I run Analog Factory 2.0 on Ableton Live 7.0.3 in Mac OS X 10.4.11.
The software sounds fantastic, but there are lots of bugs:
(1) Often when I insert an instance of AF the AF interface does not appear in the pop up window, just a white screen so I cannot browse sounds. If I restart the software and the machine the white screen is still there for that instance of AF. It happens around 50% of the time I would say.
(2) I spend time modifying a sound, save the project and when I go back in it has completely changed, this happens intermittently too.
(3) The pots on the controller always revert each setting to zero so I can't make smooth changes to presets in a live situation.
Also CPU usage is very high, I can only run 4 instances at the same time!
It's a shame as I have a powerful Mac Book Pro and I didn't expect so many problems with AF.
Maybe somebody from Arturia will notify us of when an update release will be available which will repair some of these issues?
