There are no upgrade paths from VIor SYNCHRON-ized to Synchron.

VI = Libraries recorded at Silent Stage Vienna

SYNCHRON-ized = VI Libraries ported over to Synchron Player and made sound-compatible with Synchron Libraries out of the box

Synchron = Recorded at Synchron Stage Vienna

You can upgrade your Special Editions to SYNCHRON-ized Special Edition (and I can only highly recommend doing that for all the additional content you will get, as well as a Concert D Light piano). From there it is possible to upgrade to the SYNCHRON-ized libraries.

Or you upgrade to the VI libraries and from there to the SYNCHRON-ized ones, which would be a great path as well due to the 50% VI discount right now.

Thanks for your reply! A couple of questions:

1) Is the difference between Synchron-ized and Synchron the stage the samples were recorded?
2) Are Synchron-ized samples my special edition samples (the same samples), but just with Synchron player compatibility? Or were the samples recorded from scratch?
3) Can I use Vienna Instruments Pro with Synchron-ized or Synchron samples or is this tool obsolete after upgrading from VI because of the new Synchron player?

1. Yes, completely new recordings in a multi-mic setup
2. Yes, they are the same samples with some editing and out-of-the-box presets, so you don't have to care about reverb if you don't want to. The SYNCHRON-ized Special Editions also got additional instruments and articulations, so I highly recommend the upgrade. If you don't like the included reverb there is a mixer preset included that will disable it, so you get the original sound.
3. SYNCHRON-ized libraries can only be used with the Synchron Player. You will still keep the VI licenses and can use the VI Player as well if you like. This is also important to not break old/archived projects.

Thank you!

Vibrato control is not included in Special Editions.

While the large VI and SYNCHRON-ized libraries have those, if you like the sound of Synchron Strings Pro go for it instead. I would still recommend upgrading the Special Editions to the SYNCHRON-ized Special Editions, this way you will have them pre-mixed out-of-the-box in a Synchron compatible way, and you can directly use them together with Synchron Strings Pro.

Thank you!

What is the cheapest way to get that Vibrator control? Which large VI or synchronized libraries have such strings?

All VI Strings Strings (Solo, Chamber, Orchestral, a bit limited Appassionata).

All SYNCHRON-ized Strings (Solo, Chamber Orchestral, Appassionata).

All Synchron Strings (Strings Pro, Solo Strings, Duality Strings, and with some limitations the Strings in Big Bang Orchestra).

In short: Only Special Editions and Prime Edition do not come with multiple vibrato variations.

Thanks!

I bought the synchron-ized special editions 1, 1+, 2 and 2+. The Vienna Assistent lets me download them and also the synchron player, but does not know I already have the old VI Special Editions on my SSD.

Do I need to downlad and install the entire about 120 GB? Is it a completely new installation? Should I delete the old library after installing the synchron-ized version (unless I want to play the old samples in Vienna Instruments Pro)?

Because having both special edition and synchron-ized special edition on my SSD would need 190 GB...and I don't have much space left on my SSD.

It does not let me add my VI special editions. "No VSL data found". I have to download the entire special editions again although it is already on my SSD and then the synchron-ized special editions.

It even lists the correct folder when I click on the special edition, but still no library appears in the "installed" section. When I click on "add existing library" and select the folder that contains all the special edition folders, I get an error.

Now an ilok folder appeared...I added it and vol. 1 was added to my installed products...however, vol. 2 is still missing.

I think it is best to delete the entire VSL folder and download the whole 190 GB again.

Yes, these are completely new data, you need to re-download them.

I guess you are still using the eLicenser version of the VI Special Editions? These are not compatible with the latest players and Vienna Assistant. You should delete the old content and if you need project compatibility download the iLok variant from teh Assistant instead.

Just for clarification: eLicenser and iLo kdata are incompatible, every library has to be re-downloaded for iLok. If you have isntallation data from pre-iLok times they will not work. If they are already iLok isntallation from these will still take some time and a progress bar will appear validating the data and installing them after that.

Thanks. I bought the special editions in 2017 and 2018 and moved all licenses to the online account, but some remained on the hardware ilok.

It's not important where the license is stored, as long as the USB key is connected / the Cloud is opened on your system.

I finished installing special edition VI, synchron player, vienna instruments pro etc. ...
Downloading synchron-ized special edition now.

Installing synchron player, vienna instruments pro and synchron piano did not display any window where I want to install it nor were there shortcuts created.

I created them myself (desktop shortcuts). Is this supposed to be like that?
