Sounds like you are overloading the capabilities. Basically, you have too many notes sounding at once. It doesn't have a massive amount of polyphony.

If you open up the case and look at the rear of the keys, I expect you will see that there is a small spring connected to the rear of each key. i suspect the unit was dropped in transit and some of these springs have popped off. If so, just reattach them using a pair of needle nose pliers. If however it was dropped hard enough to break the fingers that the springs attach to you'll have to replace those keys. This may be a repair shop job. it may also not be cost effective to do the job. Good Luck!

You can't add songs to the LK-30 song bank. I suspect you would need to take apart the keyboard and replace the ROM (read-only memory) chip to get a different song collection. Most Casio electronic instrument manuals are available from http://support.casio.com/en/manual/manual.php?cid=008 . However, I found the LK-30 manual at manualslib.com: https://www.manualslib.com/manual/358460/Casio-Lk-30.html . I wish that I had better news for you. Cindy Wells
