Vienna Ensemble Pro 7 File Structure

64-bit support

Vienna Ensemble Pro supports hosting of 64-bit VST/VST3/AU plug-ins on a 64-bit server .

On Windows, you may run Vienna Ensemble Pro 64-bit instances side by side.

The most obvious advantage of 64-bit plug-ins when it comes to RAM-intensive applications is of course that with a 64-bit OS you can utilize as much RAM as available.

File Formats and information display

Vienna Ensemble Project (*.vep)

You can save and open separate Vienna Ensemble Pro Projects using the icons in the task bar or by using the Instance menu in Vienna Ensemble Pro.

The saved files are called projects and are saved as *.vep64 files. .vep stands for "Vienna Ensemble Project". A Vienna Ensemble Project (.vep) contains all information saved in a single Vienna Ensemble Pro instance!

When loading a project (*.vep file), the file name will be displayed in [ ] in your Vienna Ensemble Pro Instance Window Title (in this case: "DB_Under_Fire"):

Each Vienna Ensemble Pro Instance is represented by one tab, and the selected instance is highlighted with a small white frame.

The Plug icon shows the connection state of an instance (pale = not connected, white = connected).

The Power button lets you enable and disable an instance.

The Lock icon shows the preserved state (open lock = not preserved, closed lock = preserved).

The Decouple icon shows the Decouple state (pale = coupled, white = decoupled).

You can also label an instance without switching to the preserved status.

If you preserve a newly created instance and name it, e.g., "Strings", this instance name will be displayed in 3 locations.

  1. The Vienna Ensemble Pro Server Instance Tab and 2) the Vienna Ensemble Pro Instance Window Title,

  1. as well as the Vienna Ensemble Pro Server Interface plug-in in your sequencer:

If an instance is connected, it will of course NOT appear in the list of available instances anymore.

The Vienna Ensemble Pro Server will always display the connection status , the name of the instance ,the name of the master computer the Vienna Ensemble Pro Server is connected to (in this case it's the same computer, localhost), and the name of the loaded project (*.vep64).

Vienna Ensemble Server Project (*.vesp)

Once you have set up your template with more than one instance of Vienna Ensemble Pro , you can save a Vienna Ensemble Server Project . Use the File menu to save a Vienna Ensemble Server Project (*.vesp).

A Vienna Ensemble Server Project is a group of Vienna Ensemble Pro instances saved together. It contains the complete information of all Vienna Ensemble Pro instances on the given Vienna Ensemble Pro Server.

Vienna Ensemble Server Project files will be called *.vesp64.

The name of the loaded Vienna Ensemble Server Project will be displayed in [ ] in the Vienna Ensemble Pro Server Window Title.
