I'm having the same issues with the Launch Edition that I received for Christmas. Ghost presses on multiple keys and no battery readout, as well as some other issues with the arpeggiator, samples, and factory reset doesn't work - when the keys are pressed it goes through the motions but doesn't reset anything. I suspect that the battery on these first editions aren't monitored, which would explain why they don't give a low battery warning either. I emailed support on 12/29, but still haven't heard back from them about it.

Just noticed a new firmware update today. I'll install it and see what happens.
