I came across with this video that shows a way (starting on 1:07 in the video) of creating the Shepard Tone illusion, by basically using any sound effect in Pro Tools. In my search of finding a way of achieving the same effect in Kyma, I found Cross input w/Endlessly rising Shepard tone thru Vocoder and also SheppardGlissando and ShepardContinuousSpectrum prototypes. But, I can't seem to achieve the same results as the ones shown in the video.
1.- I used Cross input w/Endlessly rising Shepard tone thru Vocoder for this sound (sfx used in Sample Up/Down Prototypes).
a) Why is there only a frequency tone generated, that goes up in pitch (that's actually the Shepard Tone effect), instead of just geting only the SFX (used in the SampleDown and SampleUp Prototypes), going up in pitch?
b) What am I doing wrong here?
c) Is there a way to just lose the frequency tone?
2.- It seems that the SFX in the Sample Up/Down is used only as a "modulator", or "trigger", for the upper part of the Sound. ( Starting from the Resynth w /saturation Protype all the way back to the Ramp Sample Prototype).
Am i wrong in this assessment?
3.- In the SampleUp/Down Prototypes, the 1 repeatingRamp: !Dur s and 1 - (1 repeatingRamp: !Dur s) expressions were used in the Scale parameter, in order to simulate the fades in and out, demonstrated in the video.
Was that a correct decision to control the Scale parameter, or would you recomend something else, in order to achieve the fade in/out process, explained in the video?
4.- In the SimplePitchShifterUpwards/Downwards the following expressions were used in the Interval parameter, in order to simulate the pitch up and down, demonstrated in the video:
(1 repeatingRamp: !Dur s) * !IntervalUpwards and (1 - (1 repeatingRamp: !Dur s)) * !IntervalDownwards respectively.
Was that a correct approach to control the Interval parameter or would you recomend something else, in order to achieve the pitch up/down process, explained in the video?
5.- Is there any other way/technique or Sound that you would recomend me to look into it?
Thank you very much for your help and time!
