@Lindon thank you very much! this worked for me.

I did not know that i had to follow this practice, on the internet i couldn't find this solution.

But again thank you and i hope some other people will see this

Hi! i am new to hise and it's really useful to create vsts.

I just wanted to create a pitched up delay, but i noticed there are no pitch shifting nodes.
so i compiled a version with faust and i managed to get a pretty nice (for me) result.

The problem is that if i export the vst, with the faust node, the plugin loads but it outputs an untouched signal.
If i export only the delay part with no faust, the delay works fine.
I tried also with a test script that did basically nothing:
import("stdfaust.lib"); process = _, _;
but as soon as i add faust and export it, the plugin stops working.
I am using the latest version of both hise and faust, i also modified the appconfig.h to include faust and recompiled hise multiple times.

everything works well in hise (i test it adding a waveform generator)
I think i am missing some export settings to include faust.

I don't think it's a routing problem because when i export with a faust node, the delay does not work (even the dry/wet knob)

I don't know what to do, if someone could help me, i would really appreciate it.
