I downloaded an app called "Control (OSC+MIDI)" for my iPhone 4 to be able to use it with Ableton Live. I also downloaded and installed rtpMIDI for windows 7 which just makes windows do the same thing that's already built into Mac. I got it working once, then I turned it off, only to come back to try it again and find out it's not working.

I don't know what got changed or what could be keeping it from working now as apposed to a few hours ago. In the app, it allows you to select the destination to send the signal to but the computer no longer shows up in the destination list when a session is running. Anyone know the problem and how to fix it?
i don't like macs. nothing personal, just preference and experience
