btw i wanted to ask about 3 really interesting sounds that i heard 1: 0:29 this whistle fartbass humming sound, is it like osis sound? but just with a bird whistle? thats my guess 2: 1:07 click roll + inward humming + air filter??? is so than its so clean wow, that sounds sick 3: 1:11 i feel like I've seen osis doing this sound, I'm pretty sure its just throat bass with like an open mouth filter i guess but my question is, what do i have to do to get it this clean (other than practice it) is there a specific tongue position or something
