A13: CASSETTE SAVE/VERIFY
This function actually incorporates two “sub-functions” —SAVE and VERIFY. After calling this function, subsequent presses on the B13 button alternate between the SAVE and VERIFY sub- functions. Normally, however, you will start with the SAVE function which saves the entire contents of the DX21 RAM voice memory onto cassette tape. The VERIFY function is then used to check the saved data against the data still in RAM memory, to ensure that no errors occured in the SAVE process. Before using this function, make sure that an appropriate data cassette recorder is properly connected to the DX21 as described in CHAPTER I: SETTING UP. When this function is initially called the LCD will read “Save to Tape ?”. Confirm your intention to save the contents of the 32 voice memory locations to cassette tape by pressing the DATA ENTRY YES button. The display will then read “from Mem to Tape, all ready ?“. At this point reconfirm that the cassette recorder is set up properly, make sure a suitable blank tape is loaded into the cassette recorder, and start the recorder running in the RECORD mode. To begin the actual save operation press the DATA ENTRY YES button. Pressing another function button, a PLAY mode button or the EDIT mode button prior to the final step in the above process will abort the CASSETTE SAVE function. As the DX21 saves each voice to tape, the upper line of the display will indicate the voice number being saved. When all 32 voices have been saved the DX21 will automatically go into the tape verify mode, permitting you to check that the data was recorded properly.
Stop the cassette recorder. The LCD will now read “Verify Tape ?“. To verify, first rewind the tape to the beginning of the file just saved, then press the DATA ENTRY YES button in response to the “Verify Tape ?” display which should be showing. the display will now read “Verify Tape, ready?“. Press the DATA ENTRY YES button then start the cassette recorder running in the PLAY mode. The DX21 will now read each voice from the cassette tape, and compare it with the corresponding voice data in the RAM voice memory. If the cassette and RAM data matches, the display will read “VERIFY COMPLETED”. Any PLAY mode can then be entered simply by pressing the corresponding mode selector button.
If an error is encountered this fact will be displayed on the LCD. If this happens, go back and try the SAVE process—followed by the VERIFY process—one more time. If the error persists then you may have to carefully adjust the record and/or playback level of the cassette recorder, or use a higher quality recorder or tape. Be sure to check that all cassette connections are made properly.
