I can't currently afford a Diamond. But, if I'm understanding, it's a preprogrammed set of motions. Like, you could program a number of spins and stabs as a sequence to activate a set sound font to play only after that sequence. You choose the sequence and sound. Perform an accurate Obi/Ani spin to get Obi Wan's voice to play, etc.
Sorry, if I'm wrong. It's been a day, so I'm chiming in.
Not exactly, what you are talking about are the programmable gestures. The force sounds are activated by twisting the hilt clockwise twice (like accessing the diamond menu but without holding down the button).
Hope this helps.
