4: UTILITY FUNCTIONS
The SPX50D UTILITY button provides access to a number of
important functions. Each press on the UTILITY button ad-
vances to the next function until the UTILITY mode is exited:
TITLE EDIT ^ MIDI CONTROL = MIDI PRG
CHANGE = F.SW MEMORY RCL ^ exit UTILITY
mode. f |
TITLE EDIT
This function makes it possible to create original titles for pro-
grams you edit and store in memory locations 51 through 00.
The TITLE EDIT function is the first one to appear when the
UTILITY button is pressed. The "TITLE EDIT" function name
appears on the bottom line of the LCD, and an underline cursor
appears at the first character position on the top line. The
MEMORY and STORE buttons are used to move the cursor
back and forth, while the /\ and V buttons are used to select
a new character for the current cursor position. Simply move
the cursor to each character position in turn, selecting the ap-
propriate characters at each position.
The available characters are as follows:

MIDI BANK & CHANNEL ASSIGNMENT
The SPX50D makes it possible to select specific programs via
external MIDI control. You can set up the SPX50D, for example,
So that when you select a voice on your 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 PRO-
GRAM CHANGE NUMBER. The SPX50D receives this PRO-
GRAM CHANGE NUMBER and selects the effect program that
you have assigned to it using the MIDI PROG CHANGE func-
tion which will be described below. The SPX50D also accepts
MIDI KEY. ON EVENT messages to trigger some of the gate
effects, and MIDI KEY ON NUMBERS to set the PITCH pa-
rameter of the Pitch A effect. The SPX50D actually can be
programmed with four completely independent sets of MIDI
PROGRAM CHANGE NUMBER/MEMORY NUMBER assign-
ments. 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 pro-
gram number/memory number assignments is given below:
