Guitar Hero, let me introduce you to a Casio Keyboard. Casio, this is Guitar Hero.
9 months later, this bastard child of GH+Casio is born and people will claim it to be cutting edge. Bullshit. Avant garde? Hell no. Shit? Yes, in a single word, YES!
Geddy Lee and some other bass players latched on to the midi bass for a while back in the 80's. There's a reason they didn't continue with it. Cutting edge? At the time, perhaps. Did it sound better than what they were using? Nope.
If it ain't broke, don't "fix" it.
