i was wondering if it is possible to make automations on the different parameters of the H9 box in your DAW?
Well, the different parameters of the H9 are all controllable via MIDI. By default the first parameter is mapped to MIDI CC 22, the second to 23, and so on. So, you could control it that way.
and if it is somehow possible to use the effects of the H9 on sounds in the DAW and not only my synthesizers? or if you eventually had planned to make the stand-alone program into a VST one day?
Well, you could set up your host to send audio to the H9. We have talked about making an H9 Control VST plugin, but only to control the H9 and save your settings with your session. Since the H9 isn't a computer audio interface, there are limits on how easy it can be made to integrate with a DAW.
