M-Audio Midisport UNO is really the only interface that consistently works. I bought one when my Vetta 1 crashed. I reflashed using the Uno and Monkey, replaced the internal battery, the process worked pretty flawlessly except that the results were my Vetta 1 was upgraded to a Vetta 2 and the amp only works for about 30 minutes and locks back up, again. No replacement parts for vetta, no service for vetta. Thanks for nothing, Line 6. I hope you appreciated the thousands of dollars I spent with your company. I decided to spend it on a Marshall combo and a new pedal board. Line 6 is in my rear view mirror.
