Enable- Enables or disables all effects for both the Upper and Lower layers.
Mode- Allows selection of either a common or individual set of Distortion, Phaser, Chorus/Flanger, Delay, and Reverb effects for P-10's Upper and Lower layers.
Global- Both the Upper and Lower layer are run through a common set of effects. This is useful when you'd like the same effects settings for both layers when creating stacked Double or Split patches.
Dual- Upper and Lower layers are each run through independent effects sections. If you're using an older computer, be aware that this is more CPU intensive.
The Limiter effect is always global for the both Upper and Lower layers.
