First question, what is the difference between the "CS" version and the non-CS version in the app store other than you have to pay up front for the non-CS version?
I am new to MAC/iOS, but it seems the "Audio Unit Extensions" is the iOS equivalent of VST in Windows. I can get Inter-App Audio recording working with Amplitube but it is like recording without a VST. That is, it records the "processed" audio and cannot change to different sound later. Are there Audio Unit Extensions for Amplitube in iOS? Thanks.
