Hello. Ive bought a brand new casio px-5s(we) model not long ago, and its great. But i have an issue: when i record phrase for egz. in bass. i press play phrase, and everything looks good, BUT when im editing song, and add the phrase i recorded before (in egz. bass), the phrase plays in piano only! no matter if i used drums/bass/ electric piano/ etc. while recording.. when song, it ALLWAYS plays in piano ONLY! i dont really know what to do (i red all the manual and tried all i could think off)... any ideas why? and how to fix it? help would be REALLY appreciated, thanks! p.s. that thing in sys rec setting is on (dont remember what its called :/)
