If you're gonna be playing it live then you might wanna get a stage piano; way easier to carry around. Ultimately it doesn't really matter what kind of digital piano you get, as long as it has weighted keys and you like the sound. This is what I play live, and I've had only good experiences:…

It sounds like it's trying to go to a resolution not supported by your monitor. Try adding the width and height of your resolution to the launch options (for example, mine are -height 1280 -width 1024)
Combining antipsychotics with psychedelics has been described as a mental straight-jacket. It's a really bad idea. Benzos are a good option though, along with opiates.
I was under the impression that one of them gave more of a physical high, while the other was more mental. Is there any simple way of telling them apart from looking at them?
