Ableton Push 2

[theTwiddler]

I dont use push i got a lpd8. But i got a ableton or midi relatet question.
Is there a way to send a note on and off signal by pressing a midipad and when releasing the pad sending a on and a off signal in the same time again?

I want to play with some fx racks that should just be activewhen i press a button. When i release the pad i want the fx to be off again. Right now i gotto press a pad twice for that. First press activate 2. Press deactivate.
