It works !!
it was just that I had ultraschall.ShowLastErrorMessage() which still warn that there is no FX chain in the take initially (despite the fact it is not an error anymore), but as the rest of the script now works I can delete it.
Just a side note,
GetApiVersion returned date is 1 june 2019, and the third returned value is an empty string (I thought it should be date but here is how it works)
Code:
a = {}
a.versionnumber, a.version, a._, a.beta, a.tagline, a.date, a.build = ultraschall.GetApiVersion()
Maybe I just misread the API doc as it is not up to date.
Thanks for your work anyway !
I will tell n0ne that these functions are available for FastFX Finder
