I have read your Artist Performance Tracks post written in 2020. The post was more of a feature introductory than a step by step tutorial.
Could you give a bit more details on how you and your brothers use the APT/APF in real life productions?
Artist Performance Files are custom audio User Tracks attached to any BIAB project...
My understanding is APF is just a WAV/WMA file being mapped by the chord structure inside a SGU template with the same file name. This WAV file, can be a single instrument, or multi instruments, or a song, or external recordings. If a chord is later used but not pre-made in the SGU template, BiaB will use its zPlane Elastique engine to pitch shift to the nearest chord.
As I've searched, there's no video tutorial on YouTube specifically talks about using APT/APF. So How do I open a factory made APT/APF in BiaB? What exactly are the functional differences between an APT/APF and a regular RealTrack?
