The change of articulations with MIDI-notes works only with single instruments - when using sections: the slot is visually changed but not the corresponding samples…
New message: I confronted the soundiron support with that problem and received the following answer which I quote here:
"Hi there,
Thanks for reaching out and sorry you’re having trouble.
We just discovered this bug this past weekend - I have let the halion developer know so he should have it fixed and updated soon.
Nathan" - so we stay hopefully … Hi to all!
