Onstage and in the studio, DeMarcus relies on Yamaha keyboards, especially the Motif ES8. "I have a grand piano shell with a Motif inside that I play live," he says. "I have another one here in my studio, and I also have the Motif Rack. It's my favorite synth--it's been the meat and potatoes of everything I've worked on and everything I've produced. It has exactly what I'm looking for: I can dial up sounds so quickly, and it has all the textures I need, the pads and the other synth sounds. For just about every application I've ever needed, the Motif has fit the bill. I also have a Yamaha C7 grand piano in my studio, and the Motif feels more like it than any 88-key weighted keyboard I've ever used."
