During a demo, Henry Phipps, a Suno product manager, pointed to a song we had the model generate that included a flute-like synth with what sounded like a ping-pong delay effect on it: "I've never heard that before in previous models... what that says to me is that the model understands that this is an isolated sound that's being affected and needs to be reproduced faithfully in different parts of the stereo field."
