7 EDITING: CHANGING PARAMETERS
The SPX90II 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 charac­
teristics of your musical equipment. We therfore re­
commend that you examine each preset effect program,
and observe how these parameters affect the sound.
You will soon discover many new and exciting ap­
plications for the SPX90H's preset effect programs.
1. Select and recall desired program as described
above.
2. Press PARAMETER key to access the various pa­
rameters available in the selected program. Each
time the PARAMETER key is pressed, the next
parameter in the list is called.
