I can't seem to figure out how to send the midi signal from FL Studio to my keyboard. Midi from keyboard to FL works fine though. The reference manual just gave me more questions. "Enable Midi Output" and "Enable Midi master sync" are both checked and in the settings I have "Send master sync" checked. How am I supposed to know what port number to use? This just confuses me. My interface is an Mbox and I'm using FL Studio 8. Thanks for any help.
