My two cents: User Tracks, Realtracks or Soloist Tracks - all the same. Pre-recorded multibar fragments which are combined in sequence by the software to work well over different chords.

The artist being recorded is presented with a series of chords which they smoothly traverse on their instrument either with a steady rhythm or an improvisation. The software then takes all those chords and all those recordings and puts together a lookup table. Then when you present the software with a new chord sequence it can select segments of recordings which fit the bill. The more recordings the artist lays down the more options available when new chords are presented.

Simple as that. crazy

Oh, and welcome to the forum. grin
