44.1 kHz and 48 kHz vstis

How is it possible to manage vstis with different sample rates ?
I have the case with VSL (44.1) and Hautpwerk (48). The organ in Hauptwerk is awfully detuned (and it’s not possible to change the sample rate in Hauptwerk).

You need to set all of your audio devices and plug-ins to have the same sample rate. This isn’t a Dorico problem as such, so perhaps you need to contact the manufacturers of VSL and Hauptwerk to find out from them how to adjust the sample rates in their instruments?
