  We present the results of a coupled-channel model for $\bar{K}N$ scattering
in the resonance region. The model fulfills unitarity, has the correct
analytical properties for the amplitudes and the partial waves have the right
threshold behavior. The parameters of the model have been established by
fitting single-energy partial waves up to $J=7/2$ and up to 2.15 GeV of
center-of-mass energy. The $\Lambda^*$ and $\Sigma^*$ spectra has been
obtained, providing a comprehensive picture of the $S=-1$ hyperon spectrum. We
use the structure of the hyperon spectrum and Regge phenomenology to gain
insight on the nature of the $\Lambda(1405)$ resonances.
