What is spillover?
Spillover is a feature where the trails of a delay or reverb can still be heard after switching to another preset or scene.
The Axe-Fx II, AX8 and FX8 support spillover, under certain conditions which are explained in the manual.
Spillover is enabled or disabled across all presets in the Global menu. Note that enabling it still requires additional steps per preset to make it work, as explained in the manual.
The Multi Delay and Megatap Delay effects don’t support spillover between preset switching.
Spillover may be affected when switching between the X/Y states of an effect, if drastically different algorithms exist between the two states. For example, if one scene has a Digital Delay and the next scene uses a Tape Delay, spillover will probably not function correctly as these modes use different algorithms.
Forum member "I have two patches that both has delay blocks disabled and when I switch between these patches via MFC the delay spillover sometimes kicks in really loud." Fractal Audio: "This can happen if you rapidly switch between presets many times. The unit requires a small amount of time between preset changes to clear unused buffer space. This is done as a background task." source
Preventing spillover-caused volume bursts when switching presets
If you use the Mix and Level parameters to dial in the desired effects level, the volume level of the reverb and/or delay trails may change when switching presets. This can be prevented by keeping Mix and Level at fixed values, and using Input Gain to set the desired effects level. source
