External Instrument, allowing you to control rewired instruments with Live's rack
knobs. I think the image is self-explanatory, but the gist of it is: you select a
Reason parameter from the drop-down on the new version of the External
Instrument, and map that parameter to a macro by using the dummy
"parameter" button. What this effectively would do, is telling the macro knob
what CC to pass on to the Reason device.
