I did something like this:

[phasor~]  [r~ pmfb]
|                |
|                |    [0\
|                |    |
|                [*~]
|              /
|            /
|          /
|        /
[+~]
|\
| \
|  [s~ pmfb]
|
[cos~]
|\
[dac~]

It sounds nice. just be a bit careful with the number box.

Hi list,  i was wondering if somebody have implemented phase modulation
feedback synthesis in pd?

The idea is that the phase can self modulate using the output of the same
signal.

I did some stuff with mutually modulating FM oscillators, using s~/r~ for one-block delay (64 samples).  Phase modulation is slightly different though...

Do anybody have implemented an example of this in pd?  any idea?

one simple patch attached showing the general idea

I'm actually planning to revisit this project soon, combining with the machine listening/learning/sequencing ideas of NoIn EP:

Making a parameter map of oscillator parameters for different tones and degrees of chaos:

Should have time to work on this project next in November, busy times ahead...
