One of the Hohner websites has videos on adjusting the reed offset (gap), tuning, and making repairs on chromatic harmonicas. Much of the information is applicable to melodica reed plates.

The video on adjusting the reed offset to fix problems or obtain the response that you want is very well done. See it here:
