Just wondering if the masters of the Reaktor modules have used or created these..

...sound illusions?

i dont know how much practicality of having such a looping sound with what is continually heard in this clip... but i suspect some of the masterful reaktor creators and sound designers might have a possible method of utilising such a sound...

this particular sound is a continual pitch bend, which remains audible despite its continued perceived ascending tone...

have a listen for yourself... can this be reproduced with the ability to pitch shift in realtime and change the octaves or harmonics?? *shrugs

have a listen
