Primarily bug fixes, no new features added
Apple has updated it's live performance virtual-instrument and sound effects app MainStage to version 2.2.2, fixing some 14 issues mostly related to stability and compatibility along with general program issues. The update improves compatibility with the VAX-77 keyboard, and resolves a patch issue where patch lists weren't updated to VAX and Axiom keyboards if the keyboard lost and then regained connection after launching the program.
The other main issues tackled in the update relate to stability issues that could cause the program to quit unexpectedly on OS X 10.7.4, a serious bug that prevented the I/O plug-in from outputting audio, and a fix for a problem related to the download and installation of basic and additional content. Other issues fixed range from getting the correct URL for the release notes to several fixes for Screen Controls to ensure better and more reliable performance.
MainStage was once a part of the Logic Audio Suite, but late last year Apple spun out the program as a standalone app and moved it (along with Logic) to the Mac App Store. MainStage now sells for $30 on its own, with the v2.2.2 update available for free. There's been no word about the availability of the update for users who are still using earlier, non-MAS version of the Logic Suite, but the update may become available for those users through Software Update. Apple has encouraged MainStage 1.0 and 2.0 users to update to version 2.2 or later, which is exclusively available through the Mac App Store.
