@Christoph-Hart Okay, I see. Too bad but I see the time-sucking black hole in re-inventing the wheel for you, especially for such a unique computing environment. Already lots of time spend making new features and fixing bugs. Not worth it.
@d-healey
I did use v2.1.0 that compiled by myself.
that source code from @Lindon reply.
I tried compile "BasicSynth" (from hise_tutorial ) Xcode don't said same errors.
But Xcode says another issues:

I think this is just not declared in this source code.
Anyway, I'll study more.
