Thanks to you both, I have had to read through all the options a fair few times to get my head around what I am trying to achieve. I did not realize that you could do both blade detect and blade ID at the same time, I thought it was a one or the other situation from reading the latest ProffieBoard manual (which is what the reference was in regard to saying page 21 - apologies for the confusion).
My main goal is the following:
When the chassis is removed and switched on it plays a preset of sound fonts and blade styles that are separate to when it is inserted to the hilt; lets call this the Chassis Array. I don’t want to have to turn it off and on again for it to automatically switch preset arrays when inserted into the hilt.
When inserted into the hilt I want it to play a sound and switch to the different preset array (bladein.wav and bladeout.wav) which includes all my other blade styles and referenced sound font folders. Let’s call this the Hilt Array.
When I insert the main blade I don’t mind if I have to turn the saber on and off again, what I am after is switching to a ‘copy’ of the hilt array except that I am able to have the sub blades of the NPXL connectors off (black). So I assumed I would need to switch to a third array in order to have a corresponding blade style(s).
From what I have read so far, Fredrik’s option suggestion (2) of using both the blade detect and blade ID would be the best.
I am a little confused as to the con of no effect when blade is inserted/removed; does this mean no effect as in inserting the chassis into the hilt, or does this mean no effect as in only being able to define the number of LED’s for that blade resistance?
My confusion comes from those manual pages whereby I am just looking at the config files examples. The blade ID resistor function example on page 22 shows almost exactly the same thing as the blade detection example on page 24 for being able to switch preset ‘arrays’/configs. Hence why I didn’t think it was possible to do both, and have no idea how that would look together nested into the config file.
To do the blade detect option easily, from what I understand, is to have Aux2 Button 3 go to the blade present pin on the 10-pole connector. On the hilt side of the connector I would have this short to LED Powerpins2+3.
Then to utilize the blade ID function simply have the resistor in the blade bridge data 1 and LED -ve (Powerpins2+3 again) with the appropriate resistor.
Did I get that right? 
Also would be super grateful for the little questions:
Can the Feasycom be wired without issue using the SD power (Fredrik’s configurator) vs. the proffieboard manual diagram? I didn’t know if there was a difference due to manufacturer. I couldn’t care less about idle off as I always turn the power off when done.
Will negating the circuit being broken on the negative line from the battery at the recharge port be a problem? I don’t see how, as there does not appear to be a complete circuit with the board.
Thanks again for your help.
P.S. - Sloppy, all my surfaces in my place are black except my brown wood floor. But, yes, I realize now I could have put down some sheets of paper for better contrast. Point taken.
