<< Is this APF WAV file saved in the same folder of SGU, or saved somewhere else on C:, or just saved in the RAM?
How I can find this "conversion" WAV file in the computer? >>

Yes, it's saved and automatically named in the same folder as the SGU file. An SGU file must be saved before an APF can be saved. If the project hasn't been saved, there's a prompt to save.

<< I assume once you converted a RealTrack to APF, it's done, you can not revert back to RealTrack anymore. If you want change a few chords later, the APF doesn't regen, and you lost the original RealTrack. You need to find and insert the same RealTrack again, in order to regen, and re-convert to a new APF. >>

No. APF's can be undone and RealTracks restored. Rt. click on the track| Track Actions | Erase Performance Track
Sometimes you may have to erase the track data as well and select revert back to style instrument. This is done in the Track actions menu also.

<< Remaining in BiaB for production is always the goal. But probably it's not a good idea to convert any green tracks to orange, otherwise you lose the ability to regen should any changes happen on the way. A simple freeze may seem to be more practical. >>

Absolutely. The APF is a tool and use when it's the right tool for the job at hand.
