<< 4. Open the demo sgu "_BALBMS2 demo (ALL REALTRACKS-Ballads,BrentElGuitSol,ElBass,ElGuits,B3Organ)", and this is the chord sheet for the demo audio. I can confirm this, as I already verified the chords with a chord detection software on the demo audio. >>

Correct. This is solid evidence the 'performance' of the demo audio came from a RealTrack data file and not necessarily a Performance Set track.

This also appears to be evidence that data clips solos as long as 1:15 minutes exist in RealTrack instruments data files in their data folder.

<< 5. You can open the demo sgu, sit there for an hour, try to generate the same solo, and you won't get it. Even though you have the chord sheet exactly the same as the demo audio, you can't recreate the demo audio. The algorithm is not invented yet. >>

Absolutely correct. This is the heart of the subject. If you don't get anything else from this discussion, understand point #5.

One can open a demo, any demo, or any SGU file, sit for an hour generating the chart over and again and not get that same solo. There are several causes for this, some intentional and some by design.

For instance:

By design, RealTracks data files residing in every RealTracks data folder are not Performances of songs. They are recordings playing propriatary charts designed and intended for propriatary performances created by implementing the BIAB algorithm, tools, features, and processes in conjunction with user input information to create a unique, distinct and solitary audio performance.

By user choice, one is sitting for an hour or more regenerating a chart they have provided their input and settings but choosing not to implement any of the advanced tools, features, techniques and processes of the BIAB algorithm. This futile effort outputs exactly what one should expect - a mediocre performance. You are relying solely on the Chord Sheet that's exactly the same as the demo audio but every other element of that production is left out. It's not due to the algorithm not being invented yet, the algorithm is there but hasn't been implemented. You have not indicated anywhere that you are doing anything other than entering the same chords as the demo, in the same key and tempo and generating over and over.

<< 6. Demo songs were not generated by BiaB. BiaB doesn't have an algorithm to keep 16 bars of original recording track unchanged. The only way to extract 16 bars of audio from the performance track unchanged, is to manually cut it out, aka "straight out of the box". >>

Nonsense. Your own photos show a 16 bar of original recording unchanged in RT#1167 data file eg4800.wma.

There has been no evidence presented other than what PG Music puts in every demo video presentation for many years that what is being played is generated by BIAB.

I'm not sure how you're arriving at the #6 statement when evidence you posted clearly shows that 16 bar or original recording track unchanged. What evidence can be shown that contradicts the PG Music Web site and the written statement in every demo video for years to the contrary of your statement?
