Effects which don't support spillover
- Multi Delay and Megatap Delay don’t support spillover.
- User: "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." Cliff: "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
Keeping level changes when switching presets
If you use Mix and Level to dial in the 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
