Ok, got the latched pedal through and am a happy camper.
Difference between the latched and non latched version is that with the non latched version, you can jump straight back to the hi-hat and it works as normal.
With the latched version the hi-hat pedal is redundant until you unlatch the switch.
Now......if I add a potentiometer to the latch switch, can I choose between closed or semi closed as. Mentioned in an earlier reply?
