SEIDS walks through Logic Pro's Session Player, an AI-driven feature that generates keyboard and bass parts that automatically follow your chord track.
For the keyboard player, she picks a broken chord style and shows how to shape it: complexity, hand range, spread, rhythm, fills, swing, and humanization controls like grace notes and dynamics.
Adding a bass player is just as quick. It locks into the existing chords automatically, and you can swap styles instantly, from modern R&B to a roots upright feel, without re-recording anything.
The takeaway is less about any single preset and more about the workflow: pick a player, choose a style, tweak the parameters until it feels right, and let it react to your progression.
