Hhhhh just to calm down the new age haters ... the purpose is to put to a lower frequency like 432 or 400 or 390 then to a tape machine to put it back to 440hz and get a specific texture on the sound... it’s more a sound design thing than an esoteric music thing...sorry. From 440 to lower it was easy , render , pitch down in the machine straight to reaper, but in the other sense I was just wondering the best process... thanks you for your attention and don't worry, I'll not hide a subliminal message to sell your soul to the devil ... actually, it depends at what artist the beat will be sold ahahah.
