Strange speaker siren sound...?
hello.- a month ago i had a problem with my midi system (with strange hard disk behavior). I solved that it was a ground problem. I replug my main socket and everything worked ok. During that situation the system after some time of work started to produce a LoUD sirene sound from the speakers. Because it was late at night i disconected the speaker and since then i have it that way.. Anyone knows what it was?
