Pion- and photo-induced transition amplitudes to $\Lambda K$, $\Sigma   K$, and $N\eta$
  Pion and photo-induced inelastic reactions off protons are studied in a multichannel partial-wave analysis. Properties of nucleon and $\Delta$ resonances are derived and compared to previous analyses. Amplitudes are shown for transitions to $N\eta$, $\Lambda K$, and $\Sigma K$ final states.
