As for the problem with the different pedal-possibilities:
After my research today I got the info that an analoge pedal could also used as digital pedal...but it would not solve the problem that - while one game needs a switch on for operation - another needs an interupted circuit to operate.
That for I have the idea to add a microswitch to the analoge pedal.
The idea is that the oridnary microswitch got both status at every position, one pin got a closed circuit when the other got it interupted.
