Here some realtracks combinations that often, but not always, produce a melody likeness to other similar to songs those are posted. The numbers are the realtracks ID.

Bass Piano Drums Guitar Strings
533 528 Nash 128 372 976

532 527 Nash 128 969/976 Midi Slow strings.

Guess the drum choice could be any.

I have a table of other realtrack that work with other song types. "Bottom line it's the way realtracks are constructed that makes them produce a melody likeness when combined." I found some combination get closer than other to the melody likness. Of course "any" likeness to the melody make it easier for some folks to sing with a backing track created in the manner.

The 969/976 choice. The melody was 120 tempo and any time you put 976 BIAB defaults back to 969. 969 will work but I like the 976, even thought timing off, will work very well if you raise your song tempo to 140 and select 976 and then lower the arrangement back to 120. I like the 976 track. Since it's and electric guitar it can have a wide range of sounds. Even thought the 976 realtrack is set to 140 by BIAB it produces the sound I like at 120.

Maybe BIAB can give the user an option for the tempo or timing of a Jazz or Electric Guitar.

I have pulled this trick on other electric guitar tracks and bass and it give some interesting and exotic sounds which work well with some selections
