I am experiencing glitches with the PSR2100 recording. When I press the record function, I have gotten undesired styles called up. When I rechoose the correct style, and then choose intro B, I get intro C when I begin playing the style. I have to stop the sequence (keep recording) and then change intros and begin playing again. Later on, with my sequencer, I delete the undesired intro. What a hassle. I don't remember having this problem with the PSR2000.
