Hi All, assume that for some reason you want to isolate certain partials of a acoustical sound and want to use them as a starting point/fundament (maybe literally as a fundamental) for a new sound. What would be then an appropriate technique to add harmonics or disharmonics to this heavily filtered basic sound? Some time ago I tried to realize this with wave-shaping (with other soft- and hard- ware, not kyma), because lots of people told me that this might be the appropriate technique for my goal. But the results rather dissapointed me (still I'm not sure whether the technique itself caused these dissapointing results or whether a possible poor implementation of the technique at that time with that special soft- and hardware was the cause). Are there other techniques, maybe also techniques unique to kyma, with which you can achieve better results than with wave-shaping? I heard about convolution in spectral domain, but don't know at this time how this can be implemented in kyma. Does anybody here have experience in applying this kind of techniques the way I would like to apply them? Can you recommend me some sounds/patches which could be an inspiration for me (in the context of what I want to realize)? Many thanks in advance. Best wishes, Florian IP: Logged |

I would suggest experimenting with the new InputOutputCharacteristic module as your waveshaper and follow the waveshaper with (optionally) a LowPassFilter so you can control the distortion harmonics. The InputOutputCharacteristic has the advantage that you can adjust it live to create any shaping function, so you can more quickly arrive at interesting results. Another approach would be to do a live spectral analysis of your original base sound and resynthesize it using a SumOfSines but NOT with a sine wave as the wavetable--instead choose something like the Saw0002 to add extra octave harmonics to the resynthesis.
