OK, to program 1 of the 12 stomp switches:
1) Turn on small "Program" switch, with it's own LED.
2) Stomp on switch you want to program. The LED/Relay flickers briefly in confirmation. The switcher then selects the current LED/Relay setting for that switch.
3) Stomp on switches to your heart's content. The LED/Relays get toggled as you stomp, so you can hear what's happening.
4) Turn off small "Program" switch, it's LED goes off.

You have to repeat the procedure for each stomp switch.
