Memory Protect; Midi Control & Midi Pgm Change - Yamaha SPX900 Operation Manual

MEMORY PROTECT

The MEMORY PROTECT function must be OFF prior to
performing a STORE operation. If you attempt to execute a
STORE while MEMORY PROTECT is ON. the
"PROTECTED" display will appear and the STORE operation
will be aborted.
1. Press the UTILITY key a few times until the MEMORY
PROTECT function appears.
2. MEMORY PROTECT can be turned ON by pressing the
parameter 0 key and off by pressing the parameter v key.
MIDI CONTROL & MIDI PGM CHANGE
The SPX900 makes it possible to select specific programs via
external MIDI control. You can set up the SPX900, for
example, so that when you select a voice on a synthesizer the
most appropriate effect for that voice is automatically
selected. This is accomplished because each time you select a
voice on your MIDI synthesizer it transmits the corresponding
MIDI PROGRAM CHANGE NUMBER. The SPX900
receives this PROGRAM CHANGE NUMBER and selects the
effect program that you have assigned to it using the MIDI
PROG CHANGE function which will be described below. The
SPX900 also accepts MIDI KEY ON EVENT messages to
trigger some of the gate effects, and MIDI KEY ON
NUMBERS to set the PITCH parameter of the PITCH
CHANGE effects. The SPX900 actually can be programmed
with four completely independent sets of MIDI PROGRAM
CHANGE NUMBER/MEMORY NUMBER assignments.
Each of these is contained in a different "bank": A. B, C or D.
Each BANK may also be programmed to receive on a
different MIDI channel. An example of the way the four banks
may be programmed with different receive channels and
program number/memory number assignments is given below:

Bank Selection and MIDI Channel Programming
1. Press the UTILITY key until the MIDI CONTROL
function appears.
2. The underline cursor should be under the BANK
parameter. Use the parameter a and v keys to select the
bank you wish to program.
3. Move the cursor to the "ch=" parameter by pressing the
PARAM key. then use the parameter 4 and v keys to set
the receive MIDI channel (1 + 16), the OMNI mode (all
channels can be received), or turn MIDI reception OFF for
the selected bank. The underline cursor can be moved back
to the BANK parameter if necessary by pressing the
SCROLL BACK key.
Assigning Effects to MIDI Program Change Numbers
1. Select the MIDI PGM CHANGE function using the
UTILITY key or program select
underline cursor should be under the PGM parameter.
2. Use the parameter and 0 keys to select the program
change number to which a new SPX900 memory location
number is to be assigned. The range of available program
change numbers is from 1 to 128.
3. Move the underline cursor to the MEM parameter by
pressing the PARAM key. Use the parameter a and v keys
to select the memory location number containing the effect
which is to be assigned to the currently selected program
change number.
4. Move the underline cursor back to the PGM parameter and
repeat the above steps to assign as many program change
numbers as necessary.
NOTE:
The program number/memory number assignments made
are stored in the BANK selected in the previous MIDI
CONTROL function. To program the program change/
memory number assignments for a different BANK, return
to the MIDI CONTROL function, select the desired BANK,
then program the required assignments.
