Reply to Novation Launchpad Trick

This is a liitle trick that I found about the launchpad

You can Feedback Your Midi Msg that send to a launchpad Midi-In port
If you don't understand this I mean How can U Make Launchpad Push It self

Just send MIDI Controller Number 16 (CC16) out then the launcpad will send the same midi message back to it's input port it self.
I found only CC-16 Vel. 0-127 that mean You got 127 value to do map on traktor
Hope this help
