Spillover

About spillover

Spillover refers to the functionality to keeping the trails of the delay or reverb audible after switching the effect off or switching presets, scenes and channels.

All FAS processors support spillover under certain conditions as explained in the Owners Manuals.

Spillover between presets

Spillover between presets is enabled or disabled in the Global Settings menu. It requires additional steps to make it work, as explained in the manuals. The setting in the menu applies to switching between presets only, not to scenes or channels, and neither to bypassing blocks.

"Global spillover settings only apply to preset changes. Spillover between scenes is, in general, desirable and controlled by the bypass mode and state of the various blocks." [1]

Turn off Spillover in the Global Settings menu if you prefer “silent” switching between 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.

In older firmware, the Multi Delay block, Ten-Tap Delay block, Plex Delay block and Megatap block did not support spillover between presets, but they now do in current firmware for the III, FM3 and FM9.

True independent spillover is not supported because it would require twice the processing power.

Spillover between scenes, channels

The Spillover setting in the Global Settings menu doesn't apply to spillover when turning off effects or switching scenes or channels. Delay and Reverb trails always ring out when switching scenes, depending on the effect block's Bypass Mode setting, see below. This is inherent to the way scenes work. When it comes to spillover, scenes work better than presets and are easier to set up.

"Spillover is in there but the "right" way to do it is to use scenes. If you stay within a preset and use channels and scenes the spillover is perfect." [2]

Spillover can be affected when switching between the channels 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.

Scene controllers allow more control over what happens with the sound when changing scenes.

Spillover when bypassing effects

The Bypass Mode of an effect block determines if the reverb or delay trails ring out after turning off the effect, or are muted.

Looper

The Spillover parameter also determines if a running Looper survives preset switching. To survive preset switching, both presets must contain the Looper, set to the same mode.
