Audio from a plug-in using Aux Output Stems (AOS) is not delay compensated properly in Pro Tools 11.
1. Create one Instrument track and instantiate an AOS enabled VI plug-in such as Strike, Structure, UVI Workstation, etc.
2. Create two stereo Aux tracks and assign the inputs to different AOS outputs from the VI.
3. On the first Aux track, instantiate a plug-in that incurs a delay, such as the Pro Expander with the "Look Ahead" feature turned on.
Aux 2 is not delay compensated. As a result, the signals from aux 1 and aux 2 are out of alignment.
The Instrument track is not delay compensated either.
