Gen~ export to respond to MIDI Notes & on/off?

    Feb 10 2014 | 7:45 pm
    Ive successfully exported a Synthesizer made in Gen~ to AU that doesn't open in Logic X but works in Ableton Live 9. How do I set up the synth to be able to respond to MIDI Note messages as well as on/off messages to trigger the envelope?
    Thank you.
