Sorry I don't know what you mean by "the parameters". As a general rule, we have the unit synced via MIDI, and used as an FX return from the mixer, or through S/PDIF connected directly to the audio interface. In terms of actual programs, it depends entirely on what you want. Personally, I love the large reverbs and the choruses, but it will do simple delays really well, and there are some whacky pitch shifting programs in there too.
