Can I use Input Transformer to reverse polarity of sustain?

Greetings to all!

I am not necessarily a newbie, but when it comes to Input Transformer I am stumped. :frowning: Can someone guide me through using I.T. to reverse the polarity of the sustain pedal on my midi controller?

Many thanks!

Wow. Thatโ€™s perfect.

Thanks so much, Steve!
