This is an odd one... in R1 with R2 R3 and L1 on
if I play two note chord ( interval ) I do not hear the ghost note, When I add a third note, i hear the note.
It is a lower octave of one of the notes I am actually playing or maybe a unison.
I tried other registrations, some had this ghost phenomenon and others did not.
Of course I scrutined the eq, tuning, for abnormalities, and in the upper right hand corner there are about 6 buttons that I never pay attention to, I think the first 2 on the left side are always on.. related to touch.
I had hope maybe those buttons could be a cause, but not so.
I am also using my thumb drive as the holder of said registrations... so internal drives are removed from the puzzling situation.
Any ideas about the ghost notes?.. And btw, they are NOT "combination tones or Tartini tones".
