UPDATE (3/24/23):
HISE now builds against the Faust version 2.54.0+ as default. If you want to keep on using the old Faust version 2.50.6 you will have to enable the projucer flag in the hi_faust_types modules HI_FAUST_NO_WARNING_MESSAGES, then save and recompile HISE. This should be the case on all platforms
