Using plugins like Bufferoverride from DestroyFX

Hi everyone, I’ve owned my organelle a while now but never really dived into making use of it due to being distracted with other gear.

From what I’ve gathered through reading through various posts online, it seems that using a plugin like Buffer Override by DestroyFX on the organelle is possible?

Can someone explain to me why / how this is possible and point me in the direction to some more info I could read to understand this process better? I’ve struggled to get a proper understanding of all this via the information I’ve found so far.
