Re: MG-1 won't play B, C and C#

replaced the 4558 and de-soldered and re-soldered all the new MM5823 and still no High A, the middle and low A are warble/fuzz notes in Polyphony, and in Mono mode i get that notes only play when others are held down.

time to try the U8 741 and time to buy a multimeter :)
