I took a keyboard apart just to take a look inside. I realise you can use
the encoding piece to make you own pendant like you say but how do you get
the computer to realise that the input coming in is the signal for an
action? Like if I press 'A' it send a pulse that tells the program which key
I've pressed. But if I add another keyboard are not some of the keys, the
ones I use on my own pendant, then taken off the other board? Or does the
adapter for the two give the new pendant a totally different set of outputs
so the normal board stay fully working?

I'm just curious as to how this works,
