Alright so I've been working in Garageband for about a month and have made a few tracks, but I've just come across a problem that I have yet to encounter, and I can't find anything about it online. When I was playing on the keyboard, I accidentally hit some keys, I'm not sure which ones, wherein lies the problem, but it made the whole keyboard turn to a faded grey and then I was unable to play on it anymore. I can still see it but I can do nothing. I opened and closed the program but the keyboard is still like that. It seems to me that I just need to hit something to fix it, but I have no idea what that is. There is nothing in product support about it or anything in forums. Any help would be appreciated.
Also. If the keyboard is not faded. It might just be that you have the velocity turned down to zero. turn it up :). the velocity controls are right below the keys when you have the keyboard on musical typing mode
