midi out is for sending a signal from the software to external gear, that is absolutely correct, also if you use it you need make sure that your audio inputs are visible in fruity loops and you have your output from your gear plugged in so you can hear it in Fruity loops and record.......also sometimes the port needs to be set to 0 instead of -- try that...hopefull the midi out channel corresponds to the active one on the gear you should be able to hear your sound if thats set up.
