thanks uncle Dave,it works!but I got another problem.The clipping LED of the deltafex always stays red when I play the kb.I tried turning all those knobs(EFX,level,gain)as low as possible(hardly get any effects)but still seeing red.I see green only when I play a single note and release but becomes red when I play a continuous melody.Is continuous red normal or should it be blinking red???
