Sound Forge Studio 15 ----Version 15 -----Build 121---- 16 Bit
Will the Sound Doubler from Isotope work in Sound Forge Studio 15? If so, should you use the assigned folders for VST3 files or create a new folder in Programs 64. It's currently in the common files in the 64-bit section. I wasn't sure if you needed to create a VST and a VST3 folder or just use the current locations. A Plug-in location would seem more practical.
