MusicTechHelpGuy builds a keyboard part with Logic Pro's Session Keyboard Player, then splits the region to give an arrangement two distinct personalities instead of one static loop.
He extends the chord progression with a final C add9 voicing to match what the guitar is actually playing, keeping the harmony consistent across instruments.
Using command-T to split the region at bar six, he cranks intensity and complexity for an energetic intro, then dials both back for a simpler pattern once vocals enter.
Hand-spacing sliders control voicing width, letting you isolate or remove the left or right hand entirely for a thinner texture.
