It is obvious that Rig Manager has more and more problems. Copy / paste that do not work, rename rigs not registered, store performance in local library that doesn't work, etc..
It becomes very unsecure to work with this software (V3.5.27). Yes, I can contact the support but too complicated to describe, ask a video etc...
Could a reinstall complete of the OS solve all theses problems ?
NB : I use the Kemper since 5 years.
