Starting program when plugging in 3.5 jack

[gambit07]

Hey guys, I used S2P for a little bit and unfortunately was disappointed with the performance, however I really liked the ability to open the program automatically when the headphone jack was plugged in. I'm wondering if there's a way to program that to open up a different program. I'm using Conduits Pocket Player so ideally I'd like to have that start. Any help is greatly appreciated! Thanks
