BASIC OPERATIONS

Before actually selecting or editing programs on your SPX90, make sure that all connections have been made pro-
perly, and that the INPUT LEVEL switch, OUTPUT LEVEL switch, and INPUT LEVEL control have been properly
set according to the source signal and equipment to which the SPX90 signal will be fed.

PRESET PROGRAM SELECTION

Your SPX90 is equipped with a selection of 30 outstan-
ding preset effect programs which are listed in the ROM
CONTENTS AND CONTROLABLE PARAMETERS on
page 24. The preset (and user) programs are selected
as follows:
1. Use MEMORY INCREMENT/DECREMENT keys to
select desired memory number (remember, 1
through 30 are the presets).
2. Press RECALL key to call program in selected
memory number.
NOTE: The same process is used to select user pro
grams (memory number 31 through 90) once
you have edited and stored your own programs
in user memory.

EDITING: CHANGING PARAMETERS
The SPX90 offers incredible sonic flexibility, as each
effect type comprises its own set of parameters (see
parameter chart on page 24). These parameters can be
adjusted to suit your tastes and the tonal characteristics
of your musical equipment. We therefore recommend
that you examine each preset effect program, and
observe how these parameters affect the sound. You
will soon discover many new and exciting applications
for the SPX90's preset effect programs.
1. Select and recall desired program as described
above.
2. Press PARAMETER key to access the various
parameters available in the selected program. Each
time the PARAMETER key is pressed, the next
parameter in the list is called.
