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.
