Ableton Forum

I am sending midi to ableton trough IAC mac Driver from a patch in pure data. Everything appear to be fine, the light on the right-up side of the screen of Live is flashing, but i can't get midi on the channel.
In the Midi input setting of the channel i have selected the my "fake" midi device and i have all channel in.
I am sending to ableton a msg: 45 note number, 100 velocity on channel 1 and after 100ms a note off msg.
thanks
