🕰️ The Evolution of Reason: From Walled Garden to Open Playground


Video: The Updated Guide on How to Use VSTs in Reason (2021 Edition).








Ah, Reason. For those of us at Uniphonic™ who’ve been in the game for a while, we remember the “old days.” For years, Reason was famous for being a beautiful, self-contained “walled garden.” You had everything you needed to make a track right in the box, and it was incredibly stable because it was a closed system. No third-party plugins allowed. This was both its greatest strength and, for some, its most frustrating limitation.

This philosophy was born from a desire to create a virtual studio that behaved like a real one—rock-solid and free of the crashes that often plagued other DAWs dealing with a jungle of third-party code. But as the world of VST plugins exploded with innovation, the pressure mounted. Users wanted to bring their favorite synths like Serum and effects from developers like FabFilter into Reason’s creative workflow.

Then, with the release of Reason 9.5, the walls came tumbling down! 💥 Propellerhead (now Reason Studios) finally introduced VST support, forever changing the game. It was a pivotal moment that transformed Reason from a powerful, self-contained instrument into a full-fledged, open-ended digital audio workstation that could stand toe-to-toe with any other on the market. This evolution continued with the massive update to Reason 12, which officially brought in support for the modern VST3 standard, a move celebrated by the entire community.

✅ Yes, They Do! Understanding Reason’s Third-Party Plugin Support

So, let’s get into the nitty-gritty. How does this all actually work? It’s not just a simple “yes”; it’s a “yes, and here’s how you can make it awesome.” Understanding the different ways Reason handles plugins is key to unlocking your full creative potential.

1. Diving Deep into VST Plugin Integration in Reason

Virtual Studio Technology (VST) is the most widely used plugin standard in the music world. Reason’s adoption of it was a game-changer.

  • VST2 vs. VST3: Initially, Reason supported the VST2 (specifically, VST 2.4) format. While this covered most plugins at the time, the industry was already moving towards VST3. The VST3 format, developed by Steinberg, offers significant advantages, including more efficient CPU usage (plugins only process audio when audio is present), multiple MIDI inputs/outputs, and resizable user interfaces. The update to Reason 12 brought full VST3 support, ensuring compatibility with the latest and greatest plugins for years to come.
  • How it Works in the Rack: When you load a VST plugin in Reason, it appears in its own special “rack device.” This device acts as a host, providing audio inputs and outputs, CV (Control Voltage) connections, and a button to open the plugin’s own graphical interface. This means you can route audio and CV to and from your VSTs just like any native Reason device, opening up insane possibilities for modular-style sound design—a core part of our Music Production Techniques.

2. The Unique World of Reason’s Rack Extensions (REs)

Before VSTs, there were Rack Extensions. Introduced in Reason 6.5, REs are Reason’s proprietary plugin format, and honestly, we still love them.

Feature VST Plugins Rack Extensions (REs)
Source Thousands of third-party developers Developed specifically for Reason, sold in the Reason Shop
Integration Hosted in a VST device wrapper Appear as native Reason devices
Cabling Audio and CV I/O on the host device Fully patchable audio and CV on the back of the rack
Stability Generally good, but can vary by developer Rock-solid, as they are vetted by Reason Studios
CPU Usage Can be heavy, especially older VST2 plugins Highly optimized for the Reason environment
GUI Opens in a separate window Fully integrated into the Reason rack interface

REs feel like they belong in Reason. They are designed from the ground up to work with Reason’s unique patching system. Flipping the rack around (with the Tab key) to route CV from a player like Players Step Note Recorder to the filter cutoff of a synth RE from a developer like U-he is a tactile experience that VSTs can’t quite replicate. It’s a key part of the Hardware vs Software debate, brought to life in your DAW.

3. Installing and Managing Your Third-Party Plugins in Reason

Getting your plugins into Reason is a straightforward process.

Step-by-Step Installation:

  1. Install the Plugin: Run the installer for your VST plugin just as you would for any other DAW. Pay attention to whether you’re installing the VST2 or VST3 version (install both if you can!).
  2. Set Plugin Folders: The first time you run Reason after installing a new VST, it will likely prompt you to scan for plugins. If not, you can manually set this up. Go to Edit > Preferences > Advanced. Here, you can specify the folders where your VST plugins are located.
  3. Scan for Plugins: Reason will scan these folders and make any compatible VSTs available in its browser. If a plugin fails to validate, Reason will disable it to prevent crashes. You can manage and re-enable plugins from the Window > Manage Plugins menu.
  4. Load It Up!: Once scanned, your VST instruments and effects will appear in the Reason Browser under “Instruments” and “Effects,” respectively, usually organized by manufacturer. Drag it into the rack, and you’re ready to make some noise!

4. Integrating Third-Party Instruments and Effects into Your Reason Workflow

This is where the fun begins. Let’s say you want to use the iconic wavetable synth Xfer Records Serum.

  • As an Instrument: Drag Serum from the browser into the rack. Reason automatically creates a Mix Channel for it and routes the MIDI. Now you can play it with your keyboard and sequence it in the main sequencer.
  • With Reason’s Effects: Want to run Serum through Reason’s killer Scream 4 Distortion? Easy! Just create a Scream 4 device and use the auto-routing feature, or flip the rack and patch Serum’s audio output into Scream 4’s input.
  • With Reason’s Players: This is a big one. You can use Reason’s Players (like the Dual Arpeggio or Scales & Chords) to control your VST instruments. Just place the Player device before the VST instrument in the signal chain. Instant inspiration!

5. Optimizing Performance with Third-Party Plugins in Reason

Let’s be real: third-party plugins can be CPU hogs. Here are some pro tips from our audio engineers to keep your sessions running smoothly.

  • Increase Your Buffer Size: In Edit > Preferences > Audio, increase the buffer size. This increases latency but gives your CPU more time to process, reducing clicks and pops. It’s a classic trade-off we discuss in our Performance Techniques articles.
  • Freeze Tracks: If a track with a heavy VST synth is finalized, right-click the track and select “Bounce > Bounce Track in Place.” This converts it to an audio file, freeing up the CPU that the VST was using.
  • Use VST3 Versions: Whenever possible, use the VST3 version of a plugin. Its ability to sleep when no audio is passing through can save a surprising amount of CPU power.
  • Check Plugin Performance: In the Window > Manage Plugins menu, you can see which plugins are using the most CPU. This can help you identify any troublemakers.

6. Troubleshooting Common Third-Party Plugin Issues in Reason

Sometimes, things go wrong. It happens. Here are a few common snags and how to fix them.

  • Plugin Not Showing Up:
    • Did you install the VST version (not AU or AAX)?
    • Is the plugin 64-bit? Reason no longer supports 32-bit plugins.
    • Have you pointed Reason to the correct plugin folder and performed a full scan?
  • Plugin Fails Validation:
    • This usually means the plugin is unstable or incompatible. Check the developer’s website for an updated version. Sometimes, a full re-install of the plugin can fix corrupted files.
  • GUI is Glitchy or Slow:
    • This can be a graphics card issue. Make sure your graphics drivers are up to date. Some plugins also have settings to reduce the graphical intensity of their interface.

7. Beyond VSTs: What About AU and AAX Plugins in Reason?

We mentioned this in the quick tips, but it bears repeating. Reason does not support AU or AAX plugins.

  • Audio Units (AU): This is Apple’s proprietary format, used by Logic Pro X and GarageBand.
  • Avid Audio eXtension (AAX): This is Avid’s format for Pro Tools.

If you have a plugin that is only available in AU or AAX format, you unfortunately won’t be able to use it directly in Reason. However, most major plugin developers release their products in VST, AU, and AAX formats simultaneously, so this is rarely a major issue.

The floodgates are open! Here are a few VSTs that our team at Uniphonic™ absolutely loves using inside Reason. They complement Reason’s native devices beautifully. Check out more of our favorites in our Plugin Recommendations category.

  • Synths:
    • Xfer Records Serum: The undisputed king of wavetable synthesis. Its deep modulation options pair incredibly well with Reason’s CV capabilities.
    • u-he Diva: For those who crave authentic, lush analog synth sounds. It’s a CPU monster, but the sound is worth every cycle.
    • Native Instruments Kontakt: The industry-standard sampler. Essential for realistic acoustic instruments and vast cinematic libraries.
  • Effects:
    • FabFilter Pro-Q 3: A surgeon’s scalpel of an EQ. Its dynamic EQ features are a must-have for modern mixing.
    • Valhalla DSP Reverbs (VintageVerb, Shimmer, etc.): Incredibly high-quality reverbs that won’t break the bank. They sound divine on Reason’s synths.
    • iZotope Ozone: The ultimate mastering suite. Having this in your Reason project’s master section is a massive workflow enhancement.

Alright, let’s get to the real secret sauce. Supporting plugins is one thing; mastering them is another. Here’s some hard-won wisdom from the trenches here at Uniphonic™.

The Great MIDI Out Mystery 🕵️‍♀️

This is one of the most confusing topics for new and old Reason users alike. You’ll see forum posts where one person says “Reason has had MIDI out since Reason 7,” while another claims “Reason does not support MIDI out from VSTs.” So, what’s the deal?

Both statements are technically true, and the distinction is crucial.

  • Reason’s Native MIDI Out: Since Reason 7 (way back in 2013!), the Reason application itself has been able to send MIDI data out to external hardware synths via its “External MIDI Instrument” device. This is a fundamental DAW feature.
  • VST MIDI Out to Reason Devices: The challenge has always been getting a third-party VST plugin to send its MIDI data to control a native Reason device (like the Thor polysonic synthesizer or a Rack Extension). For a long time, this was not directly possible. This is why a plugin like Xfer Records Cthulhu, a brilliant MIDI chord and arp generator, was officially listed as “unsupported.” You could use it to control another VST synth inside Reason, but not Thor. This limitation is similar in spirit to how some other DAWs have specific restrictions, like Cubase’s long-standing lack of support for third-party MIDI insert plugins, a point of frustration for its users for years.

The Modern Workaround (It’s Easier Now!):

Thankfully, the situation has improved dramatically. While direct VST-to-RE MIDI routing isn’t a simple drag-and-drop affair, it’s very achievable with the right tools.

  1. Use a VST Host: You can use a VST host plugin inside Reason to create more complex routing. A fantastic and free option often recommended is Kushview Element.
  2. The Setup: You load Kushview Element as a VST instrument in Reason. Inside Element, you load your MIDI generator (like Cthulhu) and then route its MIDI output to a virtual MIDI port.
  3. Loopback: In Reason’s sequencer, you create a new track for your target Reason device (e.g., Thor) and set its MIDI input to the virtual MIDI port you just created.

Voila! You are now controlling a native Reason synth with a third-party MIDI VST. It sounds more complicated than it is, and once you do it once, it becomes second nature. It’s a powerful technique for combining the best of both worlds.
