Data Configuration and Handling Data Configuration and Handling The A3000 main memory loses all data at power off. It is therefore essential that you save all important data to disk before you switch off the power. Of course, you must also reload the data you wish to use each time you switch the power back on. This section describes the relationship between data in main memory and data stored on disk. Main Memory storage In addition to sample data and program data, the A3000 main memory also stores system parameters and sequence data. System Parameters Master tuning, total equalization, and other system-wide settings. These settings apply in common to all programs . Sequence Data Performance data received and recorded from an external MIDI device. (Sequence data exists in memory only if you load it from disk or generate it from an external device.) The following illustration shows the structure of all data in main memory.
