Hi John
The card is no longer available, having been replaced by the Echo DJ I/O. These cards are type2 slot cards that slip into a slot 1/4 x 2/1/2. You install the driver, designate the port in your program, and you're good to go. My SD2 module is a little better sounding, especially on drums and bass, but I have to carry around a MidiSport interface with the module. It is simply easier to keep my Indigo in the slot and go.
