midi fighter mod

[smallhouse]

I'm new to controllerism and soon to buy a midi fighter classic. on the circuit board it has (my vocabulary is awful btw) an analogue expansion kit. i want to know if i can just solder on (for example) a rotary potentiometer straight to the board or if i need to put anything else on?
any reply is greatly appreciated thanks

would be better posting this in the midi fighter sub forum i guess... there's plenty of info on this exact question there
