Now supports use with the Yamaha Expansion Manager (V2.5.3 or later). The function "Part On/Off" (for the Left, Right 1, Right 2, Right 3 or Mic part) is newly assignable to the foot pedals. Fixed a problem in which the detail settings of the "Part On/Off" function for each one of the ASSIGNABLE buttons would not be loaded properly from the Registration Memory or System Backup. Fixed other problems.
