EXPERT: Toe Switch

The ultimate is an Expression Pedal with a Toe Switch.
If you have a Boss FV-500, look here how you can modify it with a Toe Switch.

PART 2: Now we set S30 to switch the CC of Expr1 between CC41 and CC33.

Because the toe-switch is momentary we can't use stomp, but have to use step-thru.
