Vienna Ensemble Pro 6 is a mixing and hosting application designed to reduce the load on a DAW. It manages instruments and effects in a separate process, offers CPU efficiency and plug-in format flexibility, and can distribute work across multiple computers. Its VST, AU and AAX support and ability to host 32-bit plug-ins make it useful in large production setups.
Run instruments and effects outside your DAW

In response to many requests, we will explore Vienna Ensemble Pro 6.
This mixing and hosting application lets you load and manage software instruments and effects outside your DAW.

Benefits of Vienna Ensemble Pro 6
First, let’s look at the benefits of using Vienna Ensemble Pro 6.
Use plug-ins across formats

Vienna Ensemble Pro 6 supports AAX, AU and VST, so it can be opened in a range of DAWs.
It can then host VST and AU plug-ins (AU on Mac only) on behalf of the DAW.
With Vienna Ensemble Pro 6 as an intermediary, you can use VST plug-ins in Logic or AU/VST plug-ins in Pro Tools, working across plug-in format boundaries.
It can also load 32-bit plug-ins, allowing you to use 32-bit plug-ins in a 64-bit DAW.
CPU efficiency

Running instruments and plug-ins in Vienna Ensemble Pro 6 can offer more favorable CPU usage than loading instruments directly in the DAW.
The software also includes a freeze function to reduce instrument load.
Distribute CPU load over a network

Connecting multiple computers to the same network lets you distribute the CPU load of instrument and effect processing.
For example, you can dedicate a powerful desktop computer to instruments and effects while using a portable laptop as the main computer running your DAW.
Switch DAWs or songs without reloading instruments

Vienna Ensemble Pro 6 can run independently of the DAW song.
This can greatly reduce instrument loading times when opening or switching songs and improve workflow.
Launching Vienna Ensemble Pro 6

After installation, look in:
- Mac: Applications folder
- Windows: Program Files
The folder is named “Vienna Ensemble Pro”.

The application used to connect with the DAW is Vienna Ensemble Pro Server.
Items labeled “(64bit)” handle 64-bit plug-ins; those without the label handle 32-bit plug-ins.
Here we will use the 64-bit version. Double-click it to launch.
The first launch scans VST plug-ins and may take some time.
As a rule, always launch it before starting your DAW.

The DAW and Vienna Ensemble Pro Server therefore run as separate applications.
Next time we will explain how to connect them.
