SELECTING AN EFFECT/MEMORY LOCATION

1. Effects and memory locations can only be selected when
the utility mode is not active (the UTILITY KEY indicator
is not lit). If the UTILITY key indicator is lit, press and
hold the UTILITY key until its indicator goes out and the
utility mode is exited.
2. Press the program select
decrement the memory location number shown on the LED
display. Hold either of these keys down for continuous
incrementing or decrementing. The name of the program
corresponding to the currently selected memory location
will be shown on the LCD, or "*** NO DATA ***" will
be displayed if a memory location between 41 and 99 is
selected into which an edited effect program has not been
stored. Note that at this stage the LED memory number
display is flashing, indicating that although a new location
has been selected, its contents have not yet been recalled.
3. When the desired memory location/effect has been
selected, press the RECALL key. The LED memory
number display will stop flashing and the selected effect
will be engaged.

BYPASSING THE EFFECT

There are two ways to switch the selected effect in and out: 1)
with the control panel BYPASS switch and 2) with a
footswitch connected to the connector-panel BYPASS
footswitch jack. An optional Yamaha FC5 Footswitch can be
used for foot-bypass control. In either case + when the
control-panel BYPASS key or BYPASS footswitch is pressed
+ the LED in the BYPASS key will light to indicate that the
selected program is currently being bypassed and the input
signal is directly routed to the output terminals (i.e. the effect
is OFF). Press the BYPASS key or footswitch a second time
to turn off the BYPASS Key LED and turn the effect back
ON.

ACCESSING & EDITING
THE PROGRAM PARAMETERS
Each SPX1000 program has 4 different groups of parameters
which are accessed by pressing the corresponding parameter
select keys:
KEY ACCESSES
PARAM The main effect parameters for each program.
These parameters will vary according the type
of program.
LEVEL The BALANCE and OUT LVL parameters for
each program.
EQ
The equalization or dynamic filter parameters
for each program.
INT. PARAM. Special "fine control" parameters for each
program. These parameters will vary
according to the type of program.
To call a specific group of parameters for the currently
selected effect program, press the appropriate parameter select
key. The next parameter within the group is called each time
the parameter select key for that group is pressed. In any
parameter group, the SCROLL BACK key can be used to
scroll backwards through the parameters. For example,
subsequent presses on the LEVEL parameter select key call
the following parameters:
BALANCE -> OUT LVL -> BALANCE -> etc.
The complete procedure for calling and editing parameters is:
1. Select and recall the program to be edited.
2. Press the parameter select key corresponding to the group
of parameters to be edited (PARAM, LEVEL, EQ or INT
PARAM) and the first of the selected group's parameters
will appear on the bottom line of the LCD.
3. Once the desired parameter has been called, its value can
be edited using the parameter

continuous incrementing or decrementing.
