Description

We consider a mixed action approach where valence Wilson twisted mass
(Wtm) fermions at maximal twist are combined with CLS ensembles
consisting of $N_f$=2+1 flavours of O($a$)-improved Wilson sea quarks. We
present an update of the results of the matching of valence and sea
quarks, and of the subsequent continuum-limit scaling studies of
light-quark observables. A scale setting procedure combining the
O($a$)-improved Wilson and the Wtm regularisations will be discussed.
