Effect Types and Parameters
In this section, all effect types and parameters of the modules in the PFX-9003
are explained. The effect types and parameters that can be used in each
module are listed below.
The [A] symbol indicates that this parameter can be assigned to the ARRM
function. The parameters shown in black reverse are assigned to sliders in
play mode.
