i bought it after demoing it for a few weeks and today for me was very interesting. i started reading the manual. 
even with having good results on the fly this is a must do.
halion 5 isnt overkill at all for me. after quickreading the manual this is something that is technically years beyond everything else i have seen (once you get the picture).
but it seems that there are very few people who see the power of this vsti as f.e. the presets compared to the engine are really from the stoneage and no one else seems to use it as far as i could notice. So the tech guys give you the means, but the show-off guys are not using it.
that is why this tread is a must have for a future release. preset sharing…
in fact the combination of the flexphraser, the midiplayer and the drumthing combined with the perfect integration and exchange possibilities back and forward from one to the other in cubase are far better then anything f.e. specrasonics, native instruments and the rest of the competition have been showing as we speak (but for most speaking about creating interesting automated midi data)
this is completely limitless if your goal is automated orchestration.
and the factory content is a bit outdated. So extra soundpacks are welcome here, but then again they are protected. That is a bit a drawback. Everything should be done from groundlevel.
i will be posting a vst sound file within a couple of weeks.
tip: if someone is looking on the exchange front of how to: look in the manual for “vst sound file”.
(not the presets)
kind regards,
