Hello.
I'm building a patch to integrate the launchpad in usine.
I try to change the channel of midi message when i switch the top buttons.
I'd like to send this mapped values for the midi learn function.
The problem is i can't prevent the original message (directly come from the launchpad) to be learned .

I'll try to explain.
I have a rack with launchpad midi input and output on.
i map messages to a midi bus ( the old version of usine had a "send midi to usine" very usefull.) .
I'd like that the new midi message created will be sent for the midi learn function but not the message from the launchpad.
I hope you'll can understant.

It's not so easy with the actual structure of Usine.
I'll take a look.
