there's a sound you use a lot, like an organ that wants to be a siren, what exactly is it? i've tried organ sounds (messing with drawbars/ leslie/ overdrive etc.) and synths but can't quite seem to nail it  a couple examples: intro of you're free to do whatever you want to; history of the entire world (severe flooding alert, 2:09; microscopic speck (more staccato), 2:23); outside (the wind blows, 0:16)
it's a very commonly available sound but you have to play it in a certain way, and it's not an organ
