"- Zildjian SP1, SP2, and ZP1 are discontinued. They were discontinued at FXpansion even before ROLI purchased us. They were re-released as the BFD Zildjian Digital Vaults. Vol 1 library. If you get in touch with support, they should be able to issue you a serial number for the updated pack. You'll be able to download that, install it, and be good to go."
Which support? ROLI? Fxpansion? InMusic? BFDDrums.com?
Clear as mud.
