We are happy to announce that all Spectrasonics products are Mac OSX Tiger approved!
Audio Units updates for Atmosphere/Trilogy/Classic Stylus are available that fix Tiger, AU Validation, Sample Rate/Tuning and all known DP 4.52 and higher issues including muting problem and lost presets when bouncing.
Atmosphere/Trilogy/Classic Stylus VST and RTAS versions do not need updating for Tiger compatibility, they should work fine with the current versions.
All current versions of Stylus RMX are Tiger compatible and do not need updating at this time.
All the best,
The Spectrasonics team
