•Two synchronizations (PLO, TLO) are identified in vortex-induced vibrations.•PLO and TLO patterns are influenced by cubic stiffness and rotating velocity.•Strong nonlinearity alters synchronization and induces separation bubble breaks.•Rotating velocity suppresses quadrupole sound modes.•Nonlinear...
