1. Create a single patch containing stomps for two sequential patches from which you'd like to transistion with spillover.
2. Enable all the stomps in the patch for "sound one" and disable all the stomps for "sound two".
2. Turn "Trails" on in the System Menu for the patch.
3. Assign all of the stomps to the same Footswitch.
- Highlight the first stomp and hold ENTER for two seconds
- Press the desired footswitch (say, FS1)
- Highlight the next stomp and press FS1. Repeat for all stomps
5. Step on FS1.
The two sets of stomps toggle back and forth from within the same patch, with trails intact. Note that you can also toggle between two amps this way
