I press the keys and move them to test the aftertouch and it doesn't do anything. I tested it with virtual synths and on midi-ox, the latter showing no messages.
I used the alesis VI editor to map aftertouch messages to a knob, and it is recognized by midi-ox, outputting "channel aft".
There are no youtube videos of the VI series showing an example of the aftertouch use. So I don't know if mine is faulty or am I missing something to do.
