New preliminary results from COMPASS on pion and kaon multiplicities in Semi-Inclusive Deep Inelastic Scattering on a proton target are presented. These proton findings serve as a complementary dataset to the deuteron results published in 2017. In this updated analysis, we have implemented an enhanced treatment of Radiative Corrections using DJANGOH MC. A comparison with the previously employed method reveals relative differences of up to 12% in terms of multiplicities. Despite these modifications, the preliminary COMPASS kaon results continue to exhibit incompatibility with those from HERMES. The presented results will provide an important input for global fragmentation function fits.
