Hi Noah,

I am sorry to say that Logic does not support freezing of multi-output multi-instruments by design - only tracks holding the stereo version of the Vienna Ensemble plug-in can be frozen.

It is not necessary to freeze tracks before you bounce them though!

Hi benjohnson2001,

The GM patches are just a subset of samples that are also contained in other Vienna Jazz Drums patches.

Best, Marnix

Hi Ben,

Generally, it is not recommended to use a single sample if it is supposed to sound natural...

The Jazz Drums were in fact designed to be loaded into Vienna Ensemble with the provided Jazz Drums projects from https://www.vsl.co.at/en/MyVSL/MyDownloads/Tutorials_Templates as described in the Jazz Drums manual, which can be found at https://www.vsl.info/en/instruments/vienna-instruments/collections#percussion

The patches in the JD_Cymbals_Brushes Matrix are actually not tempo-synched, but rather controlled by the speed you are playing. The idea behind that is that a cymbal sounds differently if it has already been hit before, depending on how long ago the last hit was. The Vienna Instruments player analyses when the last hit has occurred (i.e. the speed at which you are playing) and plays back the appropriate patch accordingly.

I hope that helps.

Hi Goldstein,

I am afraid that merging channels is indeed not possible in an VE Pro instance.

The only thing you could do is to manually load your various Kontakt patches into one Kontakt multi-instrument and create outputs accordingly, then set the MIDI Input channel to All and create corresponding Aux Input channels in VE Pro.

Hi jdk90026,

I am not sure I understand your Buss/Aux routing - would you please send a simple(!) example PT project to so I can better look into this?

Hi J.Dnp,

I have just replied to your support request Case 402258 (from last Friday...)

It had indeed been caught by our spam filter - my apologies for the delay!

Best, Marnix

Hi,

It is crucial to check "Make this your default configuration" after setting up Kontakt outputs (please see screenshot), then save your project and restart VE Pro - this should resolve your problem!

Hi Zaffer,

I can see on the Steinberg License Transfer Server that you have actually NOT yet downloaded your license for RoomPack 6 to your USB-eLicenser - please do so by entering the corresponding activation code manually in the eLicenser Control Center!

You can select the download destination in the Download Manager.

But no matter where you have downloaded the RoomPack data to, you can select where to INSTALL the files to during the actual installation process!

Hi Taylor,

You may need to delete your AU cache file first, which will force Logic to re-scan for plug-ins the next time you launch it:

1. Quit Logic Pro X.

2. Click on your Desktop wallpaper to focus the Finder.

3. Click on Go in the menu bar, hold down the Option key on your keyboard, and choose Library from the Go menu.  This will take you to the User(!) Library folder

4. Once inside the User Library folder, go to the Caches folder and then the AudioUnitCache folder.

5. Drag this file to the trash: com.apple.audiounits.cache

6. Empty the trash.

7. Restart your computer.

8. Restart Logic X.

Does that help?

Best, Marnix

Hello xazqe,

On Macs, the Vienna Suite Audio Unit plug-ins are installed by default and cannot be deselected, this is why they are not specifically listed in the Installer.

Please check in /Library/Audio/Plug-Ins/Components/ - you should be able to find the Vienna Suite AU components there!

Generally, please make sure to allow all your music applications, especially Logic, to control SYNSOPOS when prompted. (SYNSOPOS is an essential part of eLicenser, our copy protection).

You can also adjust this setting later on in the Automation tab (System Preferences > Security & Privacy > Automation - please see screenshot)

If the Vienna Suite plug-ins are still not available in Logic, you may need to delete your AU cache file, which will force Logic to re-scan for plug-ins the next time you launch it:

1. Quit Logic Pro X.

2. Click on your Desktop wallpaper to focus the Finder.

3. Click on Go in the menu bar, hold down the Option key on your keyboard, and choose Library from the Go menu.  This will take you to the User(!) Library folder

4. Once inside the User Library folder, go to the Caches folder and then the AudioUnitCache folder.

5. Drag this file to the trash: com.apple.audiounits.cache

6. Empty the trash.

7. Restart your computer.

8. Restart Logic X.

Does that make a difference?

Hi Scott,

Thanks for the update - great to hear you were able to solve the problem!

Best, Marnix

Hi scottgius,

In Cubase, please make sure you have unchecked "Release Audio Driver when Application is in background" in "Devices" => "Device Setup" => "VST Audio System"

Does that solve the problem?

Hi tigerman,

The last released build of VE Pro 6, which could be installed on OSX 10.9, was 6.0.16068 - here is a direct link to it.

I remember vaguely that this version had issues in High Sierra though - if you experience problems on your 10.13 machine with it, please drop me a line at

Hi Lionberg,

Can it be that you have multiple WaveShells in your plug-in folders? If so, please remove all of them except the very newest one - does that make a difference?

Best, Marnix

Hi Ondine,

Please click on the double-arrow next to the virtual keyboard in Synchron Player to allow adjusting the keyboard range of the currently selected slot.

Hi All,

May I ask you to contact us directly at in this matter and please always include your system specifications, as well as screenshots of the error messages you are prompted with!

Hi JamesH,

This problem is currently under investigation - thanks for your patience!

Hi sottovoceprods,

I loaded your Nuendo project into Cubase, since I do not have Nuendo installed here at home.

No difference in Latency whatsoever, no matter wether I route the Kontakt signal into Bus 1, Bus 2 or Bus 3 in the VE Pro Server instance.

I also asked two of my colleagues with different systems to see if they could possibly reproduce your problem and they were unable to do so either.

Please review your Audio Connections routing (F4)in Nuendo, especially in the Control Room tab - this is a constant source of various latency oddities, for example when you are using listening busses or duplicate assignments...etc...

Also, please check wether "Constrain Latency Compensation" is enabled in Nuendo - this also might be causing the problems you are experiencing when not properly configured.

As for Threads per instance setting: unfortunately, there is no "one setting to rule them all", as this depends on so many factors. Please find more information about multiprocessing in VE Pro 7 at https://www.vsl.info/en/manuals/vep7/vep-server?q=multiprocessing#multiprocessing

Best, Marnix

Hallo martin240,

Der Vollständigkeit halber poste ich nach unserer Support-Email-Kommunikation von heute auch hier noch die Lösung des Problems:

Ein vollständiger erneuter Scan sollte an sich nur erfolgen, wenn der Cache-Ordner gelöscht wurde (möglicherweise durch eine Drittanbieter-Utility, die System-Caches säubert?) oder wenn ein manueller Rescan aus den Einstellungen ausgelöst wird.

Der Plugin-Cache-Ordner für VEP7 lautet:

/ Benutzer / IHR BENUTZERNAME / Bibliothek / Caches / VSL / Vienna Ensemble Pro / Cache

Kann es sein, dass Sie vielleicht mehrere WaveShell Dateien in Ihren Plug-in Ordnern liegen haben?
Wenn dem so ist, verschieben Sie bitte alle WaveShells ausser der allerneuesten aus den Plug-in Ordnern heraus.

==> Das Problem war tatsächlich eine ältere WaveShell.

Cheers, Marnix

Hi all,

The Reason Rack Plug-in only installs as VST3, whereas Vienna Ensemble Pro can only host VST2 plug-ins at this point.

The Reason Rack AU plug-in (on Macs obviously) is recognised by VE Pro, but only opens a blank window instead of its GUI and is therefore not operational in VE Pro 7 either.

I have already notified Reason Studio about this!

@gsrokmix: I could not find a message from you in this matter - I just found one support request from 2017 in our archives, which was in fact replied to within 24 hours.

Best, Marnix

Hi,

I must confirm that all our player plug-ins by default run in real time in DP to ensure proper operation and cannot be forced into Pre Gen mode.

Hi Matt,

Sure - all our software comes with Uninstallers, please find them in the respective application folders.
