I have an old electronic keyboard. When I play a triad, even using only my right hand, it sounds very distorted. Diads work passably well but triads cause this problem. Even worse if I play the root note with my left hand (root note an octave below the triad). Sounds extremely harsh and unmusical. Is this a characteristic of all electronic keyboards or it it likely due to my keyboard being very old? Would a reasonably priced (€250 give or take) new keyboard solve this problem? Thanks.
