Just installed AF experience (2.5) on my imac (latest spec.) and when running within Garageband there are 2 issues, both concerning the Jupiter 8V. The presets are much quieter than those taken from the other synths, and the FX (chorus and delay) don't respond to tweaking. As I understand it the FX issue is common for AFE on all platforms (a confirmed bug) but the volume issue is not. (In logic the volumes are fine). However I understand that the volume issue used to affect the Jupiter in an early incarnation of AFE. Any thoughts most welcome and perhaps these issues could be addressed in a future update. As it stands the Jupiter presets are pretty much unusable in Garageband. Still a brilliant product though.
