The confusion arises from the fact that there's two layers of stuff going on here.Control Switches allow for 'Momentary' switching. The definitions of 'Momentary' and 'Latching' should be consistent.
So with 'Stand-In' switches, a 'Momentary' switch can not act as a 'Momentary' switch. It can only act as a 'Latching' switch when set to 'Follow Hardware'???
I thought that the 'Virtual Toggle' option was added for just this reason. To turn a 'Momentary' switch into a (Latching) 'Virtual Toggle' switch that stays in sync, as it switches at every change (open or closed).
What possible use case would the 'Virtual Toggle' setting be used for, when using a 'Stand-In' switch?
I'm confused....
The first layer is how the switch will behave. The FM3 generates an internal control signal based on what the pedal does. "Follow Hardware" means that the internal signal follows the hardware. When the footswitch turns on, so does the internal control signal. When the footswitch turns off, the internal control signal turns off. "Virtual Toggle" turns a momentary switch into a toggle switch. When the footswitch turns on, so does the internal control signal. When the footswitch turns off, the internal control signal doesn't change. But when the footswitch turns on again, the internal signal turns off. See the pattern? Two stomps of the footswitch causes one on/off toggle of the internal control signal.
The second layer is all about what the box does with that internal control signal. Think about bypassing a Delay block with just the FM3's built-in footswitch. That built-in switch is momentary, but when bypassing an effect block, it behaves as if it were latching. One stomp engages the effect, and the next stomp turns it off. Even though the actual footswitch is momentary.
In that second layer, only Control Switches allow that behavior to be momentary. It makes sense in its own way, but it's not completely intuitive.
