The spectrum of nucleon and $\\Delta$ resonances is extracted from simultaneous fits to several pion-induced reactions in addition to pion, eta and $K^+\\Lambda$ photoproduction off the proton. More than 40,000 data points up to a center-of-mass energy of E$\\sim$2.3 GeV including recently measured double-polarization observables are analyzed. The influence of the $\\gamma p\\to K^+\\Lambda$ channel on the extracted resonance parameters and the appearance of states not seen in other channels is investigated.
