It's good enough especially considering the price. Is it a perfect duplicate of an acoustic Steinway Grand? No, but no electric keyboard really is. The action is great in my opinion, and I am a Pianist. I don't travel with mine but if you are traveling, I think this controller has a lot to offer in that it is bus powered as I mentioned, and you can add the optional music stand and or lap top stand. I went with the Studio over the Grand because I prefer something that is Bus Powered which eliminates many of the alternate keyboards mentioned in this thread. Other than this it is a very solid keyboard. I'm grateful Fatar did respond but I'm thinking they should post something about this issue, or recommend that people do a restore after they run the update. This will wipe out ANY settings you have started to customize and reverts the keyboard back to factory settings, keeping the firmware. You can do a full a restore from the keyboards control panel. One of their suggestions as a last resort was a full restore. The next day (with-in 24 hours) I did get a response that the update must have accidentally activated some of the extra features of the firmware. I contacted Fatar support via email, but right after I contacted them, I did a full restore (which wipes out all settings, but keeps the firmware etc.) This fixed everything.
