The UTILITY key provides access to four utility func-
tions. These functions are selected in the following se-
quence each time the UTILITY key is pressed:
MIDI PROGRAM CHANGE
The UTILITY key LED will light during selection of the
four utility functions, and will go out when the normal
mode is returned to. When the UTILITY LED is ON, the
PARAMETER and MEMORY NUMBER INCREMENT/
DECREMENT keys will perform special functions as
described below, so normal parameter and memory
selection can not be performed until the normal mode
This function makes it possible to provide new titles
for programs which you have edited and stored in user
memory (31 through 90). When the EDIT TITLE func-
tion is called, the lower line of the LCD will display the
"EDIT TITLE" function name, and the upper line will
display the title of the currently selected program.
The PARAMETER and BALANCE keys can then be us-
ed to move the cursor left and right, respectively, to
select the character to be changed. Place the cursor
over a character, then use the PARAMETER INCRE-
MENT/DECREMENT keys to scroll through the
character list, stopping at the desired character. Move
the cursor to the next character location and repeat this
operation until the new title is complete.
The available characters are as follows:
With the SPX90 it is possible to select specific pro-
grams via external MIDI control. For example, you can
set the SPX90 so that when you select a specific voice
on your MIDI synthesizer, the most appropriate effect
program for that voice is selected automatically. In this
case, the SPX90 is detecting the MIDI Program Change
signal. For the following programs only, the SPX90 also
detects the MIDI Note ON/OFF signal:
* GATE programs (GATE ON/OFF).
* PITCH programs (sets pitch).
* FREEZE programs (begin playback).
For MIDI program change operation, it is possible to pro-
gram four independent sets of program change/memory
number combinations. These are referred to as "banks"
in the SPX90. For example, you could program the four
banks with different combinations as shown in the
The second function accessed by the UTILITY key —
MIDI CNTRL — permits BANK selection and setting of
the MIDI channel number on which MIDI program
change data for that BANK will be received. The third
function accessed by the UTILITY key — MIDI PGM
CHANGE — makes it possible to set the SPX memory
number which will be called when a specific MIDI pro-
gram change number is received.
