BandLab calls Studio Instruments Suite an add-on.
Open Bandlab Assistant
Select "Apps" tab
Select the down arrow next to the Cakewalk by BandLab "Open" button
Pop-up sub menu displays
Select "Install Add-ons ..."
Pop-up sub menu displays
Check "Studio Instruments Suite"
Select Install button.

Note: The Melodyne selection is a time limited free trial. If you install it there is no way to uninstall it. You can get the same thing from the Celemony website.

I have not installed Drum Replacer or Theme Editor. Theme Editor allows you to modify the Cakewalk by BandLab interface colors. Drum Replacer tries to identify drum hits and lets you replace existing sounds with other sounds of your choice. I haven't played with either.
