They see a keyboard as something they hook up to a computer sadly.
Not saying that it's something THAT bad.. I used my old Tyros as a midi controller because the keybed was fantastic. But on the other side of things i ALSO knew how to use the arranger side of the machine.

One thing bothers me about that video... Why was he using a piano sound while in the original tune you hear a very typical Roland Rock Organ? You can download free General Standard Soundfonts that have that exact sound on there.
