there are karaoke midi files available on a pay basis. here's just one
https://www.midi.com.au/genres/midi-karaoke/

for 'clones' of particualr tracks, these will open fine in RealBand with any distinctive riffs or instrumental breaks reproducd as close as midi can get them.

BIAB is not the program for 'cloning' commercial tracks. you could put in the chords for satisfaction by the rolling stones and you'd still have to record the guitar riff and the bass part wouldn't be what Bill Wyman played either.

with a karaoke track opened in RealBand you'll get as close to the recording as posible.
