I plugged the USB into my USB port and Vista installed the driver automatically.
So I did not download and install a specific Vista driver.
Now, UC-16 is recognized by both Reaktor 5 and Live 6. It works in Reaktor with midi learn but it does not work in Live 6. Live's midi indicator lights up when I tweak a knob but when I go into the midi mapping mode nothing is happening when I midi learn.
Driver issue?
