With this release, all FireStudio-series interfaces, including discontinued models, are compatible with OS X Lion.
FireControl 2626 is for the FireStudio (26×26) and OS X Lion; FireStudio users who are running earlier versions of Mac OS X or who are using Microsoft Windows do not need and should not install this release. Users of all other FireStudio-series interfaces and users of StudioLive-series mixers should update to the recently released PreSonus Universal Control 1.5.2, which provides Lion compatibility and other enhancements for those products.
FireControl 2626 allows FireWire daisy-chaining of two FireStudio (26×26) interfaces, and it is possible to chain FireStudio interfaces with other FireStudio-series interfaces by running both FireControl 2626 and Universal Control 1.5.2 simultaneously.
