Simple Feedback FM

November 2, 2008 | 5:59 am

Does anyone have a really simple example of feedcack FM i could have a look at? Just a simple cycle feeding back onto itself should suffice, just not sure about exactly how to implement this myself. I’m guessing you could use tapin~ and tapout~, but i’m not sure how to scale the values from tapout~ and how to feed it backing into the signal chain.

regards,
matt

This isn’t as simple as it seems… You can feedback with
tapin~/tapout~, but this will create a signal vector of delay. Thus it
would still sort of work, but with different results than a DX synth for
example. It would be necessary to create an external, either in c or
maybe in Java with mxj~…

just multiply the signal with a float value less than 1. to scale it.
