Hi ! I have plugged in my Yamaha PSRE303 keyboard into the computer's USB jack using an EM-U 1X1 midi Tab, and I'm having the following time: When I hit the keyboard there is MIDI In information coming through, I know because it says which notes I am hitting, but when I've cued up a software instrument, record enabled and hit record, no midi information is springing up when I press notes. The track is not even being filled in with the green background/midi notes that would appear... Any help would be appreciated... I want some sound!!
