Amplitube CS for iPad, GarageBand, and Audio Unit?

[craigik]

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.

The CS version is free with a limited amount of gear. The non-CS version has more gear and is a paid app.

At this time AmpliTube does support Audiobus and Inter-App audio but is not an Audio Units plugin on iOS. It is an AU, VST, and AAX plugin on Mac/PC, though.
