I currently show FOUR different versions of SampleTank 4 in my Product Manager/Sounds window, including SampleTank 4 MAX. What's unclear is: do each of those versions have different instrument sets that would require all of them to be installed in order to have access to all patches? The 4 versions are 4, 4 CS (no option to install unfortunately), 4 MAX and 4 SE.
Any help would be appreciated.
