Yeah, the Delfina card is now upgraded a bit by the new producers and is now called Flipper. I reckon it's the model you're thinking about when you say Delfina, and I guess you've allready been to
this site to read about it?
I don't know if any sound-progs really take advantage of the fact that it has a DSP in it, which is a shame if they don't. My knowledge on it is like none, so I might be mistaken, but I haven't heard about any DSP revolution on the miggy. There's a guy who made an initiative before we wrote the year 2000, but it became with
the initiative.
