Yamaha MM8 synth: Every 6th key dead

[Geir Holmavatn]

Hi,

Hac anyone experienced or repaired a Yamaha synth with this symptom? I
suspect it might be a loose keyboard connector or something.

Thanks for comments and suggestions.

regards Geir

Old Korg analog synth had similar problems located on one of 4 gate
boards but I seriously doubt any such architecture exists in something
this modern.

A common ground for that key grouping?
