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.
