We're in the process of performing updates to all BFD Expansion & BFD Groove Pack installers, the BFD3 installer itself and the BFD3 Core Library installers, as the installer systems require an update to allow the installation to succeed on macOS Catalina 10.15. Older Geist2 Expanders also require this update, and the Geist2 installer requires a smaller patch to avoid any warnings during installation that Catalina has introduced. Given the size of this task that is underway, we're unable to give a specific date as to when these updates will be complete, but we aim to make these available as soon as possible.
Testing has also been performed on the latest 10.15.2 beta version of Catalina, and we can confirm that the latest versions of Strobe2 and Cypher2 should install without issue. The Geist2 installation can proceed successfully with a workaround that our support team can provide; if you encounter any installation issues with Strobe2, Cypher2 or Geist2, please let our support team know - https://support.roli.com/request
Other than BFD3 folder permissions issues raised earlier in this thread, we're not currently aware of any other compatibility issues for any FXpansion software that exists on a system when updating to Catalina from a previous macOS version. Should you encounter any such issues, please let our support team know.
Thank your for your continued patience while we work to update all affected installers and products.
