I recently repaired 2 korgs a M1 and a X5 who are working well after reparing them. I bougth another Korg M1 who had a broken knob due to exostaed switches. I replaced them but afterwards I noticed the A button of the cursor position keeps blinking. so I can’s switch between sounds by pushing the up and down button. I also replaced the battery holder and placed a new battery. I sysexed the original sound but won’t get the right sound or notification on the led witch sound is selected. all sounds are named INit … by selecting the sound by means of a number I get diferent sounds but can’t see what they are.
someone who knows wath can be the solution.
