<< However, I think there are two problems. >>

<< First: Choose the guitar 2501, 3351, whether it matches the style perfectly, this test sounds more troublesome. >>
I chose these RealTracks for demonstration only and not due to their compatibility with the song. They are just different recordings of the same baritone guitar being played by the same artist, Brent Mason. That being the case does not mean they were sufficient choices stylistically for the song. In a Medley, any RealTrack the user thinks is appropriate can be selected and used.

<< Second: He can only play in the order of the insertion list, but cannot choose by himself. >>
No, that's not correct. I only detailed instructions for one use of the RealTrack Medley Maker and there are many other options to choose and create different variations of the playing order. As I also stated, the demonstration I outlined these steps is only a single method from several other ways to achieve variations of the playing order of the instrument. The MultiRiff option is another but Medleys can also be entered manually from the Bar Settings Page and custom settings placed at any bar determined by user input.

<< So, I think it is more appropriate to directly use the latest 2022 function multiriff instead of this function? >>
Yes. that's another way to accomplish the same thing.
