Hi, I'm the main programmer for Audio Zone Trigger.
I'd like you to send me an email with all the details of this project. There is a good chance that I can put a new "cancel feedback" feature directly in Audio Zone Trigger, this would be way cooler and faster than using many software hacked to work togheter.
Please send me the info via email, I'm not sure if I'll be back on this forum.
Have a nice day!
