i was just thumbing thru the new issue of electronic musician and in a brief overview of roland's new V-synth they said it contained a "side band filter" that can "create harmonic sounds from inharmonic content and vice versa"...

sounds interesting... what exactly is a side band filter.. and can kyma do this?

Sounds like it might be another interesting application for the FilterBank with SyntheticSpectrumFromArray? I'm not familiar with the term "side band filter" but it seems to imply either that you would filter out the nonharmonic sidebands leaving only the harmonic components OR that the filter is created by ring modulating a LowPass filter?

sounds like a challenge! (for someone a bit more experienced with kyma than i am..)... who's up to it?

i've seen sideband filters or synthesis used in discribing modulation of the lowpass filter by oscillators within the audio-range or as way to claim something unique while doing FM (as a way around yamaha?.)

i've not played with the roland or creamware stuff which tout sideband filters. i gander an interesting approach, which they very well may do, would be to deal with this in the spectral domain. modulating the analysis freqs (carrier) by freq modulation could easily create highpass like sounds or sounds with 'missing' harmonics.
