Hello,
Sorry to hear you are having issues. The only setting that will determine how spillover works is the spillover time in the system settings. Have you confirmed the spillover time is higher than 0? Something like 10-15 seconds is a reasonable time to use.
How are you using the pedal when you say that spillover is not working? An easy way to confirm that it is working is to create a long reverb or delay tail, play a chord or note, and then switch programs. The tails should keep going after the new program has loaded.
