I leave this topic resolved in case someone is interested. It has to do with MIDI routing and LUA tools:
[Solved] Help: Code for MIDI routing of a single button of a tool
Basically it allows to use a simple button of the MIDI keyboard, to control any specific function that occurs to you.The potential of this is incredible!Yes, you can handle any command on the alphanumeric keyboard with the MIDI keyboard (CTRL+T (create Track), CTRL+K (collapse Track) etc, etc, etc, etc, etc, etc, etc, etc, etc…).
Basically you can control with your MIDI keyboard whatever you want.The only requirement is to create the specific functions with the LUA code.
Thanks to Danoise for the help!You should be a millionaire with everything you bring to Renoise.I hope that Taktik knows how to value you!You are saving the forums!
