Got the Snazzy FX Ardcore incl. Expander offered second hand like new for 50% of the new price, could not resist and bought it. Took only an hour or two till the first program was uploaded and working.
Although there was the usual hiccup with the drivers on macOS it worked ! Even without disabling the Apple drivers.
Have to test now on new macOS Sierra … Thanks winter is coming and long dark days/nights for deep sound explorations.
