There are 2 version of EZkeys Instruments. “Regular” refers to the version you purchase when you first purchase an EZkeys Sound Library. In other words, if don’t have any other EZkeys Instruments registered to your account.
The other option when purchasing is “Sound Expansion”. If you already have a Regular EZkeys sound library registered to your Toontrack account you can then select the Sound Expansion purchase option when you purchase another. They are both identical products in every other aspect.
