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
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.
