MISO (Musical Instruments of the Seattle Opera) is a Microsoft Access database designed to track the Seattle Opera’s instrument collection. Before MISO, instruments were tracked using several spreadsheets that were inconsistent and difficult to update. The Seattle Opera realized it needed a better system when a cimbasso went missing. After a frantic search, it was discovered that the cimbasso was never missing - it had been in the Seattle Opera’s library all along. With MISO, all relevant instrument information, including location, current user and technical specifications are all combined into one location, ensuring that no instrument is lost.
