Nevermind.
I must have tried to load the samples before and pointed the plugin to the wrong project folder. After identifying and temporarily moving this folder I was able to relocate my samples.

Thanks anyway!

It's good to know were to find these files.

This Solved it.

Thanks a lot !!! @d-healey

I have been dealing with Hise for a few days now. I managed to build Hise-master with Visual Studio 2017 and create+export a first standalone application. When trying to export the whole thing as a vst plugin I got an error message and found out via the forum that the master version is outdated. So I switched to scriptnote and did exactly the same steps as needed to build Hise-master: Cloning the project, adding the third party SDKs and since I don't want to use IPP I disabled it in ProJucer in the module hi_core (both in plugin and standalone).
However, in Visual Studio I keep getting the error message: "...\hise-scriptnode\hi_streaming\hi_streaming.h(69): fatal error C1083: Unable to open file (include): "ipp.h": No such file or directory"
How can this be possible when I have excluded the use of IPP exactly as before? Have I perhaps overlooked something?
