[PD] FM matrix with feedback

[William Huston]

You may want to look at Martin Brinkmann's patch Chaosmonster1.

http://www.martin-brinkmann.de/pd-patches.html

I studied it about a year ago, and gave up trying to understand how it
works. But it makes fantastic noises.

Martin says it "generates noise- and 'chaos'-sounds with six oscillators
with mutual frequency, filter and ringmodulation. Some similarities
to the famous 'heishere' reaktor ensemble by lazyfish."

my friend made in reaktor using a block size of 1 (sorry, don't know the
full details of that, but he says he can get 1 sample delay for the
feedback)

the order forcing using subpatches like in G.05.execution.order help patch,
but that doesn't seem like it will work here, as we still get DSP loop
errors when trying to connect the output of one osc~ back into the
frequency input of the others.

without getting DSP loop errors is with s~ / r~ pairs, which seem to only
work at blocksize of 64 anyway?
