Thisis hard to troubleshoot... The keyboard insynths are usually scanned as a matrix... If a disconnect diode has failed, then wrong notes can be triggered. There is USUALLY rows of the diodes on the circuit board where the keys hit. There are usually TWO contacts per key in order to sense key velocity. The lkey contacts are usually conductive rubber pills pressed against circuit traces under the keys. One sometimes needs to clean these contacts using 99% isoprophyl alcohol and Q tips.
I would do further testing of ALL combinations of notes played together to see if possibly any others show up as that could point to a particular failure.
