DX21 CASSETTE LOAD

NOTE:
If you have a voice set programmed on a Yamaha DX21 Digital Programmable
Algorithm Synthesizer, these voices can be transferred from data cassette into
the DX100. Of course, since the DX100 has 24 voice memories while the
DX21 has 32, using the DX100 cassette LOAD operation will load only the
first 24 voices of the DX21 32-voice set into the INTERNAL memory. The
other voices (25—32) can be loaded using the DX100 LOAD SINGLE function.
The voice numbers for voices 25 through 32 are accessed by pressing the
STORE, FUNCTION, EDIT, INTERNAL PLAY, and BANK A—D buttons.

12: MEMORY PROTECT

This function turns the DX100 MEMORY PROTECT function on or off. When on,
the internal RAM voice memory cannot be altered using the STORE or CASSETTE
LOAD functions. The MEMORY PROTECT function does not affect the voice edit
buffer, so the INIT VOICE, RECALL EDIT, and CASSETTE LOAD SINGLE functions
will operate whether MEMORY protect is on or off.
When this function is called, the LCD will read either "M. Protect:on" or "M.
Protect:off", according to the current state of the MEMORY PROTECT function
(MEMORY PROTECT is automatically turned ON each time mains power to the
DX100 is turned ON). The -1/+1 buttons and DATA ENTRY control are used to
turn MEMORY PROTECT on or off.
This group of functions deals with parameters which control the transmission and
reception of MIDI data via the DX100's MIDI OUT and MIDI IN terminals. This
section will describe how each parameter is programmed, while actual operational
details will depend entirely on the type of MIDI equipment with which the DX100
will be used.
2: MIDI ON-OFF
This function turns transmission and reception via the DX100's MIDI terminals
on or off. When on, the DX100 can transmit or receive MIDI data to or from external
MIDI equipment. When off, no MIDI data interchange is possible.
This function is turned on or off using the -1/+1 buttons or DATA ENTRY slider.
3: CHANNEL
The DX100 is capable of receiving or transmitting data on any of the 16 available
MIDI channels, or receiving in the OMNI mode which enables reception on all
channels simultaneously. This function is used to set the desired MIDI receive or
transmit channel or activate the OMNI receive mode. The receive or transmit channel
