Power is flowing into the PSR-130 The sound is distorted and some- times cuts out. Battery power is low. Cause Solution This is normal and not the result of a defect Replace the batteries. Not all notes are heard when playing a number of notes simultaneously. There is a limit to the number of notes that can be played at a single time. The PSR-130 has a maximum polyphony limit of 12 note. That includes notes that are not only played on the keyboard but notes produced by Style, Song, and Auto Accompaniment functions. Therefore, if the total number of notes simultaneously produced exceeds the limit, some notes will be cut off or not sound at all. (page 11) The sound of the Voice changes from note to note. The AWM tone generation method uses multiple recordings (samples) of an instrument across the range of the keyboard; thus, the actual sound of the Voice may be slightly different from note to note. This is normal and not the result of a defect 18
