I hope it's not too much info for you, RapidComposer is a bit frustrating at first but the end result is worth it. Don't worry if you can't work out all of this, someone else viewing or searching the forum might find it helpful.

The RC keyswitch control .rcCTRL only works in the full version, in the LE you need to make the keyswitch notes and set them to Absolute so they don't transpose.
C:\Users\User\Documents\RapidComposerV3\DB\Archtops Kontakt.rcCTRL
So you just need to copy the keyswitch notes to the rcCTRL like the one I posted above, * just change the octave up 1, so if the KS is C0 change to C1 in the Archtops Kontakt.rcCTRL for RapidComposer.

Here's Archtops Kontakt.rcCTRL with just a couple of keyswitches added fr the two Archtops, you can add the rest:
Code:

group="Impact Archtop"; articulation="Harmonic"; keyswitch="F1";
