First thing is to check on which module the problem is. With the DVM measure at KLM-367/IC7/pin1 (obtain GND at KLM-367/TP3). Now turn the EG-intensity knob.

The oscillator for the arp is on the front panel board and feeds into the keyboard scan cpu. If the arp stops working check the 555 on the front panel board.
