Did you ever find out an answer? I have the same question.
I used Product Manager to install "SampleTank 4 Max". 95 zip files were downloaded and PMgr shows successful install.
In ST4, looking at just guitars, I can see the ones that are new with ST4 such as: Black LP & RedStrat, J200, and others.
However, missing are the guitars that the comparison doc lists as SampleTank 3 or SampleTank 2XL Instruments such as "Single Coil...", "Humbucker ...", "Clean LP1", etc.
Here is what I was expecting to see:
https://www.ikmultimedia.com/products/i ... arison.pdfSince we are on a 180 day countdown to get the sounds downloaded we really need a clear, unified process to get everything downloaded/installed. I do appreciate that PMgr apparently ran the installation for the 95 files saving me that time!
Note: PMgr also has an entry to download "SampleTank 4" (i.e., not "SampleTank 4 Max"). I started downloading that to see if the missing instruments may be there but the first few zip files look identical in size and content to files I'd already downloaded in the ST4Max install so I killed it rather than redundantly downloading/installing 80gb of files that already come with ST4Max. If the ST4 entry is a redundant subset of ST4Max, what is the purpose of the ST4 entry?
