I recently had an idea about phase shifting: A phase shift of a given degree only makes sense for a single frequency (e.g. a simple sine wave). When working with more complex material you can actually do no phase shift, all you can do is a fixed delay where all frequencies are shiftet by the same time amount.
But if you did a FFT first you could apply the phase shift to every single sine wave, depending on it's wavelength, right? I have no idea where this might lead, but I'd love to hear what it sounds and if there could be any use of it.
However I have no idea for a starting point - is there any way to split up the individual sine waves so I can individually adjust them?
Cheers,

Is there a way to achieve this with MXXX?

it shouldn't make a big difference in sound.-

Have a look at allpass filters.

@frizzbee:
But the phase shift would need to be different for every harmonic - is thta possible in MPowerSynth (which I dont own unfortunately).
@nusucherror:
Ok I will. :-3

yes it basically is a fft display with magnitude and phase display which you can alter as you want. doesn't have to be mpowersynth, you can try that with so many other plugins too which have a osc module like that. but like with an allpass filter the changes are just visually and not audible. that's the point.

Ok... In my fantasy it would change the sound in a weird way, but it seems the idea - while technically interesting - may be quite boring sound-wise

Well, from my experience it doesn't really do too much good really 
. You can test on the oscillators as frizbee suggested indeed, that should give you the idea, but from my experience it is mostly audible on percussive stuff where it sort of messes up the initial transient. To get you some idea, try MStereoSpread and use a high number of Bands and process a drum loop for instance. It will sort of mess up the phase in a similar way, if you mind that the effect is stereo, just put say MStereoScope after it and let it audition Side signal.
Another effect you can try is MFreqShifter. Set depth to 0%, so that it doesn't shift anything, and it will basically shift all frequencies by approximately by 90 degrees if I remember correctly, but I may be wrong in this.
Finally you can use MMultiBandConvolution and use a Filter (instead of File or Reverb tabs) and set it to Hilbert, then you can have a top quality 90 degree shifting. It's quite an important feature for some more complex algorithms like the frequency shifting, but alone I don't think it is very useful.

Oh cool, thank you all for the responses, I will test it, although after reading all the postings my expectations to get something interesting are rather small now
