That points to a missing connection to your sample content.

  1. Please make sure that your hard drive is connected correctly.
  2. Check that the your product is visible in your Vienna Assistant.
  3. REPAIR the connection if necessary.


Unfortunately that's not possible. We have restructured so many parameters, that you need a new data format to load sample content in the Synchron Player. When converting the sample content for your SYNCHRON-ized products, we are re-editing many of the samples to perform perfectly within the Synchron Player.

And of course you will always benefit from crossgrade prices when you are switching from your Vienna Instruments Collection to the corresponding SYNCHRON-ized product!

The only restriction for working with the iLok Cloud is that you need to be online to have access to your products.

If you are using a physical iLok key, you only need to be online to download

  • Your licenses onto your ViennaKey
  • The iLok License Manager
  • Your VSL Software and sample content via your Vienna Assistant:

Vienna Assistant Windows

Once these components are installed on your computer, you can go ahead and work even if you're offline.

If you see your CPU Meter in Synchron Player blinking red and the sound is breaking up, your CPU cannot process the audio data you are producing in Synchron Player. Try the following steps to improve the performance:

  1. Increase the buffer size of your sound card.
  2. Increase the Preload size in Synchron Player Settings > Database.
  3. Switch off Velocity XFade, wherever possible.
  4. Reduce the number of used microphones in the mixer.
  5. Lower the voice limit.
  6. Enable “Use Light Convolution” in the Synchron Players Settings > Engine.

If that doesn't help, try to offload some of the notes of the channel to a second Synchron Player instance.

Feel free to install our products on as many computers as you like.

As your licenses are stored in the iLok system, you will be able to work on every computer that has the necessary software components installed.

Physical iLok key: Connect your key containing your licenses with the computer you want to work with.

iLok Cloud: Use the iLok License Manager to log in with your iLok account and activate a cloud session on the computer you want to work with. Each iLok account allows ONE cloud session, so a new log-in will terminate a possibly running cloud session on another computer!

No, the downlaoded files are identical. If your demo license is still active, it will sit next to your permanent license for the remaining days and then expire on it's own.
