FL STUDIO rewire : can't play on my synthesizer

[Meathook]

Hi,

If I use FL STUDIO as a rewire in ABLETON,
I can only play the FL instruments with my computer keyboard.

What should I do to make the FL instruments available on my synthesizer??
(if FL is not rewired, the FL instruments works on my synthesizer)

Thanks,
Patrick

Problem fix. Just had to disable my midi port in live.
