Yamaha S-03SL Owner's Manual page 54

You can set the desired Effect type for each Effect
section as well as its parameter values for each Multi in
the Multi mode. By using Variation as an Insertion
effect, you can apply the effect to only one of the Parts
(see illustration below).
As shown in the illustration below, the Reverb section
and Chorus section function as System effects, which
process all of the Parts, according to each Part's effect
send setting and the global effect return setting — just
like on an actual mixer. When using Variation as an
Insertion effect, the signal connection is serial, and the
effect is applied only to the selected Part — just like
patching in an outboard effect on a single instrument
channel.
