Best way to connect a sustain pedal (digital vs analog input) and which type to choose (normally closed vs normally open)

[tago]

Hi,

i want to add a sustain panel to my NG based keyboard controller.

Which switch type is the best? Normally closed or normally open? (i somehow think normally open would be better, because the circuit is only closed on press = less energy consumption)

What would be the best way to connect them? Via analog or digital input?

Thank you

Ok, i found an answer here

If this is the best way, i'd like to know what kind of pedal is the best.

Normally closed or normally open?

Here is some talk about open vs closed:

In the second post someone says: "One disadvantage of a N/C is that with a pullup, as most switches spend the majority of their time in the un-pressed state, you will have increase current consumption."

If this is correct i'd get a normally open pedal.
