI tools
juliansader’s huge selection of midi tools is indispensible. I can not even begin to describe them. Click the title above to browse the thread and see all the amazing things you can do to manipulate MIDI with this selection of Scripts.
Quantize Tool - Thread
Have you ever wanted to quantize your stretch markers to midi? Midi to envelope points? Item starts to midi? How about any combination of those and much more
You can quantize Items, Stretch Markers, Envelope points and Midi Notes to: Items, Stretch Markers, Envelope points, Notes, Grooves, Grid, and swing grid. All of these with a wide range of options and a %-based-amount to tweak the result to perfection.
Oh yeah, and it all happens live as you change parameters!
This isn’t just a MIDI tool. It’s an ‘everything in its right place’ tool.
ReaTab Hero - Homepage
How many DAWs do you know that have proper tablature built in? What about with wonderful graphics and a ‘guitar hero’ style display.
Watch the video. ReaTab Hero is amazing.
Super Arpeggiator - Thread
Take your midi and arpeggiate or sequence it however you want. Super Arpeggiator lives up to its name.
Arp!0 Arpeggiator - Thread
Yet another fantastic argeggiator. Highly variable sequenceable steps, a smooth easy to operate GUI with a lot of information and loads of fun.
Arp!0 sets the bar for what an arpeggiator can be. Free, in Reaper.
Reaticulate - Website
Articulations are ways of varying performance attributes when using large and complex multi-sample libraries, often Orchestral libraries. Articulations are usually triggered via keyswitches (and the terms are often used interchangeably). Keyswitches are usually specific midi notes, that exist outside the range of the instrument, that are used to change the current performance characteristics of the instrument. Keyswitches can also be CC or program change as well.
As you can imagine, managing this data can be problematic, and very few DAWs have solutions to this problem. Enter Reaticulate.
Reaticulate gives you a simple GUI for managing articulation data in your MIDI based performances. I suggest watching the video above to get a better idea of what Reaticulate offers. If you are someone that often uses large orchestral libraries then I think you will be very pleased.
Playtime - Thread
Reaper users can have it too with Playtime, but with all the features and capabilities that Reaper offers along-side it.
Midi Guitar Chord Tool - Thread
MIDI Guitar Chord Tool
Guitars are peculiar instruments in that the chord forms differ greatly from the piano that most of us use to input MIDI. A big part of creating authentic sounding guitar parts is getting the chord shapes correct.
Enter MIDI Guitar Chord Tool. It allows you to quickly enter common guitar chord voicings, inversions and add strumming.
It’s not just for guitar either. It works fantastic for creating thick synth chords or a beginning for various forms of composition.
Theory helper - Thread
Explore scales and chords with Lokasenna’s Theory Helper. Strongly suggested to supplement with ZappaDave’s Ultimate ReaScale
Orchestral Template - Homepage
Orchestral composition can be tedious. Hundreds of tracks, thousands upon hundreds of thousands of events. Nearly unmanagable amounts of automation and MIDI CC.
Except, it can be easy. OTR brings together a comprehensive set of workflows for the monumental task of modern orchestral composition. Check out the video series. There’s features here that no other DAW can compare with.
Shuffle Items - Thread
Layering items for creating sound effects or more powerful musical samples is a common task these days. Often a designer will want to create a variance of items to create interest and have an arsenal of sounds to use later.
ExtremRaym’s shuffle items scrips let you do this. You set your snap offsets for the layers, laid across tracks, then you can shuffle the layers around to create new variations. Very useful.
Not only that, but you can simply shift around each column. This allows you to move around layers, but maintain the same layer composition.
That’s not all. Check out the thread for even more great layering and item organization scripts!
RS5K Manager - Thread
RS5K Manager is an integrated browser and step sequencer for using Reaper’s SamplOmatic5000. It allows you to store directories for quick recall, quickly map samples to new instances of SamplOmatic5000 on the selected track while set to the assigned note.
From there it includes a simple step sequencer for writing midi to the currently selected item, or optionally the ability to drop in references to the current sample as an audio item on a child track.
RS5K manager isn’t exactly a powerhouse, but it is a great shortcut to getting started on a track. It’s also another awesome example of what can be done with ReaScripts.
Synths & Effects
ReaRack Modular - Thread
A modular synth in Reaper that’s fully extendable in via JSFX. ReaRack offers a selection of modules that can be linked together in creative ways to create a monster digital modular synth.
Since it can get quite complex, it includes some example projects to show how things can be done.
Sonic Anomaly - Homepage
Sonic Anomaly plugins
Sonic Anomaly has made a selection of fantastic and unique plug-ins with great GUIs for Reaper. Many of the plug-ins offer functions and quality-of-sound that are only available elsewhere for a large cash layout.
A must-have for every Reaper user.
Geraint’s JSFX - Homepage
Yes another selection of fantastic jsfx plugins. Even more plugins that you’d pay big money for elsewhere like a spectrum mapper, pad synth, harmonizer and more.
Be sure to check out the homepage for more information on the effects/synths.
Another must-have for every Reaper user.
Ambisonic Toolkit - Homepage
Ambisonics may not be for everyone, but if you’re in to it then you’re ready to work natively in Reaper with the Ambisonic Toolkit.
gfxanalyzer - Thread
Multi-channel graphic analyzer
Veto_gfxanalyzer is a multi-channel analyzer. You can route multiple tracks to it and the spectrum of the tracks are overlaid.
Use is simple after installation. You insert Veto_gfxanalyzer.jsfx on a track. Route the tracks you want to that track with the routings of 1/2->1/2, 1/2->3/4, 1/2->5/6 etc… incrementing the destination channel each time. This means you’re sending audio to a different channel on the same track, and gfxanalyzer reads those channels.
You can also assign the track colours to the analyzer output by selecting the Veto_gfxanalyzer window and running the
Script: Set colors of focused Veto_gfxanalyzer to tracks sending on channels 1-16.eel script.
Very cool and free script!
FXRack - Thread
The bottom graphic above is FXRack. The top is the exact same setup in TrackFX Routing. There is a pre-fx section that is split in to rows of effects chains. There’s 8 parallel effects changes that are then summed to the post-fx stage.
Instruments and effects can be used, and mixed as desired. Each parallel effects chain has pre-gain, post-gain, post-pain, solo and polarity inversion.
This is really an awesome script that exposes Reaper’s built-in functionality that provides you essentially a free Bluecat Patchwork.
TrackFX Routing - Thread
Track FX Routing
Routing in Reaper is very powerful. It can also be very confusing at times, but with this script you can easily manage your routing and track FX.
Once you find out what you can do with Reaper’s Routing then this script will brighten your day.
LBX Chaos Engine - Thread
LBX Chaos Engine
LBX Chaos Engine is an amazing script that allows you to morph between settings, sequence changes, randomize parameters and more. Ever wanted to slowly morph between 2 reverb sounds? Have a lead morph to a bass? Control a vast variety of parameters as a vocal crescendos in to a bridge? LBX Chaos Engine makes it easy!
It’s fairly simple to setup if you follow the Readme.md included.
In the video above you can see me effortlessly morphing between 2 presets and a randomized preset in Repro-5.
Project to HTML or CSV - Homepage
Sound designers, foley artists, dialog recorders, sampling maniacs, composers and more often need a way to export metadata of their project to other formats for logging and other tasks.
This script allows you to easily export things like item names, position, length, colour, status, FX metadata and much more… to HTML or CSV for easy viewing and logging.
The HTML export outputs a beautiful table of data for easy browsing. A really amazing tool for a number of workflows.
Advanced Tempo Tool - Thread
Advanced Tempo Tool
Advanced Tempo Tool allows you to create complex tempo maps with ease. Often the process of changing tempos/time signatures can be a tedious hair-pulling experience, but ATT lets you keep that hair.
Creating complex time signature changes and tempo changes (which Reaper optionally will stretch item times or stretch the items themselves to) becomes a fun task.
ReaNoir - Thread
Colours. Colours everywhere! Organize your projects in style using a variety of stylized palletes of your own design or choosing.
ReaNoire makes the colour-coding of your projects easy.
Track-Item Manipulation - Thread
Track-Item Name Manipulation
Renaming tracks is time consuming. Renaming items is a horrifying experience. What if you could easily manipulate the names of tracks and items without sacrificing your lifespan?
Track/Item Manipulation let’s you do that. Select your tracks or items and easily batch adjust the naming to what you need.
Track lists - Thread
Reaper does offer Takes and Comps, but sometimes you want to have alternate edits or compositions or even recordings.
Sexan’s Track List script allows you to easily create, modify and save various edits of a track for easy recall.
Super 8 is included in Reaper. It’s an 8-track looping tool similar to you may find in a guitar looping pedal.
Super 8 is one of my favorite parts of Reaper. You can use it to build a phrase of a track, a whole track or just have fun layering things. Watch the video above to get a feel for what is possible.
Super 8 is so much fun.
