I've had my Yamaha DGX-203 for a year and a half and have never had a problem with it. However, when I try to record using an accompaniment, I get (1) a drum pattern/intro that I did NOT ask for; and (2) do NOT get what I DID program in. This drum intro was originally recorded on song number 31; I have cleared it, but it hasn't gone away. When I try to record on another channel (e.g. song number 33), it defaults back to song number 31 and gives me the drum intro. Sounds like something's stuck, but I have no idea how to clear it up. Any insight? Has this happened to you?
