I tried setting up 1 sound on R1 and one on R2 (PSR550) and found that R2 (right hand tone) and also L (left hand tone) do not have effects. If I setup an organ sound in L and R1, when I turn on the DSP (rotating speakers), only R1 has the effect. Am I doing something wrong? Is their a work around solution for this unwanted feature?
