> The drum beat is just the Rock 1 preset of the Suzuki Omnichord
I wonder if you need to pay royalties or get permission for that kind of thing... or is license to use it commercially included in the price of the instrument?
IANAL, but you don't need a license to publish yourself playing a piano or a guitar, and synthesizers are also musical instruments. That said, I'm not sure that's ever been tested in court, so if someone wanted to be a right-wing asshole about it, like take over Suzuki and try to get royalties from every hit song that used it, I guess it might be interesting.
