Re: [music-dsp] (Novel?) "Modal Phase Rotation Synthesis"

After looking at it I think probably you can but you need trig calculations every sample when you change the frequency and quite some additional calculations for the WGR every sample in this case. So its cheaper to use a standard oscillator with a sine aproximation for phase mod.  in both

Re: [music-dsp] (Novel?) "Modal Phase Rotation Synthesis"

Yes, I think you can do phase modulation with those filters. They are referred to colloquially as "phasor filters", because their phase is manipulated in order to rotate a vector around the complex plane... On Tue, Apr 3, 2018 at 8:16 AM, gm wrote: > > Yes it's related, I

Re: [music-dsp] (Novel?) "Modal Phase Rotation Synthesis"

Yes it's related, I dont recall if I used one of these filters in my first implementation which was several years ago. I used a complex filter before I used the SVF and AP. But I think you can't do full phase modulation with such filters? I think that was my motivation to apply the rotation

Your idea seems to bear a few similarities to this (just in case you haven't seen it already): https://ccrma.stanford.edu/~jos/smac03maxjos/ On Mon, Apr 2, 2018 at 2:46 PM, gm wrote: > > I don't know if this idea is new, I had it for some time but have never > seen it

[music-dsp] (Novel?) "Modal Phase Rotation Synthesis"

I don't know if this idea is new, I had it for some time but have never seen it mentioned anywhere: Use a filter with high q and rotate it's (complex) output by the (real) output of another filter to obtain a phase modulated sine wave. Excite with an impulse or impact signal. It's
