Digital Effects

System Effects and Insertion Effects

The reverb, chorus and DSP effects are divided into two different types or methods or
operation.
There are two types of digital effects: system effects and insertion effects.
System Effects
Applies the effect to all of the parts input to the mixer. You can set the amount of effect
applied with the depth and return level parameters. Reverb and chorus are both system
effects.
Insertion Effects
Applies the effect to only one designated part before inputting the signal to the mixer. You
can effectively use the digital effects by applying the desired effect to the specific part.
With the insertion effects, only the DSP depth can be set.
The illustration below with the various audio components (instruments, effect devices,
and a mixer) represents the inner workings of the DSP effects of the PSR-740/640.

Multi Effects (DSP1-3)

the sound of the voices.
