@Lindon

Hey Lindon, sorry, for the wrong format, and thanks for your tip! i´m new to this =) sat a lot of hours yesterday to figure this small piece of code out. :D

We build some kind of chord trigger, that get´s chord arrays from atm a json.

So you have around 8-10 chords in one set, that are mapped onto the keys. everything still pretty raw.

I defined a global var in the scriptprocessor, that holds the currently played "artificial" notes to get the current mapped notes into the interfacescript. Thats "chord".

The script is doing what i intended inside the HISE Environment but not after exporting.

That so far.

@ulrik Thanks. Putting the Message.sendToMidiOut inside both the functions did the trick. I think in the former version we had it in a sinegenerator chainelement. now i put it directly in a new project into the Mainelement Midiprocessor. Hope this makes sense.
Thanks for the info about ableton and reaper. Will be helpfull in the future! And generally thanks to both of you for helping out!
All the best
