I have made available Midi Channel aware MidiCodecs, how to install and use them.
How to workaround dirty pots\faders that cause issues inside of Reason.
Making mappings, include an interesting video on the "Reason Document" section that allows you control many functions (loop markers, transport controls, changing patches) from your controller.
This is a playlist to them all.
