We report on the determination of light quark masses with three sea-quark flavours based on a mixed action with maximally twisted valence fermions on CLS ensembles with O($a$)-improved Wilson sea quarks. The renormalisation and the renormalisation group running over a wide range of scales are based on existing non-perturbative computations in the Schrodinger functional scheme. The determinations of the light ($u$,$d$) and strange quark masses are based on a combination of the results from the unitary Wilson action with those from the mixed action.
