[maybel]

Hi ! im new here. Hi to music and piano lovers ! i have now kawai es 120 . i used to have kawai es110 gave it to my nieces. could someone please help me how to replay 1st, 2nd and 3rd song after recording? I always seem to replay just the latest recording i made. should i first press recording then A0 or B0 or C1? or press both at the same time or the key first then play??? I used to do it before but don't know why it won't work now. thanks
