We have performed partial-wave analyses of the K{sup +}K{sup o}s {pi}{sup {minus}} system produced in the reactions K{sup {minus}}p {yields} K{sup +}K{sup o}s{pi}{sup {minus}}, {Lambda}/{Sigma}, {pi}{sup {minus}}p {yields} K{sup +}K{sup o}s {pi}{sup {minus}}n and {bar p}p {yields} K{sup +}K{sup o}s{pi}{sup {minus}} X at 8 GeV/c in substantially the same apparatus. We present and compare the results of the analysis of the three reactions in the mass range 1.24 GeV/c{sup 2} < M(KK{pi}) <1.56 GeV/c{sup 2}. In all three reactions the J{sup PG} = O{minus_plus}, 1{plus_minus} and 1{sup ++} waves are the most important. A strong f{sub 1}(1285) signal is evident in the {pi} and {bar p} beam data sets but not in the K data. There is evidence of {eta}(l280) production, especially in the n and 0 beam data. We find evidence of two O{sup {minus_plus}} states in the 1400 MeV/c{sup 2} mass region, but no compelling case for a 1{sup ++} resonance in this region. Finally, the 1{sup {plus_minus}} wave in the K beam data is consistent with an h` state below the K*K threshold.
