Here's EZBass
same deal as EZKeys create a Midi Chord track, highlight the chords on the chord sheet where EZBass will take over, drag the Chords track to DROP MID then drag that into EZBass to the same bar number +2, click on the chord and select bass riff to replace with.
This is not using PlayableRealTracks in Piano Roll as the were no charts with the 514 Funk Slap Bass so I found a Modern Slap Funk Bass SFZ in the PlayableRealTracks and just used the volume automation to mute the original RT.
